[Nimbus117]

What works for me on our tight, twisty roads in the dry is to decelerate and change down to your corner entry speed. Then apply a small amount of throttle to preserve the balance of the car through the corner and nailing the apex, then hold off until you can see the corner exit where it's obvious you can give it full throttle.
If you really want to know how to drive your car, sign up for one of the Porsche Experience days such as the ones at Silverstone. For £250(ish) you get to drive the latest Boxster, Cayman or 911 and you will have a blast. The instructors are amazing, really show you how to get to the cars limits (and beyond) in a safe environment.
