We are trying to make it easier for people to run in some TT groups without having a 5 point harness set-up. We used to require harnesses on ALL cars in ALL run groups. We have now relaxed that requirement.
If your car is year 2000 or newer (i.e., safer), you can run in Solo & Point-by with just factory seat belts. Older cars have older belts, may not have as much crash protection, air bags, etc.
We still want you to have harnesses if you want to run in Open Passing.
If you have cranked up the power or cornering abilities (e.g., competition tires, etc) we think you ought to have 5 point harnesses in Point-by.
Transponders are required if you want timing results.
Alfa and non-Alfa classification has not changed.
