Give your classic BMW 6 Series E24 the poised, planted feel it deserves. This Bilstein B6 rear unit is a direct-fit, heavy duty upgrade that tightens body control, sharpens response and boosts rear-end stability while keeping factory ride height. Ideal for fast road use and daily driving, it delivers confident damping without the harshness of track-only hardware.

We have fitted this damper to customer E24s and the feedback is outstanding. Expect crisper turn-in, better traction out of bends and a calmer, more composed rear axle over poor surfaces. If your original shock has gone soft or you want a meaningful handling improvement with standard springs, this is the go-to solution.

• Improved grip, reduced float and stronger high-speed stability
