Well, fingers crossed, nothing to show yet, but to get Gp1 off the ground properly the right tyres are going to be needed. With the 'Goodwood initiative' hopefully resulting in more cars getting out to play (elsewhere) afterwards, it is important that it happens sooner rather than later!
What axle ratio choices do you have with the Dolomite? With an RS2 it would be possible to adjust ratio to suit tyre diameter- within reason.
