Hi moog, glad to see you getting on with things, the easiest way to set up front to rear balance is with bias pedals, or at least, the more forgiving way, otherwise, for a serious circuit car at least, its probably best to overbrake the rear, then you can add i bias valve to tune the set up for dry running with a setting around the mid point of the valves range, that then leaves you scope for optimum wet/rain bias with more to the rear, some like a rotary valve, i prefer a lever type for quicker more positive selection on the fly, down side is they can be knocked out of desired position unnoticed, put the valve where it can be seen, not behind the seat,,, dont ask,,,. its also important not to overbrake a track car because brake temperature controls Tyre temperature, bugs need all the help they can get with that aspect, especially with the front, its a big problem on long tracks, tho' not many are left thanks to nanny state ways, thank heaven for thruxton.. good luck with it, Johnny.

Good to here from you Johnny, and good to get tips from a seasoned pro. I was thinking of a Rotary bias valve in one of the centre dash holes, or would you suggest down on the centre tunnel near the gearstick / handbrake? Dash would be easier to reach but mounting & plumbing would be simpler on the tunnel. I take your point about a lever type being easier to select and adjust and also easier to reset repeatedly to the same settings, in which case on the tunnel is probably best.

Question for you: When i looked over your car at Apex last year i saw you were running 944 spring plates. Do you use the 944 torsion bars as well? And what torsion bushes do you use? I think you had trimmed down 944 end caps as well to retain everything - yes? I have a set of 944 plates/bars/caps i could use but at the moment I have my own adjustable spring-plates in place that take the short torsion bars and (at the moment) 24mm bars. Any reccomendations?
