A weekend at a road course is $1000 in my eyes. When I've gone to Beaver Run and then Mid-Ohio with the BMW club. Both had instructors and they were about $300+ each for the weekend. My other $600 is in parts. Basically you are going to need new rotors and pads. And if you run street tires on a road course, there is a very good chance you'll be replacing those too. I was able to get through both weekends on the same tires, Dunlop FM 901 sports. Not the best tire either, but it did well for me. Let's not forget gas, at least 94 octain, I would have to think everyone would run that. Nelson Ledges sounds like the way to go right now. I think they have open track day once a month for like $175. Not sure on that though.
