These are essential for a race car but also very useful for dual purpose cars as well. You can set the ride height wherever you want, and change it in only a few minutes. The threaded sleeves sit on a machined collar (provided) that must be welded to the strut. The lower perch is threaded on it's ID so you can turn it up or down to change ride hieght. The kit is designed for use with 2.5" ID springs. The springs come in 25 lb. increments and various lengths. I suggest a length of either 7" or 8". Picture shows typical installation on a 2002.
Race cars are normally lowered so much that the front shock travel becomes insufficient. For race cars the front strut housings are shortened 2" to restore shock travel. In this case special shorter bodied Bilstein's are used which are available elsewhere on our catalog. We will provide a drawing showing where to cut and weld, or we can do it for you.
