Sorry, I was out of town racing all weekend and just got back on here. My car is a back half car with 4 link. Fully tubbed, old school 4 link from the 80s. Not much adjustment. 32x13.5W slicks, dana 60 narrowed, 4.56 gears, strange axles, wilwood brakes. Front half of the car is an AJE front suspension, rack and pinion, no torsion bars, upper and lower tubular a-arms.
Now my dad's roadrunner has a split mono leaf spring with a ladder bar and housing floater. So does my friends roadrunner. Close friend of mine runs a true caltrac split mono leaf with the caltrac bar setup. His car has been 5.72 at 119MPH at 3385LBS. My dad's setup has adjustable ride height which was nice that he had it built that way in the 80s.
