I know this question has been done to death in many forums. I research many of them before purchasing Wheel vintique 55 series Ford style steel wheels. 15x7 4.25 backspace. Goodrich radial TA 215/60 15..
All of the forums said no problem. However I had clearance issues to the upper strut when I installed them. Without a space the would have been interference. I have installed a 3 mm spacer and that has provided minimal clearance but left the stud length on the low side. Car is all drum brake car. Is the any experienced the same issue? Can I get long wheel studs? Where?
Any experienced comment will be greatly received.
