Performance suspension

[Vinniesempire]

Can I get some suggestions on a good performance suspension setup? I'd like to be able to road race my f-100.

for roadracing, you need to have a low vehicle. For our trucks, lower it, put in some stiff front springs, stiff gas shocks all around, front and rear sway bars. Have all new Urethane bushings put in on everything.

Fat Man Fab makes a sweet IFS set up for the front.

Just my opinion, but....

While anything is possible with an appropriate application of time and money, you have to remember that these trucks were just that....trucks! They weren't designed to take corners fast. The Twin I-beam suspension setup was designed to be rugged, to handle lots of weight and do be virtually maintenance-free (as long as you keep the kingpins properly lubricated). I'm not saying you couldn't make a few improvements over the factory design, by adding some anti-swaybars, some shorter/stiffer springs and shocks, etc., to help with cornering and ride quality, but these are in NO way ever designed to be a racing-type suspension. It just ain't gonna work. Plus, with the tall flat body, these are about as aerodynamic as a large brick.

If you're serious about wanting to do any kind of competitive racing, I'd seriously suggest getting an entirely different front suspension. The stock setup is just too heavy-duty (heavy!) and not even remotely road-course-friendly. The rear setup would work OK with some work, at a minimum you'd have to add a stiffer bushings and a Panhard bar to limit side-to-side movement.
