Sorry if I was unclear Silviadrifter, that was directed at Nitekids. I don't have any AWD cars on sim tires so I can't compare that, but my power for FRs is around 350 horses, though I keep an eye on torque too. If a car has a big, torquey engine, less power overall is needed.
Drifting on sticky tires compared to sims is completely different. I'm not sure which one I like better. Tires with good grip definately seem easier to maintain a drift, but sim tires allow more precision. They're both cool, one being fast and hard and one smooth.
