Quote from (SaM) :

You mean you wanna drift the road cars? Drift those. You dont wanna drift Race-spec cars, they arent meant for drifting and so they wont be a joy to drift.

Hopefully I'll find that out myself in a couple of days

I've only been playing the game for a couple of days now. Here are two pictures of my drifting session from this morning.
Can't wait to get my license so I can try some sideways action with the race cars... this is cool!
