does anyone have any experiance on how does these proform vs the Sport-tuned suspension from the 2004?? and does these ride smooth? or pretty bumpy?? or what?? (details??) im from nor cal.. i'm interested in getting these but.. the raod is pretty bumpy around here..

 

Do you have a coupe or sedan? 04 coupes didn't have a sport tuned suspension. Z-Htechs are slightly stiffer in the 04 stock setup, but probably won't be very noticeable
