I don't think the driftking drift at the mountain pass when he go against R34 in best motoring vol 6.
well I might be wrong, but from what I see, he didn't drift at all.
in that race he just trying to prove in mountain pass a well balance car is better than car that got power but not balance.
what he mean by balance is power, weight ratio IMO.
He win against R34 because in mountainpass where there are alot corner, a lightweight car can go through corner faster where heavy car must slow down.
