ST Suspensions TA Height Adjustable Coilovers – BMW M3 (E46)

OVERVIEW

The ST XTA coilover kit for the E46 M3 pairs height adjustment with rebound damping adjustment and adjustable top mounts, so the car can be set up for the road one weekend and the track the next.

ST is the value brand of KW Automotive. The XTA sits at the top of the ST coilover range: height adjustable, with 16 distinct clicks of rebound damping adjustment and aluminum unibal top mounts that also allow camber adjustment. The struts are galvanized zinc-coated steel and the spring perch is a composite polyamide item with a stainless steel insert. The kit ships factory-preset and includes a damper setup manual.
