I believe I saw you post that you're running 4.56? you'll most likely be between 2,500-3,000 on the interstate, which shouldn't be too bad. road racing you're in the powerband for extended periods of time (5-7k), which is what gets people in trouble from my understanding.
of course, if you put a lot of faith in mm, they claim that any IRS that is driven hard should be equipped with a diff cooler. if you're worried, I'd buy it for the peace of mind. I only have 3.73's but I'm not going to lose sleep over it, and I plan on racing occasionally.
