I run 245 Front / 275 Rear NT-01's for track events. These are designated as R comps, but are not really any stickier than the top shelf street tires like RE71 R's.

I had rather run a 255 Front / 285 Rear, which I have run in a Hoosier a couple of years ago, and they worked great. The problem I have is that you can only get good sizing for these in a Hoosier and ZII, and I really don't like ZII's, as they overheat too quickly.

Bridgestone does make a good low profile 255 F/285 R in the RE71R, but it is currently only available in Asia. I am hoping they will bring it to the USA for next season.

You need to pay attention to the overall diameter of the tires before ordering. Our cars are already geared way too tall, and larger tire diameters just exacerbate this problem. I had rather give up a little width in say going from my preferred 285 to a 275 in exchange for keeping the diameter down. Unfortunately, this compromise is way too frequently required.

As others have said, you need to be careful about what will fit on your car with your particular ride height, camber, etc. Take lots of measurements, and pay close attention to all of the manufacturer's dimensions.

Good luck.
