If Tom does share his setup I wonder what rear wing he is using?
The set-up I was running at the weekend was the same as my southport set up listed on the cml website, on this page down the right side under "southport 2009" http://www.cmldistribution.co.uk/cml...tId=0000003600
However, that set up had lipo installed. At the weekend I was using NiMh batteries (don't have my race lipos yet) and the only change I make between running the 2 types of cell is using a stiffer rear spring, with lipo it is pink as said on the set up, with NiMh I use the stiffer orange rear spring as you note sosidge.
Giving advice for grass running is difficult as I have had very little running on this surface, grass only made up about 20% of the national track at the weekend. When I next run the car on grass I will set it the same, but it is likely that if the track becomes a little dusty, there will be a need to move the front shocks to the inner hole on the wishbone to give a bit more front roll and if grip is very low, possibly longer camber links all round too. Those stated shock settings should be fairly universal across a range of surfaces I think, time will tell.
As for my wing, the wing used at the weekend was an Edit 7" high downforce wing. No real benefit sought from its design, it is just made from a very strong and robust lexan.
