rack and pinion

I have heard firm feels box's missing parts needed to complete the iunstallation. I may be mistaken. BUT, a rack is lighter.

Firm Feel makes good products but you will pay for it. I used to run the stage 2 Firm Feel box and it was nice. IMO the advantage of a rack is the increased header clearance. With the stock setup your headers will run tight on linkage and the steering box.
