Built on BMW's UKL2 chassis architecture with xDrive all-wheel drive, a front Torsen mechanical LSD, and advanced ARB wheel slip limitation, the M135i xDrive is an incredibly agile cornering machine. However, the factory suspension can still be heavily optimized for flatter cornering and sharper turn-in on track. Achieve complete ride height and damping adjustability with fully adjustable Coilover Kits. Eradicate chassis flex and lock down your alignment under hard cornering loads using stiffened polyurethane Suspension Bushes, rigid Suspension Braces, uprated Control Arms, and adjustable Drop Links, supported by our full selection of Misc Suspension Parts.
