McLaren 720S Progressive Rate Lowering Springs McLaren 720S Progressive Rate Lowering Springs Description McLaren 720S Progressive Rate Lowering Springs Set of 4 VelocityAP lowering springs for Mclaren 720s Models to reduce the ride height on your car by 7/8", or 22mm.  VelocityAP springs use exclusively high quality, high stress X5K Spring Steel. Although considerably more expensive than regular steel, this new generation steel allows us to further improve upon the original Jaguar F-Type spring design by reducing the amount of steel required in a spring. VelocityAP springs are therefore substantially lighter (by approximately 30%) and reduce the solid height therefore increasing travel. X5K Spring Steel is used in almost all top levels of Motorsport, giving a hugely successful endorsement of its characteristics & proven durability. In addition to the superior materials, these springs also feature a unique manufacturing process that sets them aside from most OEM & Aftermarket applications - a Tapered Wire Progressive Rate design. The Ultimate in Design. The principle is simple: By using a tapered rather than constant diameter spring wire, our springs achieve a truly progressive spring rate over the length of their compression & travel. The spring rate increases when you need it (cornering) and decreases when you don't - yielding a smooth and supple ride over bumpy surfaces. The best of both worlds! By using this unique manufacturing method, we can achieve a substantial increase in spring rate with huge handling benefits with no loss of ride comfort. As the spring de-rates, the shock absorber no longer struggles for rebound control and gives improved vehicle stability. Benefits: Reduced Weight Improved Ride Quality Improved Handling Better Visual Appearance Improved Shock Absorber Function FITS MCLAREN 720s MODELS Click image to enlarge Images sell!
