Ahhh.... the art of handbraking - one of my favourite past times a curse of the premature wear on my hand brake cable on my old scirocco and now has become annoying (adjusting the cable) on my 172 - the dealer must get suspect! anyway, this is how i do it: you need a healthy bit of speed up first, 30-35 mph should do it (or faster if you want) and whilst going straight grab the handbrake tightly (holding the button all the time whilst you do this, and dont let go of the button or else youll do a big burn out and wont go anywhere) and yank it up (going in a straight line at this point) as soon as the wheels lock turn the steering wheel (holding it with the right hand at about 10.30 on the wheel) and as soon as the back comes out release the handbrake back down and floor the throttle (first gear - thats why its only really any good at 30 mph), but make sure you release the handbrake as soon as the back comes out and make sure the back comes out with a violent steer of the wheel.....and accelerate away.......(thats how Tiff does it! and so do(did) I!)
