I run a TCI pro tree brake. I started with a 53" IC that was about 8.5" above the ground. That setting seemed to work well bracket racing with the sbc on nitrous but didn't lift the front. With that setting, the lower bar is angled up in the front. I tried moving it down one hole in the front while in Tucson, but it didn't change much. It has a 61.5" IC at 6.7" high. At that setting the lower bar is still angled slightly up. I really thought a longer IC would help it lift the front but it didn't change....
