Wow, sounds like you got the bases covered brother. Tire, shocks and big sway bar I guess. Short of cutting the front end out a putting in a rack and pinion system?
Waste of time really. All the rack and pinion accomplishes is getting rid of the worm/ball on-center “dead spot”. It doesn’t really help geometry or anything, and that assumes you do it right and don’t make the geometry worse. As long as the steering box is in good condition the on-center spot doesn’t hurt anything, not having it won’t make the car faster, it’s just how it feels. Now, if the box is worn out and the on-center dead spot is really large that’s a different story, but with a good box it’s not going to change much.
Same for the coilover conversions really. If you need the space for an engine swap and headers, oil pan, or you just need to have a rack and pinion you can go that route, but they’re just springs and shocks. Just like torsion bars and shocks, torsion bars are just springs. There are some advantages and disadvantages to both systems, suspension is always a trade off. I think it used to be a bigger deal because there wasn’t much performance handling aftermarket for the Mopars. But shock choices/quality, sway bars, torsion bar selection etc has all really improved lately, you don’t need to have custom parts fabricated to do autoX or road course stuff anymore. Hotchkis, Hellwig, Bergman Autocraft, Firm Feel, PST have it pretty well covered.
