Allright, I recently just got a set of rear draglites for my camaro. At first I was just going to run them at the track, but now that I've driven on the street with them, and realized that even though I have MT drag radials on them, they handle better than my 235 GY GT-HR II's in the rain. So now I am thinking of running them on the street, but I want to get a set of street legal fronts. What offset would I need to run a 15x7?
