Can I get the shocks and struts by themselves and not do the lowering springs? I read that it was good to get the springs because they work well with this kit. However, I have a staggered set of 20's and I do not desire to lower the car at this time. (To avoid any rubbing) Or should I just get the coil over kit and adjust whenever I remove the 20's and install my 17's for the track?
While the springs do work well with this kit, they are not required. These will work just fine and improve handling quite a bit with factory springs. If you want ride height adjust-ability, Coilovers would be a good option.
