Well what a difference that made, changed to red springs and 35wt oil, bought a camber gauge and set that up properly and set ride height as you suggested, it was honestly completely transformed and an absolute pleasure to drive, at least for the first half of the race anyway. I have a feeling that the smaller holed pistons that I am using was causing the shock oil to get a bit hot as it got a bit of a handful after about 10 mins into the final so am going to go back to standard pistons for next meet. Mechanical failures prevented me from finishing any of the qualifiers but I did win my final heat bumping me into the A and then finished 5th in the A final so all in all a pretty good result and with even more to come I think with another few tweaks.
