Product Description

The Bilstein 46-242792 is a B12 Pro-Kit complete suspension lowering kit engineered for RWD variants of the BMW E46 3 Series, covering the 323i, 323Ci, 328i, 328Ci (1999-2000) and the 325i, 325Ci, 330i, 330Ci (2001-2006) across sedan, coupe, convertible, and wagon body styles. The kit pairs Bilstein's B8 Performance Plus upside-down monotube dampers with Eibach Pro-Kit progressive lowering springs, both road-tested and tuned together specifically for the E46's suspension geometry and 50/50 weight balance. The result is 25mm of front drop and 10mm of rear drop that visibly transforms the car's stance while delivering tighter body control, reduced roll, and a more direct, connected driving feel without sacrificing day-to-day comfort.

Installation is direct bolt-on with no modification required, and OE suspension geometry is preserved at the lowered height - eliminating clearance concerns with tires, fenders, or bump stops. The kit is compatible with all six-cylinder RWD E46 variants across all body styles but excludes the AWD 325xi and 330xi, the M3, and vehicles equipped with factory self-leveling rear suspension. Backed by Bilstein's Limited Lifetime Warranty and made in Germany.
