Product Overview
Bilstein B12 Pro-Kit – BMW E46 M3 Coupé & Convertible (2001–2006)
The Bilstein B12 Pro-Kit is a complete, matched suspension package for the E46 M3. It combines Bilstein monotube performance dampers with Eibach Pro-Kit progressive lowering springs, road-tested and tuned to work together. That’s a big improvement on mixing springs and dampers from different brands, which often leaves a car crashing over bumps or skipping mid-corner.
What it does
- Lowers the car by approximately 20 mm at the front and 10 mm at the rear, enough for a cleaner stance and lower centre of gravity without compromising usability.
- Sharpens response with less body roll, better turn-in and more composure at high speed.
- Keeps the ride civilised, because the progressive springs stay comfortable on the road and firm up as the load increases.
Please note
The B12 Pro-Kit is a fixed-height, non-adjustable damper and spring kit, not a height-adjustable coilover. It’s ideal if you want an OE-quality, fit-and-forget upgrade. If you need adjustable ride height or damping, ask us about coilover options for the E46 M3.
The dampers are finished in Bilstein yellow and the springs in Eibach dark grey. Fitting requires the original strut spacer to be retained, so please follow the instructions supplied. Have the car aligned after fitting.
