Looking at getting a set of Weld ProStars 15x3.5 for the front of my '89 GTA. What would be the correct back spacing for this combo.

1.75" backspacing...that's what my Draglites are and fit fine.
In fact I think with the 15 x 3.5 Prostars or Draglites, that's the only backspacing available for that size.
