Cobra suspension - eliminating lift/squat

[sambo]

Those who have been following my build will know that I recently had work done on the front suspension to allow proper adjustment of camber and caster, and to eliminate rubbing on the front guards. Now that the geometry is fixed I'm trying to sort out the spring rates and damping.

I drove the Cobra on the weekend for the first time since Winton, and with the QA1 shocks set to 2 for compression and 5 for rebound. Cruising along Melbourne's roads, this feels sporty but comfortable - about the same as my little Volkswagen GTI. I'm pretty happy with everything in that regard.

The problem is when I accelerate hard the rear end squats and the nose lifts - my mate who was in the passenger seat likened to to being in a speed boat. I can eliminate a lot of this by increasing the compression setting on the rear shocks but I lose compliance and the ride becomes bone jarring - as it was at Winton.

What advice do people have for striking a balance between comfort and "body control"? I have McPherson struts at the front and Nissan IRS at the rear.

Increase the rebound settings at the front and beefier springs at the rear? Different valving in the shocks?

Is there any way to approach this other than trial and error?
