We are bringing back the 10L class in Ohio this year at CORCAR. We are looking at 4 cell stock with the GTP/GT style bodies. At this time we have chosen 4 cell because our black top is a little ruff and we hope with less weight, the tires will last longer. We've talked and said if we need to we will also start a 4 cell 19T for anyone that needs more speed
As for a body, McAllister makes a 190mm called The Flying GT that looks a lot like the old ProtoForm Mercedes CLK. The only place I've found this body is on Ebay.
