KW Lowering Springs - Porsche 911 964 - 25371043
KW Automotive lowering spring sets are the simpler alternative to a full coilover kit: they bring the ride height down and firm the car up slightly, using the dampers already fitted, provided those are listed as compatible. A good answer for a lower stance and firmer handling without paying for an adjustable system.
KW lowering springs bring the ride height down by a fixed amount, with no adjustment, keeping the car's standard dampers where the maker has confirmed they suit the new springs. The right answer for a visible drop and firmer handling without the cost and complication of a full coilover kit.

Frequently asked questions
Can KW springs be fitted to the original dampers?
Only where they are listed as compatible for your car. Check the product page: some models need specific dampers, confirmed by the maker.
How far does the car drop?
A fixed amount, specific to each model, shown on the product page for front and rear in millimetres. There is no later adjustment.
Does the geometry need setting after fitting?
Yes. Lowering changes the steering angles, so have it checked at a specialist workshop.
Are extra parts needed to fit them?
Sometimes, for example shortened bump stops. Check the technical notes for your car.
How does it differ from a full coilover kit?
Lowering springs come without new dampers and without height adjustment: a simpler and cheaper answer.
Do they work with factory air suspension?
No. They generally do not work with air self-levelling or electronic damping. Check the technical notes.
What warranty do KW products carry?
Check the warranty terms shown on the product: they vary by application.
Can they be fitted front only, or rear only?
It depends on the car. The product page says whether the set covers both axles or one.
