Thanks PappaDuck for all your help.
I can rule out anything being loose now.
The car has got pineapples.
When I think about it more I think it is suspension related.
The front end has to tendency to bottom out going over bumps and makes a loud bang noise.
If i remember corrrectly it all seemed to change after one drifting eposide. Mates have told me the rear tyres look wobbly and it kinds feels likr that a bit aswell.
I'll put it on a hoist and see if i can find something wrong with suspension.
