Its a good place to start if you're interested in trying out time trials, and yeah TT is time trials. Time trials, call for extra safety gear, suit, SA helmet, roll bar, etc.
Sounds like with TT more risk is involved since people with push their cars more to get the best time.
HPDE is something that I plan to do, hopefully I'll get to do one this year at least.
