Warn down half way yellow fullspikes
hard inserts...To press em onto the floor
camber links to longest so as minimal camber change
no anti roll bars at all
and dont make the presumsion that soft suspension settings/springs generate grip they most certainly do not!
and buy a durango....haha

jokeing
but these basic rules apply to all the cars at faversham that have been running indoors only weekly for about 30 years (alan Moon you are a legend)
hope this helps
