Putting 300+ horsepower through the rear wheels of your M135i via either the 6-speed manual or 8-speed ZF8 automatic transmission demands robust drivetrain hardware. Manual owners upgrading power output will benefit immensely from Uprated Clutches & Flywheels (including the popular 550i upgrade) designed to handle elevated torque without slipping. From the factory, the M135i lacks an open-diff alternative; installing high-performance mechanical Differentials (Limited-Slip) completely transforms rear traction, corner-exit speed, and power delivery. Eliminate rear subframe axle movement and flex under acceleration with polyurethane Drivetrain Bushes, supported by our complete range of Misc Drivetrain Parts.
