European Auto Source

European Auto Source is a performance shop and parts retailer focused on BMW, with a growing line of Toyota GR Supra and Tesla upgrades. The shop sells suspension, exhaust, wheels, seats and tuning parts, and it installs much of what it sells. Its in-house services include DME unlocking for BMW S58 and B58 engines, coding and programming, rod bearing service on S65 and S85 engines, manual conversions and dyno tuning.

Customers say the staff answer questions well and that work is done as quoted, with some installs finished the same day. The shop is at 4015 East Leaverton Court in Anaheim, and it also takes phone calls at 714.369.8524 and online orders through its site.
