(Amendments noted in BLUE - 2/24/11)
(Amendments noted in Orange -6/19/11)
General : TSR is a class designed for everyone! With a NO LIMIT on turbo, No restriction on Engine, No restriction on Trans, No restrictions on rear ends, pretty much allows anyone and everyone to be able to have a class to race in with as minimal restrictions as possible. You will have the stage engine guy's on street tires that won't be able to launch or use the trans brake like the guy's with the drag radials and trans brakes! this should make for some pretty neat racing...
1. TSR will be run with a “heads-up” pro tree start and off of a pro ladder.
2. No peer technical inspections relating to safety equipment rules by class participants or peers. The track safety personnel will make all final rulings on safety related items.
