Right-Hand Front Damper - Bilstein B4 22-304445 for BMW Z4 G29 and Toyota GR Supra A90 A91

Bring back the sharp, planted feel your car left the factory with. The Bilstein B4 22-304445 is an OEM-spec, gas-charged twin-tube strut for the right-hand front position that restores control, comfort and confidence on UK roads. Perfect when your BMW Z4 G29 or Toyota GR Supra starts to feel bouncy, vague or crashy over bumps, this high-quality shock unit returns your chassis to tight, precise responses without adding harshness.

Why enthusiasts choose this RHF damper

• Direct-fit offside front strut for a straightforward swap and correct geometry
• Factory-level build quality and durability backed by Bilstein’s engineering
• Consistent, fade-resistant damping thanks to gas pressure twin-tube architecture
• Improves turn-in, traction and stability while maintaining everyday comfort
• Ideal for daily driving, spirited B-road runs and a proper suspension refresh

We have installed many of these B4 units on customer Z4 and GR Supra builds and the feedback is consistently positive. Expect a tighter front end, better composure over broken tarmac and a reassuring, OEM feel on long trips.
