Convert HPI RS4 rally to touring car?
 

Hi I have a hpi rs4 rally that doesn't get used much and the nearest club has a tarmac track for touring cars which I fancy a go at. Does anyone know if the arms from one of the rs4 touring cars would fit on the rally and if so which ones?
I know I would need shorter shocks and drive shafts as well.

Cheers

Chris
