[QUOTE="Black Cobra '99, post: 16180572, member: 138833"] Torque = Pressure * 2 * Piston area * coefficient of friction * rotor dimeter You increased the rotor dimeter from 14" to 15", but you also decreased piston area from 4.3 to 4.26. So, with everything else the same you end up with only a %6 increase in torque going from the 4 pot to the 6 pot. One more thing to note about balance is weight transfer, brakes system are designed around how much weight transfers from front to rear when braking and so that additional weight needs to be accounted for. I'm not familiar with rear brakes on the 15 but I don't see why this is important to this discussion. The 15+ and GT350 front brakes are very similar, and in the case of the GT350 the real effort was put into making the whole front end rigid enough to get a better braking feel, for example the caliper on the GT350 has a bridge as part of the cast while the 15 has a steel bolt. Yes, there is such a thing as too much brake. The evidence to that is find me a car that cannot lock its wheel under heavy breaking, and I'm talking about sports cars with high gripping tires. Again, StopTech covers much of this and they know what they are doing. [/QUOTE]
