KW Height Adjustable Spring Kit - BMW G80 M3 / G82 M4

If you like how your G80 M3 or G82 M4 drives and just want it to sit right, this is the kit. KW's height adjustable spring kit fits new springs on threaded perches around your factory dampers. You choose the ride height within KW's tested range, and the adaptive dampers and M Drive settings carry on working exactly as before.

What you get

• Vehicle-specific springs, matched to the standard dampers and the car's weight
• Threaded, height-adjustable spring perches, so you can fine-tune the stance to your wheels and tyres
• Vehicle-specific bump stops and dust protection to look after the factory dampers
• Your adaptive dampers, driving modes and driver-assistance systems all stay active

Why choose this over fixed lowering springs?

Fixed springs give you one height, and it's often not quite the one you wanted. With this kit you can set the drop to suit your wheels, raise it slightly if the car needs to clear a ramp or a speed bump, and correct small side-to-side differences. The lowering range differs between RWD and xDrive cars, so tell us which you have and we'll confirm the exact figures.

How it compares

If you want adjustable damping as well as height, step up to the KW V3 coilovers or the AST 5100 Street for the M3 or M4. If you have the M3 Touring, see the KW kit for the G81.

Fitting and setup at String Theory Garage

We fit KW kits in our own workshop and finish every job with ride-height setting, corner weighting and a full four-wheel alignment. A spring kit changes your ride height, so the alignment needs resetting afterwards; we do that as part of the job. Get in touch when you order and we'll book your car in.

Questions we get asked

Will it make the ride harsher?
The springs are matched to the factory dampers, so the ride stays close to standard. You keep all the damper modes, so Comfort still feels like Comfort.

Can I fit it myself?
It's a strut-and-spring job that needs spring compressors and an alignment afterwards. We'd recommend having it fitted, but get in touch if you have questions.
