in the prior track car I ran Sport Cups for a few years. They wear like iron. Ran 1 set of the R888s. Liked them both. The Cups and R888s seemed pretty equivalent. Of course ran both on a car that is 600 lbs lighter than the ZL1. Both were about 3 sec a lap slower for me than Pirelli slicks at RA. Just curious how the stack up to the presumably lower cost GY 3R.
