Purchased an EOS Carbon Fiber Diffuser for my 2026 Z06. Evan was a master at customer service. Appreciate all that FFPerformance and EOS did to ensure best quality and delivery. Highly recommend speaking with Evan for any requirements. read more

I bought a wicker bill gurney flap for my GT350 . Lead time says up to 2 weeks. It took 5 weeks. No updates, no communication. Just a smart ass reply to a negative review. Well I finally got the price of crap and all the rivenut tools and drill bits they say to buy are ALL WRONG!!! Wasted enough time on this junk. It sits in my trash can. read more

I wanted to write a review to help anyone buying their stuff out. I ordered a simagic wheel base from them. First and foremost, Evan was very cordial and friendly. I'd recommend working with him. I can confirm I received the full order and everything is in new and working condition. One thing to note, is they have a very strict return and cancellation policy with a high restocking fee (35%). I understand a small business needs to protect itself, but given the many negative reviews, I think they should re-evaluate this. My experience was I ordered my wheel base. it didn't ship out within the 5 business days they stated, but I ended up reaching out to Evan to switch for a different product anyway so it worked out. Took another couple of days to get the order out and I shared my concerns with them based on these reviews and BBB complaints. In the end, they followed through with the order and delivered in 2 days once it shipped. Free shipping too. My reason for deducting 1 star is I think the return and cancellation policy is strict and more bottom dollar protection than client protection. I also think 5 business days to ship something out is a bit much considering other small outfits can ship out much quicker. That said, I caused a ruckus with them because of these negative reviews and informed them of my concerns of getting scammed. They followed through and delivered on their end, so no complaints from me on that as I'm the one who caused the situation to arise. Because of that, I promised to leave a review to help build them up. They've got some stuff to work on, but if you're willing to wait a few more days than your Amazons, they'll follow through. read more

Ordered a $5k brake kit which they promised to send straight away. Three days later they alleged to have dispatched the item but after a thorough review, both the tracking link and logistics number were found to be fake. Going by most other reviews I think it's fair to say this company is dodgy and would recommend you avoid. read more

Placed an order for. Cube Controles F-Pro sim racing wheel that was on sale for $699.00, regularly $899.00. After 2 weeks, I was informed by the owner Charles that they had made a mistake on the pricing. He then said he would not honor the sale price saying, "I am the owner of a small business." I talked to him on two occasions before this to inquire as to why the item had not shipped. He told there was a ten day lead time on shipments without ever trying to tell me there was a price discrepancy. Function Factory Performance should have honored the sale price. The owner, Charles, was willing to take a hit to his, and his company's reputation over the lost revenue rather than doing the right thing. I would not recommend doing business with Function Factory Performance or the owner. I would give them a ZERO star rating if at all possible. read more

I order an Alpine TRX sim racer on 15 August. After the order was in processing status after 10 days I gave them a call. They were responsive, and told me that they would look into it. I called again at 21 days, Charles let me know that the orgin company was having issues. This was confirmed by Trak racer us on reddit. We spoke continuously after this conversation. Things were resolved on 17 September, I received my order status update and confirmation codes. I also had an issue with FEDEX, they delivered to the wrong state. I was able to keep track of everything using the tracking numbers provide by FFP customer service. Everyone that I interacted with treated me with kindness and respect. read more

BUYER BEWARE! Problem 1: Website lists items as in stock when in fact they are not. Owner claims his website does not offer "live stock" on items and to read the fine print on the bottom of website. This is simply just false advertising with a legal loophole. Scam artist behavior. Problem 2: You will not get your items if you buy from this website. The owner will continue to make excuses to justify the delay on shipping until you are out of your window to file a chargeback. Luckily, I noticed this trend and filed a chargeback. If you want to pay hundreds or even thousands of dollars for parts that you will never get then this is the website for you! Otherwise spend your hard earned money elsewhere! read more

Charles (Owner) and Lester (Highly Skilled Technician) over at Function Factory absolutely knocked it out of the park on my 2024 Corvette C8! I delivered my car to their shop in Thousand Oaks (very cool place by the way), to have a New Borla ATAK exhaust system purchased and Installed by this squad. I am also a business owner of 35 years, who has owned high end cars my entire life. My expectations are always high, and I take great care of my rides. These guys installed my exhaust with precision and the fittiment was flawless. It sounds demonic! Exactly what I wanted. They even completed the necessary "re-learn" process required by the manufacture. They set the bar for quality and service in my book. read more

I'm going to go against the grain on this one. I ordered a $650.00 Carbon Fiber hood scoop for my Ford Raptor. After two weeks, I hadn't heard anything and tried to call. I was placed on hold for 40 minutes and gave up. Later, I tried again and just left it on hold while I worked in the garage, waiting for someone to pick up. Eventually, the call was hung up at the other end. I went online and happened to see all these negative reviews and thought I would be in for a battle to get my part. I sent an email and requested that my order be cancelled. The email was answered saying they had been swamped by Black Friday orders and phone issues. This was Monday and they said my part would ship by Wednesday. When I read through the reviews, it seems others were getting the same story. I had purchased the part with my capitol One card and figured I would have to wait until Friday and give them a chance to ship before I tried to dispute the charge. Well.....on Tuesday evening, I got a notice they had created a label, which can be done without really shipping the part. However, the next day, the part was at FedEx and enroute. I know this is a small company and I'm guessing they got overwhelmed with orders. I know it's no excuse, but I eventually got the part. It was $200.00 less than any other offerings. read more

