It will be interesting to see the amount of torsional flex in the chassis, as this will largely dictate the cars performance on wood vs. plastic tracks.

The generally accepted principle is that low grip surfaces (plastics) require soft and flexible chassis whereas high grip require stiffer chassis. 
I visited Luton Wood track recently and the experience of trying to drive a soft (blue) chassis suspension NSRMosler on wood seemed to reconfirm this.
Soft chassis suspension cars dig in, shudder and are hard to drive on wood tracks.
