515 Motorsport has been amazing, every time! I trust their honesty, integrity, and quality. After buying an older BMW, the people at 515 went over the car with a thorough inspection - Greg and Paul have found missing washers, loose bolts, failing suspension components, leaking valve covers - among other things. AJ and Justin mocked up, fabricated, and installed a new custom midpipe - while Greg worked on replacement trans seals and DSSR shifter install. Brad has also been a pleasure to work with over the phone and in person for parts and quotes. Wonderful shop and amazing people!
