I am unclear what backspacing I have to run or what pad height. I like the S71 and S77 setups, and would want to run a 305/45/18" setup out back. Itll help my gearing being that I am 3.73 and having a taller tire.

But what kind of backspacing and overall rim size should I be leaning towards? Does an 18" even clear in the front?

A 305/35/18 is only 26.4" tall. How big of a tire are you running now?

You will want the following

18x5 2.10 backspacing -23 offset
18x10 7.70 backspacing 56 offset

let me know if I can help out in anyway.

Thanks! What about pad choice? They offer low medium and high.

Will a 305/45 width work on that back spacing without rubbing?

With Brembos in front it is only accept 5" for 17" and 18". Otherwise you go with 20" to get 20x7 or 20x8.

This is confirmed by WELD.
You are correct sir.
