If you're in the aftermarket automotive industry you probably know Eric @ Supreme Power or have dealt with him at one point or another. This is the go-to shop I send all my friends to in Orange County. He can get anything you can imagine and get it quickly. There are a few overseas only parts that Eric has successfully been able to source for me. He is very knowledgable on pretty much any car you throw at him and his experience puts your mind at ease when it comes to modifications. He is a huge car guy and his personal cars shows great taste in modifications. Whether its your first car or your 50th car Eric will point you the right way. I've had him install countless sets of tires on expensive forged wheels and he's never damaged a single set. He's ordered a few sets of Brembo BBK for me as well and KW coilover in the last few years. He's always given unbeatable pricing and he gets the products quick. I mean they're not just your typical shop, these guys are your one-stop shop. From wheels to suspensions to exhaust to bumpers, spoilers, wide body kits, etc etc etc. Talk to Eric, you'll be happy you did. read more

1. Excellent Service 2. Kind Staff 3. Helpful Owner 4. Great Shop 5. Amazing people Supreme Power Parts has been my go to shop for the past half decade and I have had nothing but great experiences working with Eric, Tam and the other members of their staff.

Would recommend to any and everyone to try out Supreme Power once. You will not regret it. - B read more

I took my 458 spyder here to fix a tire that another shop had failed to repair. Supreme took good care of me and fixed my tire with no issues. Very knowledgeable staff, great customer service, and very honest and upfront. I will be taking all my cars here from now on for my automotive needs. Check them out for yourself. Highly recommended. read more

This place rocks!!!!! I came here after when my cousin Kendo got me "hooked up" with the owner here. Got me a new set of Brembo 14" for my z and he installed the calipers, rotors and lines all within 30 minutes for both sides!!!!!!! Price was beyond excellent and I even had to tip him $100 cause he was getting slack for being late at a wedding reception he didnt want to go to..... Wanna give your ride that extra "oomph?!" call these folks up and they'll treat you royally. read more

Couldn't be more satisfied w my FI-R rims and choice of light weight tires. Only took a week to order and another week to be scheduled for installation. I was quoted 6 months wait order on the rims from another tire n wheel shop, but with some research, not all shops are on the equal level at all. read more

Give these guys your money. Now. They turned my Pinto into a Pantera in a matter of days. AMAZING! read more

Was able to stop by the shop today and learn about the different exhaust options available for the Porsche 991 Gt3. The sales staff was helpful in showing me the various exhausts and allowed me to hear them in person. I find Supreme to listen to my needs and provide me a tailored solution as opposed to selling what makes them the most money or furthering their own objective. Would definitely recommend to anyone who values top notch service and very fair pricing. read more

These guys are awesome (and their dog too). And real nice. I had a wheel imbalance which was causing vibration and they fixed it with a proper balance. Which is a major relief after the headache I went through with the shop that mounted my tires. They also worked through a stripped lug and was able to get me replacements in the shop (oem g37) Def would recommend. read more

Supreme took care of my BMW M3 for years. Very professional staff, very knowledgeable mechanics who can do anything A-Z aftermarket that the dealership won't do. read more

Been coming to Supreme for years. Great products with quick professional advice and service. First with multiple M3's, recently with my AMG. Just picked up a daily driver A4, going back soon for some BBS wheels. Best around for fitment when it comes to aftermarket parts. read more

Eric and his team are the best. Been a customer for almost 15 years and I wouldn't go anywhere else. Amazing to see how large the company has grown over the years but Eric still always provides personal service, knowledge and wisdom to each customer. 2 thumbs up!! read more

Just got my HRE wheels and suspension installed on my G80 M3. This is now the 5th car of mine Supreme has worked on. Obviously, it begins with trust, quality work and professionalism. That's what makes me keep going back to Eric and his team. They know what they are doing. And most importantly, the entire Supreme Power team (Eric, shop manager Kim and the install team) treat their customers so well! Will always be my first call for any work on my cars. read more

Have been going to Supreme Power for years. Always great customer service, able to source the best parts, work is always done in a timely manner, and also the cleanest and best garage in SoCal. Highly recommend read more

Great place. Very knowledgeable and fantastic customer service. I've never been disappointed with their work. Highly recommend

Came in for some new wheels for my M4. The guys were cool and hooked me up with a good price for the tire and wheel combo. Had a little problem with a valve stem leak when i left, so i had to run all the way back to have it fixed, but they did it graciously and even had their detailer give my baby a wash. Eric was super helpful. I'll be back. read more

