Great mod!
But! From the first laps I drove in Spa 4 seconds faster. I think this is too fast. It seems to me in real life slicks would not give such speed.
For comparison I tried to swap tires from SF70h, but for some reason the swap does not work in the current CM version (strange, because once I changed tires in this way on other cars). It would be interesting to compare tires from SF70h to yours.
I downloaded another similar mod. It looks like there is identical physics. The difference is that another mod adds Pirelli slicks visually also.
