ST Suspension Height Adjustable Springs Kit - Lowers 10-25mm

An ST Suspension Height Adjustable Spring Kit is the ideal solution if you want to keep your car's stock dampers but still enjoy the benefits of adjustable lowering like you would get with Coilovers.Individual height adjustment of the standard suspension kitAdaptive damper control remains activeVehicle specific spring ratesImproved steering behaviourWhereas a normal spring kit generally offers a fixed amount of lowering, ST Suspension's Coilover spring kit comes with its own adjustable spring seats/perches which replace the fixed factory items allowing the lowering level of each to be fine-tuned individually, even after installation.Taking only a little more time to install than a lowering spring kit (perhaps an extra hour to fine-tune the lowering amount) this kit replaces the stock, non-adjustable spring seats/perches and generally includes springs precisely matched to the factory dampers, adjustable perches/seats, with the addition of application-specific bump-stops and dust-covers included.Unlike conventional Coilovers which replace the adaptive dampers or an expensive electronically adaptable Coilover set-up this upgrade goes straight onto the factory adaptive dampers.Many of the springs provided are progressive rate. Progressive rate springs are ideal for fast road use. The spring is softer in the middle so for small compressions (e.g. small bumps and imperfections in the road) they remain compliant but firm up as it compresses further to provide excellent body control and taut, predictable handling through corners. ST specifically select the best spring for each application on a kit-by-kit basis.Each kit is carefully tuned to match the factory dampers on the car it is intended for. These are proving to be a popular upgrade on high-end performance models with adaptive damping from the factory.All ST Suspension springs are manufactured to the highest standards. Each part number is individually TUV certified for peace of mind and to meet local legal requirements. Springs are manufactured from chrome-silicon Steel with a tough weather resistant coating.Lowering amounts may vary for a special edition or sports models where lowering has already been applied at the factory.
