This M3 CS is built like a race car that passed for a street car. M-Tech’s single-turbo 7275 setup paired with the Bully stroker kit and stage 2 Deka transfer case turn the S58 into a serious powerplant. Charge-air manifold, FMIC, port injection and downpipes keep boost and fueling in check, while KW springs and lightweight billet hardware tame the mass. REV2 controller and FEMTO ECU unlocks polish the tune. It wears custom CC wheels and a small rear brake kit — focused, brutal and ready to launch.
