Cheers guys for the suggestions but saddly they have all been covered
Nick, you saw the diffs at Broxtowe, they are like silk mate and the slipper is letting go when it needs to. I am running the LAW36 on the chassis and currently having to run just about zero antisquat to be able to drive the thing at all (makes me nervious as to what it would be like if th heavens opened).
Matt, I'd like to run a shorter rear link to get more square up but none of that matters if the car is facing the wrong way .... it is litterally that bad! I am running a #75 front spring on carpet anyway ... always have. Currently 2mm under front inner ball to help calm it and all the other front end settings are subdued too.
It is definitely the rear as even when just coasting through a corner the rear is breaking away ... in fact that is when it is worst. Also the fact it is killing rear tires tells me it's not working them well at all, the fronts are lasting as long as ever.
I am trying to use the roll to generate some grip from the rear, yes that is a big compromise but it is all I had left to try!
I think I am building the answer I need here .... those of you guys who are happy with the car are very happy ... those who aren't are struggling a lot. I REALLY liked the FS, always suited me I though but I think the FS2 might be a step too far for those of us who like a planted car (that said I've just thought about droppign some extra weight under the cells .... cogs are turning).
I'm going to start playing tunes with the rear end combinations to see what I can achieve as and when I get chance, wrong time to be working away for 3 weeks hey
