So those "sport" pads may or may not be adequate for the track. It will depend on your driving style, but most beginners tend to drag the brakes and heat them up. At the first sign of fade you should do some cool down laps and/or come off the track. Also make sure you don't use your parking brake after a session, or say goodbye to your rear rotors.
SCCA track nights are fun, but if you decide this is something you want to do again I HIGHLY recommend doing events with an instructor. You don't want to let bad track habits sink in before an instructor can correct them. Or worse... never make it to that point
Thanks for the tips, I could certainly benefit from them. I've read about the benefits of making laps with an instructor, or paying for lessons with an instructor. I would love to get some laps in with an instructor, I wonder if they offer that at the SCCA track nights (I thought I read that...?)
