from a standing start,
what cause's it?
and after 5 big launches what tends to break?
and finally how do you stop it?

car is a 2wd, strong stage 3 circa 350bhp, lightwieght fly, paddle clutch, koni's, good rear tyres ( which were deflated to 11 psi for more grip ) and some spring assister's on the rear.

BTTT the car now makes noises from the gearbox and diff and has a max slippage speed of about 2mph. I think its done both diff and and transfer box.

 

you too talking about same car? 2wd dont have transfer box, Tramping is caused by control arms being able to move while under load along with beam and diff mounts.

 

would a set of poly bushes cure it?

 

No but they would help it,

 

what else can you do to help?
