A good set of tubular front upper and lower A-arms with the Guldstrand-mod, a larger sway bar, and a good set of shocks is a great start for the front. Most people would be extremely happy with this setup. Add a set of ATS spindles , higher rate coil springs and a quick ratio steering box and you are getting pretty close to what the aftermarket front subframes can provide. The front subframe is a rugged piece as is, it just has 60's era suspension geometry. The main benefits of most aftermarket subframes are geometry corrections, rack and pinion conversions, weight savings, and more tire clearance. Just think of it this way: if your subframe is in good shape, if you perform the above suspension mods and are happy with a 255 section width front tire, keep the front subframe and save money to upgrade the rear suspension!
Our new Torque arm setup is a great, all-around rear suspension. Torque arms tend to handle very similar to a 3 link when setup properly. They also work great at the drag strip (we have specialized in drag racing torque arm suspensions for 10 years in the 3rd and 4th gen market), and are very stable at high speeds (Hello Nevada Silver State Classic!) On top of that you won't believe how much better the car rides once you get those leaf springs off of it!