Supremepower isn't just an autoshop - they're automotive experts. I recently purchased a F82 M4 is Black sapphire metallic, and was cruising through the forums to find my first mod. I shopped around, and got in touch with Tam and Nick. Both were very easy to work with, and put together a wheels and tire package for some satin black BBS FI-R. The wheels took 3 weeks to deliver, but Nick kept me updated along the way. I got picture messages of my tires and rims when they got in, and a courtesy call to schedule an appointment. The install was straight forward. They bagged my OEM rims and carefully loaded them in my trunk. While I was there, I decided that I wanted to change out my OEM kidney grill surrounds, and they accommodated me right away. Everyone in the shop is an enthusiast. That made for some great conversations, and lead to a passenger ride along in the supremepower f80 M3 to help me get a feel for what coil over suspension I wanted. I had initially planned that my car would remain "stock" for a few years, but threw that all out the window once I rode around in their car. I told them to take my money now. Looks like I'll be back. Thanks again to Tam, Nick, and Justin for an awesome experience at Supremepower! read more

Wanted to put an exhaust on my Jetta, I was referred to this place from AWE tuning. Ordered it and got it installed in 2-3 weeks (super fast) and I love it!! Owner let me pay half to start and the other half when I got it installed. Everyone was super cooperative and really nice. I love this place and will definitely come back if I add some other mods to my car! 110% recommend to anyone. read more

Supreme Power is always #1 in my book and I wouldn't go anywhere else. I have been going to them for almost 10 years now and every time Eric and his team are always professional, accommodating, true pro's at knowing exactly how to custom fit your aftermarket parts and Supreme's prices always beat out the competition. Always a pleasure gentlemen! read more

These guys are true professionals. On top of making the right recommendation, they have great prices, a huge selection of parts (both oem or aftermarket goodies), and Eric and his staff always go the extra mile to making their people happy. All the rave reviews are not just propaganda...these guys are the real deal! read more

Very very happy with the service I received from the whole team at Supreme Power. Kim, Eric, and their technicians are truly a class act! Hands down the best shop I have been to in my 12 years of upgrading my cars. Eric was brutally honest with me (which is uncommon with shops), and told me what I did and didn't need for my car. He dialed in my Porsche GT3 RS better than I could have imagined. If you are looking for an honest, reliable, and reputable place to take your car, don't look any further than Supreme Power. I can't tell you how many horror stories I have had with other shops. It's nice to finally have a good home. Thanks Supreme Power! read more

I had the best experience with Supreme Power. I was referred to them by a member on a car forum, and although they were almost a hundred miles away, I'm so glad I went. Their shop is clean and well kept. The owner gave me a quick tour of the facility and boy, do they have some cool toys in for service. They installed full suspension on my M3 and I couldn't be happier. One thing I really appreciated is that they stock/order all the necessary parts. It's the perfect "turn-key" solution. I explained to them what I was considering, my goals, and they made suggestions. It was as simple as "I want my car to be X, Y and Z", and they said "That will be $XXX.XX". B-E-A-U-Tiful. Suspension was installed, corner balanced and aligned. Thanks for all they work! Can't wait to go back. read more

Nice to work with honest shops! Ordered parts and installed in and out in less then 90 mins read more

See all

Had i knew how awesome SupremePower's service, the people who work there, i could have gotten my exhaust and GIAC from them instead of the closer one from me in West LA which is a shop near IKEA in Avalon. Eric gave me a sweet deal on the BBS CH-R, way better deal than anyone else selling it including TR. Damian, took really good care of the tire install. sanded the rust on the wheel hub then spray painted it black. never experienced a wheel shop ever do that. Nick who was the first guy in the morning, had awesome customer service when i arrived and so did Tam. I don't mind going here driving in traffic for an hour from West LA. the trip is worth it. I'll be coming back. Thank you SUPREMEPOWER! read more

Came here to get my BMW F30 lowered and aligned. Stefan and Andrew were awesome in working with me and Andrew was the man in getting the job done right. The shop is absolutely pristine and I will definitely be coming back to get more work done. Best of all, they're extremely reasonable in their pricing. read more

Supreme Power and Eric the owner is the best in the business. My 2017 Audi RS3 came in for wheels, exhaust, suspensions. Let's start from the very beginning, I love cars but have very limited knowledge of upgrading cars, Eric spent so much time explain every little stupid questions that I have and help me built a list of things we can do to the car. Everything goes so smooth and on time. I never write any yelp reviews, but if you are in the market for any car related needs, I would totally recommend Eric and his shop. I will definitely bring all my future vehicles here direct from the dealership! Thank you so much Eric and supreme power for an outstanding service and experience. read more

The guys at Supreme are awesome to work with. Listen to their customers needs, focused on a positive experience with great products and prices! Wheels, Tires, Suspension all setup without a glitch!! Thanks read more

