Touring Car legends doesn't look like it'll be ready until late this your, early next year, and no plans of a beta version either
mind you the rs500 is definately and awesome machine to drive!
Vanman, i run a Logetech G25 and i gotta say it's one of the best steering wheels available, with clutch break and accel pedals and full H pattern shifter it makes it more realistic, although i miss a gear here and there when i'm getting carried away haha
