Swing out.

Not knocking the guys with curved bars but neither the IHRA or NHRA inspectors here in MI would pass those to an 8.50. And several tracks the Midwest “CAN” have prickly inspectors at times. Probably one of the worst things is the inconsistency. But it does state right in the rule book that side bar must pass at a mid point between elbow and shoulder. Obviously not all enforce it, but if you ever drive 4-6 hrs for a race then get turned away...
