BMW M235i Coilover Suspension Kit - Dinan - DIN CSS - '15-'21. A Dinan-engineered spring-based suspension package for the F22 M235i/M240i xDrive that tightens body control without sacrificing ride quality.

Built around Dinan DIN CSS performance springs, this system pairs calibrated rates with supplemental bump stops/perches to preserve travel, reduce roll, and improve mechanical grip. Ride height is lowered approximately 0.5 in front and 0.625 in rear for improved geometry and a composed stance. Springs are CNC wound from high-tensile chrome-silicon wire, shot-peened, and preset to resist sag for long-term consistency. Compatible with conventional and factory electronic shocks; not for RWD or convertible models. For best results, install with the matching Ride Quality & Handling Kit; omitting it may negatively affect ride and handling.
