I personly think the TVS is the best bang for the buck without knowing what your budget or plans for the car will be.
I used polygraphit bushings but wished I would have used Delrin bushing instead. I also went with KYB shocks and now wished I would have bought bilstien shocks. They have bilstien shocks matched for just for the TVS system. I have never heard a complaint from anyone using bilstiens. I'm saving for them now.
If your brave enough to do the goldstrand modification that is a positive improvement. I did this to my car but never drove it hard before hand to realy give a testimonial. If you do some searches on it you will see it the best suspension mod you can do, or you can buy a taller ball joint or the AFX spindle.
I also went with a Lee power steering box and AGR pump. I sent in my factory box to LEE and they put in a 12:1 ratio gear. My only complaint is they did not change the torsion bar so I can steer it with my pinky. I wanted it tight and with more feedback. I'm sending it back in to have this changed.
I always loved thier SPC adjustible control arms. No shims needed at the alignment shop very easy to dial in your caster. Getting even more exotic is their AFX spindles.
So I hope this helps and you can learn from my mistakes.
