There's two trains of thought with the front suspension. They're both valid, and both work. But they do work a little differantly.

Soft springs and big bar: The soft prings allow the suspension to maintain contact with irregular pavement (which is the suspensions job), and allow the CG to shift to the front during hard braking. But the large bar controls body roll in the corners.

This works well in a bigger/heavier car. But not as well in a much lighter car like a Cobra.

Big springs and soft bar: The springs control the suspension, and control the body roll. The sway bar is used to fine tune the wheel rates for varying conditions. This works well with a light weight car (and especially on IRS). The down side is, it can provide a harsh ride on the street.

Have you calculated your suspension frequency yet? What about corner weights? You might be surprised at the recommended spring and bar rates.

Most track cars have a weight bias to the front. But many Cobras (like mine) have a weight balance to the rear. This really changes your set up. Sometimes people who work on Mustangs and MG's don't realize this.
