Thank you sir. So you run 20 PSI in the rears at the track?
How much heat?

I will never track mine. I run cooper all season. They grip about as well as the original goodyears. But thats OK because I like spinning the wheels sometimes. Mine also a manual. I can goose the throttle a little in either 1st or second gear in a roll and break the tires at will to get the rear a little sideways all still will staying within the speed limit. In Torque We Trust!✊😆

295 would be about right. I have a 305 on the stock rim and it's a touch wide. Only did that because the original 555r fit perfect in 305...so the 555r2 run a bit wider.

Yes just 20psi and just getting them smoking is enough for a great launch. Make sure you drive thru the water and stop about 2 feet after the rear tires pass the burn out box. Then do your burn out. My best is 1.56 on my C7.

Another vote for the 555R2.

I put 315's on 11" rims and they hook at the track. On the street they still get loose once in a while with a more or less stock M6.

Massive improvement over the 245's. W/O TC it was like driving on an ice skating rink.

As a side note, they do leave a rubber dust all over the back end of the car.
