ST Sport Springs - Audi RS5 B9 - 273100BS
ST Suspensions 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.
ST lowering spring sets are a direct replacement for the standard springs, with a fixed drop within the limits approved for each car. An affordable answer for a visible change and firmer handling, without height adjustment.

Frequently asked questions
Can ST springs be fitted to the standard dampers?
It depends on the car: some models need short-stroke or sport dampers. Check the technical note for your model.
How far does the car drop on this spring set?
The drop is fixed and varies by model. The product page shows the approved figures for front and rear.
Can the drop be adjusted after fitting?
No. Lowering springs are a fixed height; adjustment needs a coilover kit.
Is a geometry check needed after fitting?
Yes. Have the geometry checked and set at a specialist workshop after fitting.
Do they work with factory air suspension?
No. These sets generally do not work with factory air or self-levelling suspension.
How long does fitting take?
The existing dampers have to come off to change the springs. Have it done at a specialist workshop.
Do the springs affect ride comfort?
A drop within the recommended range is fine for normal use, though bumps come through slightly more firmly than on standard suspension.
What warranty do ST springs carry?
Check the warranty terms shown on the product: they vary by application.
Can ST springs be combined with another brand of damper?
That depends on the damper's specification. Ask for technical advice before mixing parts from different brands.
Are they suitable for daily use?
Yes. They are built for daily road use, with a moderate drop compared with competition parts.
What is the difference from a full coilover kit?
A spring set changes only the spring, keeping the dampers already on the car where those are compatible; a coilover replaces both and adds height adjustment.
Do they need individual vehicle approval?
That depends on local law and on the car. Check the technical note on the product.
Can I fit a front-only or rear-only set?
The sets are sold complete, front and rear, so the car stays balanced.
Does it change the wheel angles after fitting?
Lowering changes the steering angles slightly. A geometry check is recommended.
Are they suitable for a heavily loaded car, or for towing?
Check the approved maximum axle load for your car before running it loaded often.
