went to test & tune yesterday, 4/10 clay high banked tight corners. ran the HD bar right side, standard bar left side. Made a difference. Would recommend them for a 1/3 mi. track that we occasionally run, or a flat track where you would want it to roll over more. Next week we will run a 1/2 mi. track with the 1.25,bar I had made. The HD bar is 1.19
