I had Paul guide me through the purchasing process for my Audi RS3 on the FB group page. I wanted 18's different from the OEM 19s with a more meaty trie setup. It was a difficult decision when one of the wheels choices was BBS LMS but decided to go with some WedsSports TC105X. The wheels did not disappoint and they're about 16/17 lbs per wheel. Overall, great customer service via FB chat and at the shop. Loading was a breeze which of been but took some time admiring all of the yellow Porsche. Such a beautiful line up! Great experience overall and maybe the BBS LMS will be my next purchase. read more

Excellent shop if you care about your wheels staying pristine. Their touchless tire mount machine and skilled techs give you peace of mind knowing your rims won't get scratched. The in-floor alignment lift is a huge plus for lowered cars, and you can have your setup dialed in to your specs if you know what you want. Wouldn't hesitate to bring any of the other cars in for the same. Look forward to meeting Kenji soon. read more

I've always trusted Supreme Power with all my vehicles. The owner Eric is extremely knowledgeable and super competitive when it comes to pricing in his market. There's nobody in SoCal that comes close when specializing in Euro and Super Cars, wheels and tires, and the aftermarket fit requirements that go along with them! Check him out, you won't regret it! read more

I've had the pleasure of watching Super Power grow from a small space back in the early 2000s into the well established shop it is today. Their growth has been nothing short of impressive. What sets them apart is not just the outstanding customer service, but also their ability to source some of the hardest-to-find aftermarket parts. I personally know some of the techs, and these guys have been in the industry for a long time. They've worked on just about everything from daily drivers to high-end luxury cars and even supercars always with the same level of care and expertise. Eric and his team really go above and beyond to make sure every customer is taken care of. Whether it's a small upgrade or a major build, you can trust that you'll get honest advice, quality work, and a shop that stands behind everything they do. Super Power is truly a gem in the tuning community, and I can't recommend them enough. read more

Supreme Power - BBS E88 that Eric from Supreme with perfect spec set up. - Auto Customization Near Me - Fullerton, California

had an outstanding experience purchasing a Kline exhaust for my Spyder RS. From start to finish, the entire process was professional, seamless, and confidence-inspiring. The team was exceptionally knowledgeable about the product and took the time to answer detailed questions about materials, fitment, sound characteristics, and performance implications. It was clear they understood both the technical side and the enthusiast perspective, which made the decision easy. Shipping was prompt, packaging was meticulous, and everything arrived exactly as described. The installation fitment was precise--OEM-level alignment with no surprises. The quality of the craftsmanship is immediately apparent: beautiful welds, premium materials, and an overall finish that reflects serious engineering discipline. Most importantly, the exhaust completely transformed the car. The tone is sharper, more exotic, and far more engaging, especially in the upper rev range, without introducing unwanted drone. It enhances the character of the Spyder RS rather than overwhelming it. I would not hesitate to purchase from this company again. If you're considering a Kline system, this is absolutely the place to buy it. read more

Eric is super friendly and accommodating. Supreme Power did a small upgrade for my exhaust 1-2 years ago and I noticed, the tips were sagging.

Okay so I'll keep this simple. I had a BBS wheel project I needed done right and a friend pointed me to Supreme Power. Best decision I made. Eric and Kim are the real deal. They responded to every message I sent basically immediately, kept me in the loop the whole time, and somehow got the wheels done faster than I expected without cutting a single corner. The finished product is absolutely immaculate. Also their shop is literally like a candy shop if you're into wheels. I could have spent hours in there. These two genuinely care about the work they do and it shows. High end wheel needs? Don't overthink it, just go here. Already planning my next visit. read more

Outstanding customer service! Very professional with exceptional response time. Extremely knowledgeable with the products they sell.

Only great things to say about Supreme Power. Paul is the authority on wheel fitment for Audi TTRSs and RS3s. He was able to provide the perfect wheel and tire specs and get my dream set of BBS wheels ordered. Kim got my order handled and sorted logistics details, and Eric reached out to me (as I asked) and confirmed timing/details prior to shipping. The wheels showed up exactly when and as promised. The whole Supreme Power team was fantastic. Would absolutely work with them again for any wheel needs. read more

I had an outstanding experience with Eric and Kim at Supreme Power. After purchasing a set of E88's, the team went above and beyond to make sure I had everything I needed for installation when I received them in Florida. When a local installer caused issues with the setup, Supreme Power didn't just wash their hands of it--they had me ship the wheels back, inspected them, and remounted/rebalanced the tires which resolved the local installer's faults. They ride perfectly now. Truly elite customer service and integrity; they stayed patient and ensured I was 100% satisfied. Highly recommended! read more

My experience with Eric and Supreme Power is so wonderful! Amazed my the above and beyond from Eric for the service provided.

