Hi I just received my 15x7 astros and wanted to mount them, the thing is that they fit perfect in the front, but in the back the center bore diameter of the rims are a little bit too small, so they dont fit excactly. I tried it then with a 1/4" spacer so i dont have the problem with the center bore, but now the studs are too short to mount the wheels with the nuts. some guys here had the same problem how do you solved it?
Before you kill yourself, those wheels dont use conical seat lugs. They take a mag shank lug nut! Bring your wheel to a local custom wheel place and have them sell you the right lugs
A lot of rims locate off the axle not the lugs if the wheel opening is too small you either have to machine the wheel centers or the axles. I would not advise using a spacer at all but when you do the wheel still has to fit over the axle. Like was stated get this corrected before you try to drive the car.
