I just wanted to make sure everyone knew of the rule change on the rear bumpers will be enforced at the ORP Race this Thursday. I would hate to see someone make the effort to race and not be allowed because they were unaware of the rule change.
New Rule:
All rear bumpers must be a multiple tube, basket style bumper constructed of SAE 4130 steel tubing with a minimum 1.0 inch O.D. and 0.083 0.095 inch wall thickness. ( See illustration # 10 )
Rulebook:
