Awesome experience, they care about cars and it shows. Professional and timely, will go back for future needs.

Eric and the team at Supreme Power are beyond excellent. I always have 101 different questions and they are always answered promptly and directly. I've been shopping here for years for all my parts (have a porsche 991 gt3, 993 911 C2 and a bmw E46M3). They can source a lot of hard to get items and is reasonable in their pricing. I got all my Manthey Racing parts from Supreme Power. read more

Eric, did a great job with my 2014 911. He knew what I wanted before I did and made it happen. Pricing was good too.

Great team and great service! Gave me a much better deal than the other shops around. Parts came in on time which is always a plus when building a vehicle. Would highly recommend!! read more

I'm always taken care of at Supreme.! Kim and the boys know their stuff Good service and great parts. Really appreciate it. Thanks KG

Definitely surprised me how good their customer service is, no hassle at all and very trustworthy company. The wheels also shipped super fast! I will definitely be coming back! read more

When you want a specialty shop that goes above and beyond, this is the place. They are an excellent source of very difficult to get parts for Porsche. Also, they're not the kind of place to nickel and dime you for the small things. So far I've gotten some really rare and great service from them. read more

Supreme Power - Installation of my Manthey Roll Bar at Supreme - Auto Customization Near Me - Fullerton, California

Needed tires for the s2000 and a place that wouldn't scratch our newly refinished wheels. - Kim gave us a great deal on four Michelin Pilot Sport 4S tires (better than tire rack and America's tire). She made it very easy to pay online and set up an appointment. - Tires arrived on time. Shop was SUPER CLEAN. Waiting room was nice. The tech did a great job of installing the tires without scratching the wheels, and we were in and out of there pretty quickly. read more

I've been a customer with Eric since 2000, and I've watched him grow from a humble little operation to where he is today. He's always done me right and always fair with his pricing. Somehow Eric has this ability to get those hard to get parts, I was one of the first lucky recipients to score a set of BBS CH's when they first came out back in the day. Recently we lowered my wife's M3 and had spacers and other goodies installed on her car. Shop around but go to Eric last because he will hook it up and if you need an install he's the man. read more

I've taken my GT4 here twice. First to lower the vehicle and 2nd to install my race exhaust. Supreme Power has earned a loyal customer for life and I've already sent referrals. Kim and Will have been absolutely amazing to work with. The staff is super friendly and what they charge for labor is very reasonable and fair. I've called 4 different places to install my race exhaust. The shops quoted me around $600-$800 for labor stating that it's a 4hr job and that I must leave the vehicle. One shop (Porsche Service House Pasadena) quoted me $1200! If I had a lift I could have done this myself. It's a MAX 2 hour install job. They wanted me to leave the car so they can tell me it was 4 hours and charge ridiculous charges. Supreme quoted me $350 and finished it 1hr and 40mins. I made an appointment and they were able to work on my vehicle right away, very efficient. Will (mechanic) even took out a measuring tape to make sure my exhaust tips were sitting even. Perfect for someone extremely picky like me. They are car enthusiasts that value customer service and do not take advantage of their customers. Highly Highly recommend them read more

These people definitely set a new standard for me in terms of both car care and knowledge as I felt my car was in good hands the entire time. I encountered literally 0 problems while I was there and I can only say amazing things about Supreme Power. I was in search of a reputable service center but I want nothing short of the best, which is ultimately what led me to meeting Kim and Juan, two people I felt were genuine and honest which is a trait that I don't come across a lot when it comes to some of the 'other' places. Prices are great, service was exceptional, and the location/service area is literally flawless. For a car enthusiast, there really isn't a better place for both service and aftermarket installation in my eyes. Highly recommended and then some. Thank Kim and Juan! Appreciate you both. read more

Eric and Kim have worked on every car that I have owned including my S4, M4, Range Rover sport, Range Rover SVR, Tesla, and now my Bronco. They are great about helping you figure out what will work and what won't and they never hesitate to help with you crazy ideas. And equally important-they always get you a great deal. Most recently they installed KW V3 coil overs and HREs on my Tesla and then corner balanced it. Handles like a dream! I look forward to seeing what we can do with the new Bronco. Don't hesitate to check out Supreme! read more

The guys did an amazing job dialing in my alignment for my track day at Auto Club Raceway!

