Flawless install of Stage 1 Mountain Pass sport coilover kit and rear camber arm on my Tesla Model 3. Quick install and street alignment got me set up for some canyon drives. They are real pros who usually work on high end european/track cars, but are also the top Tesla suspension garage in north county. Thanks!

Always top notch works from Omar and the guys! Just had them install a Sharkwerks exhaust on my 992.2 GT3 and they did a fantastic job!

Anthony and the team at HG has been amazing to work with and they were very helpful. I enjoyed my experience with HG. They performed a series of upgrades and maintenance on my X3M and I am very stoked on how the car is performing.
