Took my Cadillac ATS-V here after the dealer and another shop couldn’t track down my problems. Rick was super helpful, they really had great customer service and are my new go-to shop. The work they did was excellent and I am eternally grateful that I found this gem of a shop. Can’t wait to have more work done... read full comment

Rick and Kyle did a good job installing coilovers, toe rods and subframe lockout kit on my camaro; and setting the ride height to my preference. I couldn't be happier with the outcome. I appreciate their expertise, attention to detail, willingness to discuss options and share their knowledge. I'm happy I found them.
