Built for road and track

From B-road blasts to circuit sessions, this E46 suspension package delivers confident body control and a planted feel. Wind on more rebound for greater high speed stability and reduced roll, or soften things back for daily comfort. The aluminium top mounts allow you to add negative camber for tyre bite and improved steering response, with caster adjustment available where the application allows.
