Is there a huge overall difference betwwen sprot and race springs if they are both said to give the same drop? Is the firmness that much worse with race? Also is it a bad idea to get race springs in an area that has pretty bad roads? Also can I go with nuespeed sport springs wihtout a camber kit? How about with H&Rrace springs without a camber kit? Also is it a huge differnece of wear on my stock shocks betwwen 1.5 inch drop and 1.7? thanks