Can't thank you enough for getting me the brand new set of BBS Manthey Racing Motorsport Gold Magnesium wheels for my 991.2 GT3RS. Looking forward to sharing pictures with you soon! read more

This review is long overdue. To start off when you take your car to Supreme Power, you leave knowing that they are going to do an excellent job!! I've been coming here for years, Eric, Kim and Henry have been helping me get my Porsche 911 dialed in. The Attention to detail is what I love the most about this shop. Back when I ordered my set of BBS wheels from them, Eric (Supreme owner) thought the car would have a better stance if we had some spacers in the front to have the wheels sit flush with fenders. Eric special ordered set for me and installed them free of charge. I was really surprised on how much they care about their customers leaving completely satisfied!!! Supreme takes a lot of pride in quality and craftsmanship so you'll leave knowing everything was done the right way! Highly recommend this shop to anyone that has a high performance car. read more

Just wanted to thank the team at Supreme Power for going above and beyond in helping me with my wheels. I have a Porsche Turbo and wanted a set of BBS E88's with a very specific look and stance. Eric assured me from the start that he would make sure I was 100% satisfied--or I wouldn't be obligated to buy. When it came time to mount the wheels, the lips weren't exactly what I had envisioned. Without hesitation, Eric told me to come back the next day, and he had the wheel lips enlarged perfectly to match what I wanted. That kind of extraordinary customer service and attention to detail is rare to find. There are very few shops willing to invest the time, money, and effort to ensure that every client leaves completely satisfied. Thanks again to Eric and the entire team at Supreme Power--I couldn't be more thankful! read more

Kim and Eric at Supreme have been working on all my family's cars. Their work and customer service is and has always been amazing!

Supreme Power is the BEST wheel shop in the greater OC area. The owner Eric and his staff are super helpful and walked me through the entire process of picking out the overall best BBS wheels for my 991.2 and took really good care of me on price. The team at Supreme has helped me get several rare BBS wheel sets over the years. They are super knowledgable and experts in the wheel game. HIGHLY RECOMMEND! read more

I had an awesome experience ordering a Kline exhaust through Eric at Supreme Power! From start to finish the communication was fantastic -- Eric was responsive, clear, and helped answer every question I had. Pricing was very good, and the whole process was smooth. The initial timelines provided were very accurate, which I really appreciated. The exhaust was very thoroughly packed and arrived without any damage. Great service, great people, and I'd absolutely shop with them again! read more

SPP is the best aftermarket installer I've used. If you have a BMW, Porsche, etc., definitely run to them for any of your aftermarket needs (wheels, suspension, exhaust, etc.). They can do literally everything, at fair prices and with excellent service levels. read more

I had an AWE Track Exhaust installed on my 2021 M340i. When they installed it in March 2024, I noticed rattling within a few weeks. However, their installation tech told me to ignore it and said it was normal after I brought it in again for them to check. Fast forward to today, the exhaust heat shields, connecting member rear tunnel and center mount exhaust bracket are damaged (about $700 to repair). A different service shop was the one who noticed this, and pointed out that one of the bolts were cross-threaded and the exhaust was mounted too low when they put the car up on a lift during my routine maintenance. I sent the pictures of the cross-threaded bolt, as well as the rest of the damages to Eric and his team, and they said since I was past the 1 year warranty they wouldn't help. The pictures I showed Eric show very clearly a cross threaded bolt, which lead to the rest of the damages. They even stated that over a year of driving could have led to other things damaging the heat sink and bracket, when clearly the damages are all caused by a rattling/improper exhaust install. They said if I had brought it in within 3/2024 and 3/2025 they would have covered the damages. However, why would I bring it in a 3rd time for them to check, even when after their installation tech heard the rattle himself, and said it was normal? Also makes me think even if I had brought it back in within the 1 year warranty period they still wouldn't have covered the damages... I understand businesses can make mistakes, but they should be judged on how they respond to them. Eric and his team's response clearly wasn't great, and I'm confused how they can be so reputable in the car community if this is how they conduct business. If you're considering going to Supreme Power, just don't. Message me here and I'll give you the contact info of the store that found out these damages for me. This store offered to not charge me the labor needed to fix the damages and only pay for parts. They truly have a love for the car community unlike Supreme Power. read more
