One thing to keep in mind there is that 8 pistons require alot of fluid. With that being said, you step on the brakes and the F/R proportioning is still the same and the front fluid gets spread out over a great area, which causes less force (less force, more area = same stopping power). Now the leverage (14" rotor) will cause a shift and in theory when you upgrade to an 8 piston caliper you should also upgrade to a larger master cylinder to keep the pedal from being mushy (ie, you have to push the pedal 2 inches to get it to even think about stopping because the 8 pistons require that much fluid to even think about moving). Also though, the size of the pistons will make a difference as well. Thus, there is alot to evenly distributed braking balance then just the size of the caliper. With that being said, for "total stopping capability" you compare surface area X total force X rotor diameter.......
