I think that RWD cars should be used as the control. For example a 360kW Falcon GT (RWD) could weigh 1450 kg in race spec while an Audi RS6 with similar power but AWD could weigh 1500 kg. I'm thinking FWD should be minus 50 from the control and AWD plus 50. To keep weights relatively simple, I'd suggest that cars with over 350 kW weigh 1400 kg (FWD), 1450 kg (RWD) and 1500 kg (AWD). Then work on a sliding scale backwards as power gets less. Say -25kg for each reduction of 20 KW. So a 330 KW BMW M3 would weigh 1425 kg while a 330 kW Audi S4 would weigh 1475 kg. That should keep the power/weight relatively close while compensating for the positive/negative aspects of particular drivetrains. If a particular car was so heavy in production trim that it would never make the minimum weight, then perhaps some performance concession in the way of extra engine mods could be considered.
