What is a SCCA TT Spec Roll bar?
SCCA roll bars are defined in the SCCA TT Rules Section 18.2. It must consist of a main hoop, two vertical supports and a diagonal bar. The Roll bar should also contain a horizontal bar for mounting the harness straps. Most OEM “Show Bars or Roll Hoops do not meet this requirement. We require that all Time Trial bars be inspected and verified SCCA TT Level 3 or 4 compliant. The Tech Guide is kept up to date.
