I brought my 2020 Shelby GT500 Carbon Fiber Track Pac in to upgrade the super charger lid with a VPM performance lid, and also a resonator delete. They did a great job! Planning on coming back to do a pulley swap and custom tune. Stand by for my next review.
Glenn and his crew at RPM are flat out amazing! They did a tremendous job with my truck. They’ve been up front with my build and helped me to get going in the right direction. During the initial phase of my build I ended up changing some things and adding other items which Glenn and his team were able to incorporate smoothly.
Having my truck back this weekend after the initial build phase was eye opening, the truck was awesome already but the performance parts, tune and TIG welding they did were all too notch. Really really impressed and beyond happy with the results! These guys are awesome!!!
These guys have made my dream car a reality, and I have nothing but incredible things to say about Glenn, John, and the rest at RPM. They do incredible work in a timely manner and are great at communication. They’ve always been honest with me and have led me in the direction that I want to be with my car. I love this place and wouldn’t bother going anywhere else. Visit these guys with 100% confidence. Best shop in town and if you want it done, they’ll do it! From interior to exterior mods, engine performance, and everything in between, they’ll take care of you! Thanks for everything
You can't doubt the quality of the work they have. Although by the time you get your car back you will wonder if it ever was worth doing business with them. They will never answer any calls or respond to emails. If they tell you that they need your car for two weeks, then be prepared to keep your car there for a month and a half. Also, if you plan on having Glenn work on your car, never take him for his word, be sure to have everything documented and any guarantees in written form because he will not keep it. (EDIT) Responding to the reply by the owner, this review was written after many people kept asking me about the garage and what I have written in this review is what I have told everyone. Additionally, the owner says he gave me a discount on the parts. The work done on my car cost $13000 for a 392 heads and cam package, that price does not seem like a discount.
All I have to say is"DAMM". Glenn and his guys have built such a well-balanced power package for me. The car is surpassing all of my expectations. His expertise and knowledge of cars should be listened to, plus the quality of the work is excellent. I look forward to the future of my current car and next project with RPM.
I had my 2015 Jeep Grand Cherokee 5.7 serviced by RPM, with Kooks catted headers and Borla exhaust swap alongside a PCM tune. The setup unlocked an additional 40hp and a much smoother dyno curve that can be felt on the road. They delivered on a few other misc requests, like the installation of a set of Morimoto headlights and a Chief Products roof rack. Really happy with the results, expect nothing but the best from RPM.
My motor blew in my 2018 Jeep Grand Cherokee SRT and I was lucky enough to have RPM do my motor swap for me. They worked really well with my extended warranty company to get everything covered. Working with Devan at the front desk was awesome. He updated me with what was going on with my car so I never had to worry. I got to meet the owner, Glen, he was super nice. He took the time to come out and fill me in on what took place before I drove off with my new motor. I couldn’t help but to notice all the Mopar cars they had out front. If you ever need any warranty work done or mods on your car I highly recommend RPM! 10 out of 10 for me. Thanks guys!!
I recently had my car's brakes serviced at this shop and I couldn't be more satisfied with the results! From start to finish, the team was extremely professional, knowledgeable, and efficient. They took the time to thoroughly inspect my brakes and explained everything to me in detail before beginning the job. The quality of their work was top-notch, and my brakes now feel better than ever before. I was impressed with their attention to detail and commitment to ensuring my safety on the road. The entire experience was hassle-free and stress-free, and the pricing was fair and competitive. Overall, I highly recommend this shop to anyone in need of automotive services. Thank you for your excellent work and outstanding customer service!