Revised Review: After frustration over a miss-installed bumper grill, Eric exhibited excellent customer service and made me a offer to get a free oil change, processed refund, and offered to help in discounted future installations. Eric, thank you for caring. I will return to Supreme Power. I revised my rating to reflect this. Initial Review: I took my Porsche 911 Carrera S to this place to order and install bumper grills for my front bumper. Initially, the guys were helpful. I asked them whether they have done similar work on a Porsche before and they simply downloaded a photo online (from Rennline) and sent to me claiming that it was there work. After they finished the work, washer hoses were hanging out from inside and not installed properly. I drove off and saw the issue a day later and had to bring it back in. The guys had to tuck it from outside in with a piece of metal, totally not the best way to handle a Porsche. I have experienced poor quality control at this place that ensures service is delivered with the highest quality. This was not the only reason for my OK review. The guys initally recommended that I also install the middle grill (not only the sides). I asked them several times whether it will fit, and they confirmed. I bought it based on their recommenation, and when they attempted to install, it did not fit. After four months and several attempts to contact them for refund, they refunded the cost of the extra part. I wanted to have them as my place of choice for oil change and other body work, but I'm not convinced of their top notch service based on experience. I am a perfectionist Porsche owner that does not appreciate half-a** work, poor follow up to customer requests and e-mails, bad quality control, and lack of knowlege on the product. read more

From start to finish the most incredible automotive experience I have ever had. I went in for a simple set of wheels and lowering springs and Eric and Kim bent over backwards from the design of the wheels to answering all my ( hundreds of ) questions it was outstanding. I will most assuredly be back for all my automotive needs as this place is not an option it is the industry standard. read more

Eric, Stephan and Ben (Mops) are extremely knowledgable and helpful. They were able to install wheels, an exhaust and a front lip for me the week before I was moving out of state. They are prompt to e-mail back answering any questions you have. Highly recommend them! read more

Was seeking out a new exhaust system for my S4. Had posted about it on the forums. Cameron sought me out and offered a tremendous amount of help. I ended up actually buying a conversion kit for my current AWE performance exhaust and saved tons of money as opposed to buying a whole new system (I did not even know a conversion kit existed). To top this off, Supreme Power was not only able to match the lowest price I was able to find online for this conversion kit, but they actually were able to beat this price. Very pleased with this experience and the overall responsiveness of this business. I will definitely be using Supreme Power again in the future. read more

Eric and his team have been taking care of my car since I got it. They've done complex suspension work, wheels and more. His team has always been on point and attentive to addressing all my questions. His pricing is fair and he'll go the extra mile to make sure you're happy. The new location is impressive and I continue to bring my car here for work. Highly recommended. read more

These guys are just okay, not great. I specifically brought my brand new enkei wheels here to have tires mounted because of the touchless mounting machine they have. Well, it didnt matter because they managed to scratch 3 of the 4 wheels anyway. One deep gauge on the spoke, and two wheels chipped around the center cap (probably from putting it on the balancer without care). Charged 120, which was a little on the high side, especially for the conservative sidewall (45 on a 17 dia). Overall, I expected more, but couldve got the same service at any regular tire shop. Woudve given 2.5 stars if that was an option. Wont be going here again. read more

Supreme Power has been helping out my family and I since our first M3 in 2002. Fast forward to present-day 2015, they are still helping us choose excellent products to modify our cars with. We've had over 5 of our own personal cars done here and they all turn out perfectly. If you're debating on any aesthetic modifications, definitely consult with Supreme Power before doing anything. Installation is always done promptly and product quality is always excellent. There are never any frills with the process - it's just simple. Other shops should take note on how Supreme does their work. read more

I've trusted Supreme Power with my cars for the last 20 years. I even went So far as to send my brand new M3 across the country to them for a full build. Eric is amazing and has always gone above and beyond for me and my vehicles and I never hesitate to recommend him and his team to my closest friends. read more

Eric was great the whole way though the transaction. He. Took the time to answer all my question on the phone and though email. Once he made the sale he took the time to follow up and make sure I got my parts by the date I needed. When a problem came up with getting me the resonated system I wanted for my car he came up with a solution and was able to get them to ship me the rear section of the exhaust and got Millteck to send the resonated section to the installer so I would have it in time. Thanks for the great customer service and follow though! read more

When I needed to get stupid with some 20" HREs Supreme were the only people I needed to call, they're the best!

First time to be here, Armand, the red devil mr2, referred me to this place. i came with 1 wheel and 1 used falken tires. After a while, they told me the tire is bad and it wont stretch out. i was going bananas cuz i bought 4 used tires. **pardon me for my baller-under-budget**. so i figured i have to pay for the installation cost, but they said "dont worry buddy, u good to go". i felt bad for wasting their time. Then they invited me back to the garage and Eric showed me why it won't stretch out in detail. Then he went to the used tires storage and found a used Falken, just exactly my size and mounted it. Eric & Tham is really nice & friendly guy. I definitely will come back read more
