I’ve been to Griffin with two of my BMWs a 05 330 with a full coil over set up that they dialed in and sport tune aligned. felt really good with spirited street driving and light tracking. And my 09 335I that they did a sport two and alignment and wheel balance on with m3 control arm upgrades and sport struts, previously installed. feels great, just how it should better then the day I bought it. Their customer service is upfront and really friendly they got the work done in a timely manner as well. will be going back next time I need suspension work.
