ST Suspensions XTA Plus 3 Non-EDC Coilover Kit - BMW M3 (E9X) 2008-2013

The ST XTA plus 3 is a three-way adjustable coilover kit built by KW for ST, with independently adjustable high-speed compression, low-speed compression, and rebound damping so the car can be dialed in for street, track, or a chassis whose corner weights have changed. It runs a twin-tube damping principle in a galvanized strut housing that is sealed multiple times and given an additional corrosion-resistant coating, with a mono-block guide and seal package that cuts damper friction. Linear race springs sit on a polyamide composite spring perch with an embedded stainless steel insert, and solid aluminum uniball top mounts sharpen steering response while allowing camber adjustment where the application supports it. Ride height adjusts on the threaded strut housing, 0.4 in to 1.6 in at the front and 0.2 in to 1.4 in at the rear.
