The Sport+ Spring set by Top Line Parts is designed to replace your stock Super Beetle springs exactly, but with some performance enhancements. First, there should be a slight lowering effect on the front end ride height. The exact amount of lowering will sometimes vary due to the condition of your old springs. You should normally see approximately 3/4" to one inch of lowering. (Up to 1 1/2" on convertibles.) Our tapered design gives extra clearance for oversize tires, while still fitting the stock spring holders. We have removed the non-functional progression of the stock spring, and increased the spring rate about 10% over the stock spring. This spring is very streetable, and can be used successfully with our Versa-Strut lowering kit. since you are lowering a bit, you will lose some caster setting. To restore caster to stock, we suggest our Caster-Fix bushings be installed along with this item.. Upgrade your suspension today!
