Looks like the SS 1LE tires need a different control module map than the V6 and SS. See this post. The pertinent quote from an engineer at GM:

“Confirmed that we do have two different cals (SS & 1LE) for the speedo. We will have different cals for the ABS/TC/ESC for the different vehicles as well due to the tire and suspension differences. The lowering kit for the SS is meant to work with the SS tires. Should a customer choose to put the 1LE tires on the vehicle, the vehicle will have speed and odometer errors along with less optimized Chassis Control Cals. They may even risk voiding the vehicle warranty with this change.”

Of course the Performance Suspension Kit is designed to integrate perfectly with your stock SS vehicle and cals, but it sounds like the 1LE wheel and tire change is more challenging than even I would have anticipated since there is no “factory” calibration solution available and you would therefore need to find a tuner for more than one of your vehicle calibrations.

I agree the wheels would look great but it sounds difficult to get the exact calibrations needed to realize the desired performance benefits you are seeking.

So, even though this may not be the answer you wanted, hopefully it points you in the right direction should you decide to pursue.

Thanks again for your passion for your Camaro and all your interest in the Performance Suspension kit.

Hope this helps!"

Since the car is going to be driven street-only, I'm just going to change the square all-season setup to a stock SS (non-1LE) staggered setup. The SS Goodyear F1 Asymmetric 3 ROFs in those sizes will present no difference in revs/mile at the front and only a 0.5% at the rear whereas the SS 1LE Goodyear Supercar 3s would be off 3.6% at the front and 1.3% at the rear from stock.
