i think the cal trck syst is a type of snubber that runs a adjustable bar under the front spring kind like a ladder bar that allows movement one way but not the other allowing the susp to flex.(am i right or not)???
if i do end up putting traction bars on the car( i may have to as my susp is adj front and rear up to 8 inches and enough holed mounts now) i would keep them as low profile as possible and build a lower rearend mount plate that would allow only 1 1/2 inches below the rear axle and a narrow snubber in the front .
if i had a fixed susp i would put some kind of limiting syst up underneath as it would be out of site and above the axle.
its - 25c 10 below f here right now so lots of time to think about it till the snows gone.
