I have an 06 GTO an I am looking to put some ET streets out back but am not very sure about the backspacing I should be looking for on the wheels...can anyone be of assistance here?? 15 x ? also looking to see if anyone has done the pro ractchet style shifter with the nitrous button on the top in a car like mine and is it a drect fit application. Thanks

NOTE: Your GTO uses the Holden (and BMW) bolt pattern 120 mm not the standard / US GM bolt pattern of 4.75 inches (which is equal to 120.65 mm) - so be aware of that difference. Some people say there are zero issues, but back in 05 HPP ran an article on how to modify standard US GM rims to properly "fit" on a Holden Goat.

there are a bunch of people on the gto forum that run fbody welds on gtos
You can fit a 15x10 if you roll the fenders and have drag bags or drag springs. 15x8 with 7.5 bs should fit without much problem depending on what size tire you choose.

You just use hub rings if you don't get the correct bolt pattern. Weld makes wheels in the correct pattern and you can run a 15x10 with 7.5 B.S.
