Depends on the event but most non SCCA rally’s I’ve attended had you keep the windows closed to keep debris from intruding into the cabin. I’ve never raced an SCCA rally event though. Hillclimbs around here are mostly tarmac and windows are down. It’s no Pikes Peaks RTTC event that’s for sure. Canada, well that’s a whole other bag of tricks up there.
Epic PP video from '90. A must see. World record run. I do not have this type of balls but it’s nice to think.
Just read over the SCCA rules for M4 RX classification(Modified, AWD). Safety Rule E:
E. The driver’s window may not be down more than 1” during course runs unless
the vehicle is equipped with a window net and/or the driver is using arm
restraints. The same restriction applies to the passenger window if there is a
passenger.
So SCCA does allow windows down during their rally cross events if the rule above is followed. I still have to get the new rules for the cannuck boys up north.
