Managed to run a couple of packs today with the car.
I flipped the rear wishbones to get the rear wheels as far forward as possible. This gave me only a few mm longer (instead of 1cm) than original and hopfully better weight distrubution. (Now F 36% B 64%)
It is very easy to drive and the only major drawback found so far is that I built it 2-3 weeks to late. (the week after the Nordic CC)
