Hardbar has just announced a 3 lb Harness Bar!!!!!
It is a Low weight Carbon Fiber Bar with Aluminum Tips weighing in a 3 lbs. !!!!!!!!
Traditionally the advantage of a harness bar was to reduce weight in cars that did not need a rollbar/cage system....but still needed a harness attatchment point with added chassis stiffness.
However, they were still 40 some odd pounds that were mounted up high above the roll center & CG.
