Hi Paul, Best thing would be contact Richard or Sue Mallock, they can give you all the advice you need,give them a call on 01604 4863504, Regards Colin,
Paul, you also may want to consider Cup, pretty much the same chassis, probably lower running costs due to running a road engine rather than tuned one
Just a quick note to say thanks to David Childs and Jamie Champkin for their offers of help and to Sue at Mallock for her time / responding to a lot of questions! Thanks Paul
