Here is our modified class setup from the last weekend. We both had a competitive pace, so it seems to work well on ETS carpet with high grip conditions and volante tire. Please note we are working hard on improvements for the future, so we used some test parts. Basically the biggest improvements were the green marked areas. Beside the prototype upperdeck and upper arm, everything is possible to adjust/assemble. Please check out the pictures too! The rod (upperdeck/motormount) is only necessary if you doesn't use the screw (upperdeck/motormount).
