AST Lowering Springs – BMW F80 M3, F82 M4 & F83 M4

Product Description

AST lowering springs provide a fixed reduction in ride height for the BMW F80 M3, F82 M4 and F83 M4 Convertible while retaining the compatible original dampers. Each option is a complete, model-specific front and rear spring set; select the body style and lowering specification together.

The springs use cold-coiled construction and a progressive design. They do not add threaded height adjustment or replace the damping system. The fitted height depends on the original vehicle specification and condition, so alignment and wheel and tyre clearance should be checked after installation.

FAQs

Can the ride height be adjusted after installation?

These are fixed lowering springs, not a threaded height-adjustable spring kit. The selected part number determines the front and rear spring specification.

Do I need an EDC cancellation kit?

Not simply for fitting these springs. The correctly matched original dampers remain in service, including their electronic control where fitted.

Should the alignment be checked?

Yes. Check alignment and wheel and tyre clearance at the new ride height using the actual wheel specification fitted to the car.
