my cat does doughnuts!

[autonm]

Apart from the SPUR/idler problems that I have been posting about, when it actually runs - it runs very well.

However when I turn into a corner it grips very well and powers out fine. However if I am a touch overstrong on the cornering the CAT literally does a doughnut!

I do not have to be going fast for this to happen, and even happens if I dont increase the power. Its as if the rear end is trying to swing by the the front wheels

Ive tried 40 and 25 in the rear suspension oil, didnt seem to make much difference. I have set the camber, ride height etc.

Ive even tried the same tyres on my B44 and the B44 does not show this doughnut'ing, so it isnt the tyres.

All screws/nuts/positions for the suspension etc are set to the middle hole.

If I reduce the turn on the transmittor then it loses's the ability to get round hairpins so I would rather fix the problem on the car rather than hiding it with a transmittor fix.

Any other settings I could try and change?
