tires front 275/35/18 rear 295/35/18. Currently stock height but 130,000 miles on body may mean a bit o sag. No tire clearance issue at this point but if i do springs and use eibach sportline will i have any rub issues? The difference in tire sizes gives her a half inch raise in the back over the front, i wish to correct this and want to lower the back 1/2 inch more than the front so was thinkin of usin sportline in back and proline up front, wich from advertised ratings should make about 1/2 inch lower rear correcting for the fatter meats in the back. Anyone out there with similar size tires and a lowered car any input would be greatly appreciated. plus the sell the sportline rears separate but i cant find the proline fronts separate??? O the rims r roh with supposedly the correct backspacing for genIII f, 9" front 10" rear
