ST Suspension Height Adjustable Spring Kit - BMW F80 M3 Incl M3 CS

ST is KW's sister brand, and its height adjustable spring kit is one of the most cost-effective ways to lower an F80 M3 properly. The springs sit on threaded perches around your existing dampers, so you set the stance you want and the car keeps its standard damping, including Adaptive M if your car has it.

Lowering range on the F80 M3

• Front: 5–25mm lower, adjustable
• Rear: 5–25mm lower, adjustable

Fits the F80 M3 saloon, including the M3 CS.

What's included

• Springs matched to the factory dampers
• Threaded height-adjustable spring perches
• Vehicle-specific bump stops and dust protection

How it compares

The KW height adjustable spring kit does the same job and is the step-up option. If you'd also like to adjust the damping, look at the KW V3 or the AST 5100 Street for the F80 M3. Have an M4? See the ST kit for the F82.

Fitting at String Theory Garage

We fit, set the ride height evenly and realign the car in our workshop. Get in touch when you order and we'll book you in. If you go to the bottom of the range, add AST adjustable drop links to keep the anti-roll bar geometry right.

Questions we get asked

Does the ride get firmer?
The dampers are unchanged, so the car keeps its standard damping; it just sits lower. We can talk you through what to expect before you order.
