The K&W's use an open spring that fits into the control arms like the stock springs. The adjustment perch is at the top in the spring pocket. The only way to adjust ride height is jacking up the car to take weight off the wheels and unloading the springs. It makes corner balancing labor intensive. The kit is single adjustable (compression) and comes with Koni shocks valved to K&W's specs. I blew out the fronts bottoming them out. I had the car too low, split the bump stops and bottomed out the shocks. The replacements were $411.20 each in 2013. They ride nice on a good road. Bad road = rough ride. My car has retired from racing and I'm most likely going back to my K&W's, otherwise I'd offer them to you. You may be able to find a used set. A few owners bought them and hated them for various reasons.
