Honestly I just want the self tuning aspect of the EFI. The altitude and temperature ranges I drive in mean my car is never quite tuned right for where I am at any given moment.
I don’t think you’ll have an issue with those wheels and the Viper calipers. The Mercedes CL500 rotors in that kit have probably 3x the offset from the WMS as the Corvette C5 rotors in the cobra kit. You can see in my earlier picture the viper caliper mount is actually behind the spindle, not on thr bearing side like the cobra caliper mounts. And the rotor goes all the way back to them
I’d love it, I was thinking about it when I was looking at trying to match up the front and rear pad compounds. The viper rears use a completely separate brake caliper for a parking brake though, make it a little more complicated.
