JH Motorsports

JH Motorsports is a performance and maintenance shop focused on Audi, Volkswagen and Porsche vehicles, and it also sells aftermarket and replacement parts. The shop offers scheduled maintenance and factory-level repair as a dealer alternative, along with APR and JHM tuning, turbo and supercharger kit installation, and brake kit work. Its catalog covers tuning software, exhaust, shifters, transmission parts and performance brakes.

Work is done in its on-site facility, and the shop says it can flash most APR-tuned vehicles while you wait. Parts are also available for local pickup, and most in-stock orders ship the same day when placed by 2:00 pm Pacific Time. The shop is located on South Harlan Road in Lathrop, California, and phone and email contacts are listed on the site.
