Bah, NCCAR is like baby-butt smooth compared to CMP. I've run both, and there is no comparison. The reason NCCAR is hard on tires is because you are in a turn on 95% of the course.

I think Chad has some choice words about NT05s if I'm remembering correctly.


I don't know about Chad, but I sure do. I bought a new set of NT-05s for my Mustang because I was told they were decent and just happened to be on sale for $100 off on DTD. After 3 laps at CMP they were like glass and I sideways a lot. Yeah, NT-05s suck, at least they do for a heavy RWD with lots of power and torque.


On the Z06, I can only run Michelin PS2's or NT-05's because they are the only companies that still makes tire sizes that fit on all corners. The Michelins are gone in one weekend, the NT05 are good for 5 weekends. The Michelins have wimpy side walls and run multiple rubber compounds. The outside edges have a very soft compound. This makes them wear the edges off of on a car with 2 deg of camber. NT-05's are a pretty old tire and are getting hard to find. I'm going to have to switch to a square setup with 18 inch wheels if I want to run some of the more modern tires. Until then, the NT-05's are good enough.

Good to know. I've never been to CMP.

Supposedly CMP was going to get repaved this year but I don't believe that happened.

...add to that when people "drive fast" by hanging out on the right side of the peak of the tractive force vs slip angle curve, especially on that goes-on-forever turn. Tire wear and heat are what, twice, three times that seen when just to the left of the peak (and generating exactly the same grip).

CMP was going to be repaved just about every year since at least as long as I've been tracking a car.

+1. The track has been up for sale for at least a year now so don't count on any money being spent on improvements like that.
