I agree. I think that if it is built right then the IRS will hold up just fine for the occaisional track day. I know I only plan on going to the track every once in awhile. Tires are too damn expensive! Plus there is a growing aftermarket for IRS as it is becoming more mainstream in the American cars like the GTO and CTS-V. If it is that serious I'm certain Moser or somebody will have a live-axle conversion for hardcore racers.
