An off-the-shelf part playing a significant role in Johns car is this Steeda five-link rear suspension. This $1,149 retail design eliminates the stock control arms in favor of Steedas heavy-wall steel arms in addition to adding an adjustable Panhard rod for lateral location. The stock Ford suspension binding is banished thanks to parallel upper and lower control arms, and the longer Steeda upper arms minimize pinion angle changes from full compression to full droop. A combination of metal rod ends and urethane bushings keep the system streetable while offering race-car control. At normal enthusiast speeds the combo provides good bite off the corners without axle hop, reduces brake dive, and generally makes things much more stablesomething John is definitely seeking.
