(dont remember who's, but in-game he calls himself B.OverDrive or something)
and my problem was locking up the frontwheels while trailbraking.
When I read your comments about applying gas beeing valid for not loosing
the rear, I moved the brakebias backwards, and it seems to work pretty good.
When I drove yesterday, my last lap was a decent 3/4 lap to gravelpit, but I
did drive _very_ smooth with brake and gas, just like gpl, and it did work
very good. Now I just need to cut 2,5 more seconds...
Thanks!

(I think the F1RC physics is pretty gpl-like, just without the visual
chassis roll.)
