I purchased the Megan Racing coilovers for the FiST and want to set the height before I install them. I only want to drop between 0 to 20mm all around, but I do not know what length to set them at. the spring rates are linear and 200 at the front and 170 at the rear. I plan to put an inch of preload on the springs at both ends. I really just want to have a stiffer spring rate because I'm using 17x9s with a 235-40 tire and it will only rub the fenders when I hit a big bump on a highway, and when I am saving time on the interchanges the body will roll enough to contact before the tires slip. There will likely have to be adjustments after they have been put on the car, but I'm trying to get them as close as possible while they are easy to access
