Thanks. Yeah no way in the world would 4.5 backspace work for me. We even tried a 3/8 spacer and the tire still hit the drivers side spring.
It is a 4.5 bolt pattern. The springs are XHD from Mancini I bought a couple years ago. The car definitely sits pretty high in the back.
Yeah.. maybe someone did shorten the axles before we got it.. I guess anythign is possible.
Right now I have 3" backspace on I believe a 7 inch rim with 255 that works well but 3.5 will definitely work with 275.
