Does anyone have the 17x9 RALLEY rims in the front with the VIPER calipers and 11.75" rotors? I just tried a factory 15x7 RALLEY rim onto a Viper caliper 11.75" disc setup (Dr. Diff) and the factory steel RALLEY rim hits the Viper caliper... won't fit.
I'm considering eventually getting a set of the 17x9 RALLEY rims (front and rear) and considering all options with the brake setup and rims... I may skip the Viper setup and just go with the cast iron Cordoba calipers with the 11.75 discs (I also have 15x8 minilight rims that just barely clear the Viper calipers... actually .. rubs the inside tape weights just a little bit... not desirable).... so, I want to keep with the 11.75 disc diameter for a few years ahead, if not permanent.
I'm aware the the 17x8 (and probably 17x9) Year One Magnum-style rims clear the Viper setup, as that was on the car (aka "SublimeHemi" Charger) which I just used for my inspection, etc.... The Magnum-style rims are flat on the inside vs the RALLEY rims curve and that's where they (15x7) hit the Viper caliper.