If you're looking for a shop to get it done right, with the customer service you'd expect, for a fair price this is the place. Took my BMW X6 in to get new tires and I felt well taken care of the entire time. No more searching for a performance shop for me. read more

I'll keep this short, simple and to the point. Best prices on WORK SP1 after comparing different vendors (thank you, Eric). Great Customer service and hospitality (thank you, Kim) Will return for future projects. read more

I had coilovers installed on my 2022 Subaru WRX at a different shop and I was in need of a alignment. Its hard to find shops with a in ground alignment rack and technicians who know how to properly adjust the alignment using aftermarket parts. Luckily I found Supreme Power and I'm glad I went. The shop is immaculate and the employees are very helpful. I was not looking for an aggressive track alignment, but they do know how to. I'll come back for more work in the future. read more

Thumbs up .. read more

Kim and Eric have always been on top of their game with all of my cars. I would recommend them! They have worked on many of my cars over the last decade. Always a good experience. read more

This review is overdue, but at least I can give an honest review based on a good evaluation of the installation a few months later. This place is the best! I took my Boxster to them to get it lowered after contacting them via Yelp. They responded to my inquiry in quick fashion and gave me an estimate based on my request. I made an appointment and was able to get my lowering springs installed and six months later, I'm still enjoying the improved stance of my car with no issues to report. The employees were very nice, and they even undercut my regular mechanic on the install cost by a LOT! I highly recommend this business because they obviously know what they are doing and treat the customer right. I look forward to having future modifications handled here. read more

Needed alignment and was extremely pleased. Great customer care with Kim to schedule and Will did masterful job. Great work. I'll be back.

It all started back when I got my first car, a BMW E30 when my hobby with modding cars started. I grew up watching my uncle mod his own P cars from his 914 track car w/ a 993 3.6L to his 996 GT2. Modding which included doing his own motor swaps and other sorts of more in depth jobs I wish I knew how to do myself. First met Eric back around 2001 when I first got my s4 and was looking for parts to begin modding it. Back then Eric specialized mostly in VAG cars and through the years has built up a very nice clientele list ranging from VW's all the way to Ferrari and everything in between http://www.yelp.com/biz_photos/3DfBllgXZaJD8lMDzdhojA?select=UnU2GC_B-45FoVfQh7fEVg#S6LSD1cIZ3BlmPPT5TOu9w. Glad he still has time to serve the lil people like myself. It was time for new shoes for my daily and knew who to contact http://www.yelp.com/biz_photos/3DfBllgXZaJD8lMDzdhojA?select=UnU2GC_B-45FoVfQh7fEVg#F1Ptdkx9HF8jaRoFZMkUUw. Provided Eric with exactly what I wanted and the tires were delivered in less than 2 days. Was in and out in less than 30 mins. Couldn't be happier with my purchase and it's always reassuring to know that SPP offers it's clientele the best pricing along with the best service in LA. read more

Extremely disappointed with how things turned out. You trust someone to do a good job and be honest. You pay them in full expecting good work. Instead the did body work they did for a body kit install was a very poor job and ended up PUNCTURING the turbo hose on my Audi and ruined it. Had a check engine light nightmare, etc etc etc. Unfortunately, too much time had past and they wouldn't take responsibility for it. Won't ever go back. read more

Its important to leave an honest review for a business that you spend quite a bit of money on. I emailed Eric back in June for a set of BBS wheels I had in mind for my GT3 RS. Eric was super responsive, answered all my questions, sent me many pictures and videos of different finishes. It really helped me decide what I ultimately want to order and how I wanted my wheels to look like in the end. After I sent the deposit, a week later my wheels were completed with my custom finish. Unfortunately the finish was not done to the standard that Supreme and I could accept. They immediately sent it back, and promised to make it right. I own a few businesses, so I know things go wrong. Eric made it right and packaged the wheels very carefully when they came back. They mounted the tires I ordered as well, so nothing but putting on the wheels needed to be done. I really appreciated how the process went, even with some bumps on the way. The wheels look amazing, and I could not be happier with how the look on my car. I got a great deal on the set with tires through Eric as well. I will absolutely order more modifications over the years through Supreme. read more

