Re: Standard Rally Wheel Backspacing?
The issue with aftermarket rallys, like the Wheel Vintques, is they are lug centric. The OE Kelsey Hays rallys, which are still available new from Year One (don't know if the other big resellers have them) are not much more, and they are the correct hub centric wheels. I believe that they only sell them in black.
I had a set of WV lug centric rallys on my 68, and always had a wheel vibration. You can buy rings to fill in the gap and make a lug centric wheel almost hub centric, but it is just not the same as having a solid, straight set of OE rallys.
All of the 15x8 GM supplied rallys I have ever seen were the aforementioned 4 inch BS.
