i have my 63 vette at 4 inches..96 inch length solid mount ( no springs)..
i have seen them set to low and un-load a car in a skinny minute.just in case anyone out there reading this doesn't understand the lingo ( un-load)..it just means when the weight transfers to the rear wheels and the tires start to hook (traction)..the wheelie bars if set to low will push the back end of the car up casuing the weight of the car to shift back toward the front causing the car to loose traction...hope someone got something from that...LOL..
