A biiger brake system in not always the answer. As nice as these systems are one must look at the fundamental issue of why going to a larger rotor size benefits some cars but not others.
1) How often would the brakes be applied and at what speed would the vehicle be going?
2) How often would the brakes be applied?
3) Is the current master cylinder of adequate size for the upgrade and the intended use of the brakes to be fitted?
4) What is the speed window that the brake system is needed to operate within?
5) How much money do you have?
First and formost one must understand that a Porsche brake system is designed for a vehicle that operates in a level well above that of even a very highly tuned SAAB. Having more pistons in the caliper and a larger surface area on the rotor is always beneficial but there is always going to be an area where there will be dimishing returns. The AP Brake systems are nice but do you have hard DATA on the performance appliications versus better pad systems. Do not presume what works well in the UK will work well where you live. Proceed cautiously and calculate what size system is best suited for your needs. Keep in mind that disc replacement is a way of life and these do not come cheap either. Look into the features and benefits of cryogenics and their effect on brake components. Remember the velocity that you intend to operate your vehicle in is the factor that will effect the amount of kinetic energy you wish to disperse. How quickly can you dissapate the heat? How much does the current tyre/wheel package weigh versus the original tyre/wheel package? This extra mass has more of a direct effect on the brake performance then the overall weight of the vehicle. Decelerating a unsprung mass that is heavier then before can bring in premature brake fad. Changing brakes may not solve this if the the replacement brake system is compounding the problem. Cooling ducts and different pads are areas to explore. I am not trying to lecture you just giving you some food for thought and some insight.
