Started in 1998, UUC Motorwerks is a household name for BMW drivetrain and chassis performance. UUC has made a name for themselves with their ultimate short shifters, double shear selector rods or DSSR, as well as having worked with exhaust manufacturer Corsa to develop winning exhaust systems for many BMW models. Clutch and flywheel upgrades are also one of UUC's key focal points - they offer lightweight flywheels that retrofit larger M5 and V12 clutch kits to improve power holding capabilities.
