You are going to need tubular upper arms to achieve enough positive caster. Global West arms are pretty cheap if you get them bare. You need the type of cross shaft that has male studs on each end, not bolts, - the bolt type will come loose.
Yes the "lightweight" lower bushings are Delrin.
A rear antiroll bar may be needed if you use a rear leaf spring in the 175 lb range. If you go with a 250 lb rear spring, you probably won't need the rear bar. This assumes you have close to 700 lb front coils, and a 1" solid front bar or 1 1/8" hollow front bar.
If your horsepower is 500+, then the 250 rear leaf package may be better.
I'm less happy with Hotchkis leafs after using them on my wifes second gen. The pinion angle went way off when we installed them and I had to use 8 degrees of shims on the axle to get it corrected.
We just installed Global West 240lb leaf springs and only had to use a 2 deg shim.
The Hotchkis did ride pretty well and would make most people happy as far as rate, but we open track and autocross this car a LOT and felt like we needed to try a step stiffer.
