We run any assists we like so pick and choose, but we all run SRF on race night as to lower the skill barrier for newcomers and also keep the racing fun for all, we do factor out the SRF in our reviews mind you. Also we have a few ground rules in place. No honking the horns during the races. Contact is expected, but any contact with malicious intent is not okay which will be subject to review by a jury of your peers. Basically those two rules can be summed up in one sentence, Don't be a Dick. Another rule we have is the 'Any Given Sunday' rule, when active the race winner has to drop down a tyre compound so SH tyres to CS tyres and if they win again, they drop to CM's and so on. In the event a AGS race is won on CH tyres, other means of handicapping will be enforced, like no SRF, ABS or if possible, a PP handicap by power limiting. But aside from those basic rules, it's all good fun and racing. Oil changes aren't mandatory, but are highly recommended. Visual upgrades like paint and wheels and race numbers aren't considered tuning by PD so they are allowed, but wings,flat floors and body kits will need to be removed to clear the regulations. My advice? If possible, buy a fresh car to remove all concerns of tuning and work up from there. And here's a not so secret tip, Brake Balance CAN be adjusted without violating the no tuning regulation.
