AST Suspension 5100 Street 1-way Adjustable Coilovers - BMW M4 G82 xDrive

The xDrive G82 M4 is the one most owners drive all year round, so its suspension has to cope with cold, wet, broken roads as well as the occasional fast lap. The AST 5100 Street replaces the adaptive dampers with a monotube coilover and a single 12-position adjuster, giving you a lower stance and better body control without making the car a chore.

What's in the box

• AST 5100 Street dampers and springs specific to the G82 xDrive, at AST's recommended rates
• 12-position damping adjustment from soft to firm
• Monotube, gas-pressurised construction for consistent damping as the dampers warm up
• Height-adjustable ride height
• Uses your factory top mounts, with an optional With Top Mounts upgrade that adds front camber adjustment

xDrive has its own kit

AST makes a separate kit for xDrive cars, so check which you have before ordering; the RWD version is here. The same xDrive kit fits the G80 M3 xDrive.

Alternatives

If you'd rather keep the adaptive dampers, the KW height adjustable spring kit lowers the car on the factory units. For more track-focused hardware, see the AST 5100 Comp for the G82 xDrive.

Questions we get asked

Is it suitable for daily driving?
Yes. With the adjuster towards the soft end it's designed for exactly that. Firm it up a few clicks for a track day.

Does it affect the four-wheel drive?
No. It replaces dampers and springs only; the driveline isn't touched.