I could not recommend Eric or his team more highly. They are the most incredible, thoughtful, kind, personable, approachable and knowledgable company I've ever dealt with, and as a result I'll never ever use anyone else ever again, despite the fact that I'm based in the UK. Customer service such as this is beyond rare nowadays, so to discover an organisation that goes above and beyond all expectations regardless of your needs is both precious and fantastic. They are a shining lighthouse in a sea of broken bulbs. I cannot commend Eric and his organisation more thoroughly. I've given five stars above as that's all it'll allow, but if I could I'd give a million. read more

Supreme Power is best in the biz. The only place I trust mounting tires. Custom wheel builds are their specialty. Eric is most definitely the number one bbs wheel supplier amongst other brands as well. read more

As a first time Porsche owner, I spent quite a bit of time talking to several different shops around Southern California as I wanted to gain confidence in making sure the right shop works on my car and answers all my questions without hesitation. Without a doubt, Supreme Power was the best shop to work with as both Eric and Kim answered all my questions quickly and were straight forward and reasonable with their pricing and availability. This is the only shop that has also provided me with a loaner vehicle so that I was able to get back to work while my car was being worked on. The shop is absolutely incredible and spotless both in the front lobby as well as where the work is performed. It is immediately clear from speaking to everyone at Supreme Power that they take pride in their work and are passionate about what they do on a daily basis. Needless to say, they have a customer for life and will be working with them in future as I get more modifications done for my 2017 911. Below is a picture of the work they performed on my car dropping it on H&R springs, installed spacers, and alignment performed. read more

I went there to do ONLY 1 tire change . the customer service was just ok. And I was asking can they do it will-in an hour since I only need to do is 1 tire and the guy was refuse to say yes cuz he reasons was many people in front of me but in fact only 2. It took 1 hour and 20 mins to complete . The worst part is I Can't believe they left the hood open and didn't close it and gave Bk the car to me and say it's ready to drive. I didn't find out until someone was nice enough pointing at my hood and told me it's open. When I found I was so mad and disappointed by their service. And I'm shocked they didn't care enough to close it . I will NOT recommend this place at all. So unprofessional. read more

I'm extremely satisfied with the service and knowledgeable staff,professional and honest .

Splendid experience getting new tires installed on my E92 M3. Spoke to Kim in the morning. She was very receptive, genial, and absolutely helpful in scheduling an appointment the very same day. I brought my own tires from Tire Rack but wasn't sure what to expect from their mobile installers, so I went with Supreme Power after a quick search and found them to be exactly as advertised. They are professional, prompt, and deliver as promised. Cleanest shop I've ever been to! Kim was awesome and made sure I was comfortable in the waiting area. I'd go back again! read more

Supreme power is an awesome shop with good prices and the quality of work is second to none.

First time Porsche owner here. 991.2 GTS. Eric, great guy and help me secure a Kline header system at fair price. I had a second hand Kline exhaust system I picked up and he agreed to install it. The price to install the full exhaust system and the headers...such a great price. Kim, she's great. Easy to talk to, helpful in every way. She allowed space for me to do work on my laptop and it felt like I had an office there. Will the installer. Quiet at first, all about his business. Really cool guy. Ran into some issues upon install, and he was very concerned for the integrity of the car, safety of me the client, and his company he works for policy. I was hoping this second hand purchase wasn't a regret. Collectively myself, Kim and Will figured the problem at hand and he successfully completed the installation. Appreciate Will not giving up. Make the hour and half drive home much better. Thanks again all, can't wait to be back for the header install. read more

Tried calling this place to get information on Unitronic I was told by the girl on the phone she did not know anything about it and that their guy is the one I need to contact so she gave me his email. In my mind this is your business why don't you take a message and have who ever then contact the customer that will provide a better service experience for your customer all her attitude showed me is that she does not care for my business nor do I want to give it at all to supreme power. First impressions are everything you failed read more
