i have a 2003 tiburon gt. i want to get lowering springs for it and i want to get it as low as possible without any rubbing or any other complications. i have seen kits ranging anywhere from 1 to 2 inch drops. i am also going to get a set of rims. i have done some research and i think that 18x8's with a 40 mm offset will work with 215/40/18 tires. can somebody tell me how low i can go and not have to worry about rubbing with those rims and tires?
