Designed for real-world roads

Unlike fixed drop sport springs, this height-adjustable setup lets you fine tune the stance of your V8 M3 to suit different wheel widths, tyre profiles and usage. Lower the centre of gravity for better agility and a level, aggressive look, then set the height exactly where you want it. It is an ideal coilover alternative for drivers who want adjustability while keeping the smooth, stock-damper ride.
