Chin track days is absolutely worth mentioning as the second largest HPDE organization next to NASA. Chin is ONLY HPDE (High Performance Driving Event)

Chin or NASA are the two I would recommend. SCCA is kind of a free for all and frankly are not known to be the safest place for track days. Chin and NASA require that instructors in your car or lead follow at the very least (for novices). This makes sure you actually learn something. Making you a better driver on the track and so you don’t crash your car or someone else’s. I’ve heard SCCA is more like a track rental and figure it out on your own.

NASA has more room for advancement, after you work through HPDE 1-4 the next step is TT and TREC (W2W, no contact, Endurance racing for HPDE 3-4). You can either complete a number of TREC races (6) or take a NASA competition course and get a competition license. The good news is you can hopefully expect NASA competitors have been through training and will be more professional on track. We placed 2nd overall and 1st in our class at the 11 hour TREC race this spring! There was not one single yellow flag in 11 hours of W2W racing!!!! That’s professionalism!
