Scott, when I heard 10.5T motors I simply got worried (all panty twisted if I am honest) about a power race. I don't care about disparity between cars, the F1s will be quicker. I don't mind. But I do care about ever increasing speeds as that will take away from the fun of Clubman.
If it eventually becomes a class where the cars feel as uncontrollable as off road or TC then meh...
PS:
"tamiya non jelly moulds tubs, non ball diffs, little carbon, closed gearing wanting to see sensibly paced closed rubbing of nice body shells"
Nice body shells? That rules me out

Till I get my Camaro shell painted I'll be running the TC body

Boo for me I know...
