summer performance and autocross tires

"you may just be less competitive"

I am really in it for the sport and to drive the car,, buy there is no draw back to doing well either.
And yes, I plan to run the Cam-T class.
Our Indy area SCCA has an Autocross event called a Drag - Cross, it is as it sounds a mix of drag racing and autocross. Two cars line up side by side for a Christmas tree start, then after some length each turns into their own duplicate Autocross course. Should be interesting.
