Griffin Motorwerke ar so professional and now I'm a customer for life. Griffin did a splendid job upgrading my Macan GTS with a Cobb Stage 3 Power Package. Not only was the install done perfectly, they also fixed an inherent problem with the Macan aluminum valve cover bolts which shear off at high torque demands. They replaced the aluminum bolts with stainless steel ones. Problem eliminated. The Porsche Macan now has a deeper voice, snarls on startup and growls when prowling down the street. My neighbors love it too! She's peppier, responds quicker and is just overall a very different drive experience. Thanks to all the folks at Griffin - great job!

Griffin Motorwerke installed Mountain Pass Performance Comfort Adjustable Coilovers for us. They communicated well and made it convenient to drop off and pick up our Model Y, which could have been a pain because we live a few hours away. The coilovers made a huge difference and Griffin dialed everything in nicely for us. Ripping back up 80 into the mountains was a joy and the suspension tightens up well at speed while dampening the vibrations coming off rugged California road surfaces much better than the stock suspension. I highly recommend working with Griffin for all your Tesla upgrade needs!

I always receive fast professional service at Griffin.. Curly and Nate et al have the shop running smoothly and following perfect COVID protocols. When I brought my car in it was running so poorly I had already started shopping for a new car... I left with my car the very next day it was running like it’s new!! Thanks guys! I’ve already told all of my friends about the service at Griffin, now they will hear it again..

Having a broken car is no fun. But, Curly and the crew at Griffen do their best to get me in and out as fast as possible with the appropriate work preformed.
