I have the feeling that it is caused by the front having no lsd, causing the inside front wheel to loose traction. Does a front lsd cure the understeer at corner exit? I suppose the lsd shouldn't be too tight, as otherwise it will cause understeer on turn in?
It's quite a while back, but I came across this topic again. The understeer has been improved by fitting a thicker rear arb. At first I tried a 21 mm arb of a Scorpio (bug-eye) 24v, with rosejoints instead of the normal droplinks. But that actually made it oversteer quite strongly at one moment that I nearly lost it. So currently it has a 20 mm rear arb from a standard bug-eye Scorpio with standard droplinks.
