Rack and Pinion and other suspension questions...

[Dantigan]

I have been mulling over a subframe rebuild or aftermarket swap out on a first gen firebird. After crunching numbers the rebuild should save me about 1500 to 2000. Which would be nice to save for other parts. My undecided factor seems to be the steering. Most aftermarket subframes come with rack, and I know ridetech makes the tru-turn system. When looking at upgrading the stock frame to rack I see that speedtech sells the unisteer system that bolts to the back of the LCA. The speedtech subframe has their rack in the same location. I have seen many people say that installing rack on the stock subframe does not work well as the stock frame was not intended for it and the geometry never lines up. Aren't the speedtech control arms interchangable between their subframe and the stock one? If the arms are interchangable and the rack and pinion mounts in the same location wouldn't that make the geometry on the stock and aftermarket subframes the same? My thoughts are if A=B and B=C then A=C... Can anyone that has the unisteer on their first gen f-body chime in on the performance of the system. Would I just be better off sticking to the stock steering with an upgraded box? I am planning to go with a chicane kit, ridetech coilovers and AFX tall spindles. With these components in mind should I stick with the speedtech control arms as they are potentially designed to work with the unisteer system? I like the idea of using the ridetech strongarms to get a little more shock travel. Any input is greatly appreciated, thanks.
