Need some serious input on swapping out my current rack/pinion

[PhillySpeedNYC]

After reading more in depth on my system it uses early 88-92 GM racks that are notorious for poor feel and failure. Many systems on the market seem to use the same design however I want something better and more dedicated towards performance. Are there any companies that can possibly fab up a ZF styled rack to my car? What are all the hardcore Ford guys using running auto cross or track events ? I can not find anything geared towards this and it's ruining my driving pleasure signifigantly
