For the last several years I have been coming back to Griffin Motorwerke. Not because Curly and Terry are fantastic people who are fun to talk about performance upgrades and other gear head stuff, and not because of their unmatched knowledge about VW/Audi/Porsche/MB. And not because of their amazing new repair facility, I keep coming back because of the whole package. They have done wonders to fix many cars I have owned, including a Hyundai Tucson and Subaru WRX. More importantly, they also built my Audi B5 A4 from the ground up, complete with mods, and they continue to work on that same car for the current owner! Recently they took my MK6 GTI that had a problematic stock clutch, that started slipping at 16K, researched the best solutions for repairs/upgrades, and then installed a new SPEC Stage 2 clutch and Wavetrac LSD. I have to say that I am excited to go back for the next round of performance mods! Griffin Motorwerke is a fair, honest repair/upgrade shop. The prices are competitive, and the mechanics are fantastic. You would be hard-pressed to find a comparable shop in Northern California.
