Is this set up ok for a 1 inch Eibach prokit w/ fender roll and Camber Kit to the rear? Try to change rear from 255/40/18x8.5 +47 to the following set up:

BF Goodrich g-force t/a kdw

225/35/18x7.5 Front +50
235/40/18x8.5 Rear +47

 

if you have rolled rear fenders and a camber kit you can fit a 245/30 in the rear. with the front i would go with a 215/35
