Adjusting them is a pain. You have to compress the spring or take the suspension apart. The perch sits on top in the spring tower and you can hardly see it let along adjust it. But once you get it where you like it, you won't be touching it again. Mine have been installed for about a year now. Most people would find them too stiff for day to day and I find them a little tame for racing. However, they made my car a lot faster and easier to drive faster.
