I've just had a Brake Upgrade on my 996 completed at the Porscheshop UK. Thet fitted Braided Hoses to front and back, Red EBC Pads to front and Green EBC Pads to rear, with Blue ATE Racing Brake Fluid.
I was very impressed at the significant improvement in Braking Performance without the expense to going to bigger calipers et al.
I can recommend this solution if you want a little more on the brakes after upgrading your power output from the engine.
