I have built 2 cars with laddrbars both were amazing I could barely spin a 5" wide Bias ply tire with a 340 4 spd , it hooked HARD on junk tires , the Duster was nuts , 10" tires & 2-3' wheelstands even on the street with street tires , but when pushed in corners only the front would sway , it would pick up the inside rear tire right off the ground & you would hear it chirp as it touched back down coming out of the corner
