car is a turbo 6liter. currently swapped over to a 29" hoosier QTP. problem is the fender is hitting the tire on the passenger side under power. im not 100% sure but i beleive there is moog stock replacement springs in there that i installed maybe 5 years ago? is there a stiffer spring most run? is there one brand over another when it comes to ride height? not looking to go to coil overs so that is out of question. thanks guys
