BMW M340i Coilover Suspension Kit - Dinan - DIN CSS (2019–2026). Dinan’s spring-based solution that sharpens handling while keeping day-to-day comfort.

DIN CSS uses calibrated spring rates to cut body roll, brake dive, and squat. For best results, pair with the recommended Ride Quality & Handling Kit to maintain travel and reach the stated drop. Springs are CNC‑wound from high‑tensile chrome‑silicon, shot‑peened, and preset to resist sag. Compatible with conventional or factory electronic shocks. M340i RWD lowers about 1 in front/rear with ~15% stiffness increase; M340i xDrive lowers about 1 in with negligible front change and ~10% rear increase.
