I would say to be competitive in Real Street you will need to run .30s and be on your game, but .50s arent bad and you may make it a round or 2. The top guys in real street are running 8.0s-20s and teasley just set a record at the last race with a 7.99. Every race Real Street bikes are just getting faster, its nutz ! I would run street et 1 and 2. Its a dial in class, and then you get to run sat. night and sun and if your dialed in on you bike you will go lots of rounds, its a fun class. Then if you are up to it have some fun and test on sat night in grudge racing just to make some more passes.
