Schedule
Tech for GTP12 will close at 9:30 am. At the conclusion of GTP12 there will be 45 minutes till tech opens for OMG12, tech will close 15 minutes later. At the conclusion of every subsequent class there will be a 45 minute test period till tech opens and 15 minutes later tech will close for the next class. We will be following this schedule very rigorously, if you are not ready you won’t race, we will not wait for anyone. Waiting for stragglers is grossly unfair to everyone who manages to be on time. Class order will be GTP12, OMG12, G12, OM15A, 15A and OMO.
Marshalling
As always everyone will be expected to marshall the next subsequent race they do not race in. Cars will be impounded until it is clear that sufficient marshalls will be available.
