Originally posted by Rara: btw, calcs using some assumed numbers for piston sizes show the difference between the 278mm and 300mm rotors on the rear worth about 1.2% on rear bias. Compared to ~1.8% difference for a minor change in friction on the rear.
I'll throw out some actual #'s when I can dig up those piston sizes.
I calculated about 1% difference, I suppose that isn't much different than what you got, but I wonder why we have different numbers??
Either way, I did the calcs and then with actual testing found out I liked it VERY much with FSVT Rotors/pads on the front and with bendix Ti on the rear. Very good feel when braking hard and I even had the bad luck to do real life panic stop on them once where I was limited by the road surface and traction and the ABS kicked in. Otherwise, with the bigger rubber I had on the car I finally had awesome brakes.
