Ridetech Tru Turn/68 Camaro

[rgen19]

I realize this topic has been beaten to death but when laying out lots of money for forged wheels I want to be sure. My set up: stock subframe, stock height subframe bushings, ridetech strong arms/sway bar/tru turn with wilwood 12.19" brakes (.19 offset), Falken 265/35/18 tire and plan to run a 18x9 front rim. I've read numerous forums where Bret V has stated "5.5" bs with 275 tire on 18x9.5 rim with no mods required", I assume these numbers are based on the brakes having 0 offset? This info is great but of course my situation is slightly different. I did do a measurement and got 5.75" but I'm unable to verify by cycling steering or suspension. Anyone tried 265 tire, 9" rim and offset brakes?
