Some people have held 500 on STi's some people can't hold 400. It is all in the tune and supporting mods, make sure you don't have a super aggressive tune. If you are looking to go rotated, you should be fine with a 30r on stock block but a 35r would deffinetly be pushing it. A 20g or FPgreen would both be nice, safe, streetable turbo's though.
