Stock height? I am as low as I can go with 18x7.5's 50mm offset w/ 215/35/18's. Stock height you would be fine with 48mm. I'm pretty sure 48mm offset will work if you roll the fenders if you are lowered.
question is: Do I have to make any modifications if I purchase 18 inch rims and tires
Yeah it is completely stock!!!! So it seems 18 would be okay, but the wheel base looks a little tight, do you have any problems with your turning at all
Also what is a good place to get rims at a decent price
Yeah,go w/ 17s.18s are overkill for the Protege.I was gonna stick w/ 16s but since I'm gonna do a lot more w/ my car(suspension,appearance and a little more power)it would be better that I upsize.
I've got the same ENKEI's as the blue sedan pictured above.
Mine are 225/40/18 with stock springs, the tires ride very hard (feels like I dropped the car the ride is much much stiffer). The offset I think is +45 or +42?? When there are passengers in the back and I hit a speedbump it rubs slightly on the drivers side.... I think if I was running 215/35/18's there would be no rubbing.