This company and the owner are a bunch of thieves. DONOT BUY ANYTHING FROM THEM! I ordered lowering springs from these jokers back in Dec 7, 2022 and they ghosted me for 5 months. I've made repeated attempts to contact them to cancel my order. April 18, 2023 I get a random email stating they are shipping my item. I immediately replied stating I don't want the item anymore and I don't even have the vehicle anymore. Their response was to sell it locally or on eBay.. what company tells you this? Complete trash. Against Don't buy from these thieves. I've reported them to the BBB and everywhere I can. read more

Refused to ship part, then refused to process refund and charged a restock fee. All while delivering terrible customer service, caught in multiple lies. Avoid this company read more

I recently shared that Charles sent me the wrong product then charged me a 15% restocking fee plus return shipping. He then proceeded to bill me for the correct part, after he told me could not ship until the other refund had been. Meanwhile, I had purchased the part elsewhere. He refuted my claim, saying I got to him. He is a liar. Here is a photo of the debit from my checking account Charles likes to mention that it states in all sales agreements that there is 15% restocking fee. There was no paperwork involved in my transaction with him. It was all handled verbally, over the phone. So many negative reviews about this place, notice I did not call it a business, they speak volumes about Charles. He paints himself as the victim. But he is anything but a victim. He is a victimizer. He likes to twist things around. He even accused me of harassing his employees when I did was suggest they check out the reviews. STAY AWAY FROM THIS GUY!!! read more

exhaust was ordered (5k) and shows up in in pieces from XPO. rather than call me, they decided to produce another one. I told them I wanted a refund but their "website policies" which you all should check before purchasing, said otherwise. I filed a claim with my credit card and was denied. So I ate 5k for an exhaust that cant be used. this was after they threatened to call Law Enforcement on me to make sure I didn't commit fraud lol. stay far far far far far far far far far far far far far far far far far far far far far far away from this company. read more

Charles and FFP are nothing but scam artists and no one should ever do business with him or any company he is associated with! Ordered a product 8 months ago and after many non returned emails, phone calls and lies he never produced the product! I along with many others were caught in the same scheme! Instead of saying hey I apologize here is a full refund he tells everyone to file a chargeback as he will not refund your money then claims he is a victim of chargebacks! This is continuing to happen over and over to others! Avoid at all costs! read more

I placed an order on Thursday 12/2/21 after chatting with Taylor in regards to some headlights. I was told that they'd get back to me and ensure they're in stock but said they should be. Because the lights were hard to find, I placed the order and never heard back if they were in stock. A few business days later, I chatted with Taylor again after sending an email and getting no reply. I was told that the headlights were in stock. After 5 business days and another email not responded to, I chatted with Taylor and was told that my headlights are still processing and tracking would be provided soon. The estimate was vague something like this week or next week. I emailed the company 3x and never got an email reply. Their website states that orders will be shipped next day. The order confirmation email says 3 business days to be shipped. After 6 business days (12/13), I called to cancel my order. I was told by customer service that there was confusion with the warehouse and they didn't know if the headlights were even in stock! I was told I would receive an email confirmation for the refund. I did not receive any email communication that day. I called the next day and was told same thing. And I called the next day and was finally given a refund and received a refund confirmation email. Of course the customer service rep did not mention the $64 that they shorted me. I filed a credit card dispute because this is terrible customer service. There's still no proof that they even had the headlights in stock especially since they never once emailed me or gave me an update. The owner replied to my Google review but never actually did anything. I've updated my review to reflect my entire experience and posted on various website to warn other buyers! 12/20: Donnie called me and apologized about the $64 that was shorted and said a refund was issued. This time it was done before he called me so I appreciate that he at least made effort and wanted to update my review. read more

Spent $450 on parts that needed to ship for a time sensitive project. They immediately charged my credit card. 1 week later I had not received any notice of them shipping. I tried calling to cancel my order but they never answered their phones and their voice mail was full. Sent several emails cancelling my order and requesting my money back but never got a response. Finally reached out to Charles Siritho on FB Messenger and told him about my troubles to which he replied "cool". Here we are over two months later and I have not received my refund yet. This business is a scam and Charles Siritho is a lying con artist who spends the money he scams on food he can't afford and bad hair dye jobs. When I told him about my experience and provided a negative review on FB, he threatened to find my social security number and post it on the internet. I've attached the screen shot for proof of that. Avoid this company at all cost. read more

Do not warranty products and bumper tab connection is very thin plastic .do not purchase from

