from the various writeups on here, nasioc, and scooby moods, ive got all the know how and what not, but i have a question about the physics behind this upgrade.
it utilizes the same WRX caliper and pads but with the bigger outback/legacy rear disc via the rear mounting caliper bracket.
but since the pads and caliper are the same size as the wrx wont the contact surface of the brakes to the rotor be the same just on a bigger rotor? it seems the same force and contact patch will be applied to the rotor from the brakes.
i guess i need a quick physics lesson to understand why just a bigger rotor without bigger pads can create more stopping force. logic would dictate you need bigger pads to create more "clamping" force
i know i can get better pads and such. but for the questions sake, lets say everything is OE
if anyone can help me out would be awesome
thanks!
