AST Suspension 5100 Street 1-way Adjustable Coilovers - BMW M4 F82 (5-Bolt)

The AST 5100 Street is a road-focused coilover for the F82 M4 that settles the car over bumps, cuts body roll and lets you set the ride height. This listing is for 5-bolt cars, which covers most M4s built from early 2015 onwards.

3-bolt or 5-bolt?

Open the bonnet and count the bolts on top of each front strut. Cars built up to around December 2014 have 3; later cars have 5. If yours has 3, use the 3-bolt listing. The bolt pattern matters if you choose the top-mount option. If you keep your factory top mounts, tell us your build date and we'll confirm the right parts.

What you get

• AST 5100 Street dampers and springs for the F82 M4, at AST's recommended spring rates
• 12-position, single-adjuster damping that's easy to change and easy to feel
• Inverted monotube front struts, gas pressurised
• Adjustable ride height
• Factory top mounts as standard, or the With Top Mounts option with front camber adjustment

How it compares

The KW V3 offers separate rebound and compression adjustment. If you only want to lower the car, see the KW or ST height adjustable spring kits. For a track-focused M4, the AST 5100 Comp (5-bolt) adds camber-adjustable top mounts front and rear.

Questions we get asked

Does it work with Adaptive M Suspension?
The AST dampers replace the adaptive units, so the damper modes no longer apply. Ask us about switching the system off cleanly when you book your fitting.
