Max Backspacing on Cobra IRS????

[killspray]

Help.

Been searching on Google and on SVTP and I'm stuck. So far, it looks like 6.75" backspacing works on a Cobra IRS with no interference with IRS bolt... what about 7" bs?

Thanks a bunch,
Steve

ok, so the MM low profile irs bolts will allow you to run 10.5 wheels but is that a 10.5" wheel with 7" backspacing?

Ok, so here is what I found:

option 1: Buy low profile IRS bolt with the risk of it stripping for only $14
option 2: Shave the stock IRS bolt if you are brave enough for free
option 3: Purchase 3/8 spacer for $50-$100

sound about right?

I shaved mine and run a 315 tire on a 10.5 rim. Took about 10 minutes to do
