Quote: Sorry, I think you are fighting a loosing battle, If you want 15x8 Rallye wheels to have a trim ring that fits I suggest you have them made with 1 inch more backspace than the 15x7 Rallye's then the 15x7 trim ring will look right on a 15x8 rim. I don't think it will work with the offset you are looking for on the front
You are 100% right. The only reason the wheels posted above on that Dart or Valiant fit the trim rings right has to lie in the offset.
I never took a tape measure to this but here is my old Cuda with 15x8 and 15x7 stock rings. Ron