Don't have items in stock , even when their website says item is in stock. took almost three weeks after I ordered wheels from them to find out they didn't have what I ordered from them and would be several more weeks before they might be able to get the wheels, Even though they were supposedly in stock when I made my order. takes several days of phone calls and emails to get any type of response from them. customer service is horrible. after 3 weeks of getting the run around. I gave up and ask for the money to be refunded. be careful when doing business with them, they might not have what they say they have in stock read more

DO NOT DO BUSINESS WITH THIS GUY! I was going to order online, but I had questions and wanted to make sure I was ordering the correct part, so I called him. He told me I was indeed ordering the incorrect part and told me what the correct part was. So, I ordered what he said I needed. He failed to mention there was choice of finishes on the carbon fiber splitter he was sending. when it arrived, it was not the same as the other carbon fiber parts I had on my car. He said I could return them, but there would be a 15% restocking fee plus the cost of the shipping label. I told him that was not ok, since he fail to properly represent the product. He never said another word regarding a restocking fee is shipping label. He did send an email telling what my refund would be with the difference in the cost of the correct part. It was around $112. However, he went ahead and deducted the 15% restocking fee plus the shipping label, leaving with about $12 for refund. He made unauthorized charges on my credit card after telling me differently. I wish I had read other reviews first. read more

I ordered a rear spoiler and skirt kit for my 08 C6 supposed to be in stock on Feb 26, I was told they should arrive by the weekend so about a week. When the weekend came and went with no shipping info I was concerned and called them. I did speak with them and was told they were having some shipping issues and it would go out that week, I then searched the company and saw all these bad reviews and thought oh S**t! Anyway a label was created the next day and to my surprise the shipment was picked up and actually headed my way. I received the shipment 3/10 which was 2 weeks from the date I made the order, it was packaged well and good quality. Things happen and I get that, 2 weeks isn't bad and they had the best price out there. All in all they were responsive and got my order to me in a reasonable time. They may have had some issues in the past but most companies have had a hard time recovering from supply issues since Covid, my situation went pretty well and as a small business owner myself I felt I needed to actually submit a review. Hope they keep it up and regain the trust of their customer base read more

I ordered a part online. It costed $324.99. I never got an email of the order conformation so they must not have a very up-to-date system. A few days later my son said it was the wrong part so I called to cancel. No one ever picked up after 30 minutes on hold so I emailed "support " to cancel. A week later no email back. Called and was told I would have to talk to the manager to cancel. Waited on hold for over an hour and got disconnected! Called right back and the guy said "oh yeah I talked to the manager, it's fine we will cancel and refund" I asked for a confirmation email and he sounded confused but then said yeah sure ill send a confirmation email.. that never happened. It's been a week and still no refund of my money! This place sucks! Take your business elsewhere!! read more

The most terrible experience I have ever had is dealing with function factory performance. I ordered an upper and lower grill insert for my car, then got a confirmation number sent to my email. I waited one week and didn't get another email with a tracking number so I called them. The guy that answered, told me to send him the tracking number via email which I did. The man told me that I had never ordered anything from them, but he would get back to me. A week has gone by and this gentleman never contacted me again and every time I called no one answered and you can't leave a voicemail because the mailbox is full. Still cannot get a hold of them on the phone or email. read more

Absolutely garbage scam artists - they take your money and do not deliver. Then, when you report them to your credit card agency, they lie and try to say they shipped out the items you ordered and you kept them. These people belong in jail. read more

Do not recommend this company under any circumstances. I placed an order for a backordered item - despite the backorder, the amount was immediately charged to my payment method (most reputable companies charge on ship date). I realized only a few days later that I did not want the item and requested a refund... FFP was nice enough to issue me a refund MINUS 25% of the cost of the item, because it must have been a very complicated process to cancel the order of an item that isn't in stock and probably not even in the process of being made. Given the circumstances I don't think it was justified to charge a 25% order cancelation fee which is my whole complaint with the company. They must be hurting financially and using that to take advantage of their customers. I hope FFP understands that the $100 they managed to get out of me canceling my order only caused them to lose many thousands of dollars in sales from expensive car parts that I would have purchased in the future. I am glad that it was only a $100 lesson learned for me to realize not to conduct business with this company any more. read more

I ordered a front splitter in November, 2022 and this "company" strung me along with excuse after excuse until they knew my 90 day period to challenge the charge had passed.

I canceled my order 2 months ago and still have not gotten my refund. This company is a SCAM do not buy from them

Seems like a scam website, avoid! Took my money and never received a product nor refund. Stay away!

BUYER BEWARE - Avoid this company at all costs. I ordered a part that said was 'in stock' on October 15, 2022. They charged my credit card the full purchase price plus shipping protection on October 16, 2022. I have not received any shipment and they will not provide a refund. I have sent many e-mails. Sometimes they respond but not if you are requesting to cancel your order or requesting a refund. I have tried to call but only receive a voice message stating that I am calling after hours (which I am not) and I can't leave a message because the voice mail is full. I have filed a complaint with the Arizona AG's Consumer Protection Office. I encourage anyone else who has been ripped off by this company to do the same. read more
