FWIW I've been 1.33 60 ft. foot brakin and 6.15 @ 109 to the 1/8th slightly lifting and 111.78 all out so far w/old 5-ways in the rear and 90-10's up front..........John does/has suggested that mid 9 and quicker cars COULD benefit from double adjustable s but some still fly on the Ranchos..........
