What are the normal temps for track use, any advice. I'm starting stock, should i look into replacing brake fluid? Thanks

With these cars, 240-260 is normal for track driving. Oil temps sometimes crept up to 280 on hot days, but didn't give me any limp modes, though there's gotta be some adverse effects for running overheated oil in terms of wear and tear. If your oil went up to 260 w/ only a few hard runs, chances are you'll go higher than that at the track. See what happens.
Brake fluid - I'd say if you're novice, then maybe no, but if you're past that level, then get DOT4 fluids minimum.
