im sure duncan from nsw can argue this point
i believe there should be a handicap system based on wat mods will give u time gains on the track. but that would b too complicated to divise unless someone wants to sit down n work it all out. this would mean that a stock gtst or even n/a gts could compete against the likes of snowy for a club championship and would bring the driving aspect into play alot more
as i sed it is prob too hard to guage wat a mod would b worth on a track or as a % of a lap time
