Bilstein B3 36-160235 - BMW 3 Series E90 E91 E93 Rear Suspension Spring

Bring your E9x back to how it should drive with this Bilstein B3 rear suspension spring, part number 36-160235. This original-spec back spring restores factory ride height, comfort and stability on BMW 3 Series Saloon, Touring and Convertible models, including RWD and xDrive variants. If your back end sits low, a coil has snapped, or the car feels unsettled over bumps, this is the direct-fit solution that puts everything right.

We run these B3 units on our own cars and feedback from MJ Modifications customers has been outstanding. Expect a quiet, refined ride, consistent stance and the reassuring control you want from quality German engineering.

Why this Bilstein B3 is a smart choice

• Direct swap for the original rear spring with correct rate and standard ride height
• High-tensile spring steel built for durability and break resistance
• Hot-set and stress-relieved to minimise sagging and preserve height over time
• Shot-peened and coated for strong corrosion protection and long service life
• Precise geometry for OE fitment including pigtail and minibloc style ends
• Consistent performance that complements stock dampers and everyday road use
