I recently upgraded the rear suspension on my old school class 5 to coilovers. I bought these new shocks off a guy who said they came off the front of a toyota truck. So I put the shocks on the car and I liked the ride height so I stayed with the coils which have a 12" 600lb under a 350lb 10" with 2" of preload. I also have a 2 tube bypass on it which I made no changes to. I went to the desert and the rear was real stiff over whoops but felt good over big jumps. My question is should I mess with the valving in the coilovers or are the coils to stiff, but will I change the coils will I be able to bet the same ride height? Thanks for any help.
