[QUOTE="bat-stang, post: 9561094, member: 39895"] That sounds correct to me. Wheel rate has to do with actual force exerted by the spring measured at the contact patch. On the front of our cars, with the spring in the stock location, the wheel rate is 25% of the spring rate; with a coilover setup, that wheel rate is 90% of the spring rate because the spring acts on the wheel spindle as opposed to the spring perch. This allows for a more comfortable ride due to a softer spring, but a higher wheel rate because of location. IE: wheel rate of a 350# coilover spring is like 300#; to get a 300# wheel rate out of a spring in the factory location, it would have to be a 1200# spring--with a very rough ride. I forget all of the mumbo-jumbo on the irs; new to it actually. However if I were to guess, I would say that with coilovers in the rear, the wheel rate will probably be close to that of a stock located spring due to the fact that the stock spring and the coilover shock mount are very similarly located on the lower control arm. :coolman: [/QUOTE]
