Scarebird front disc swap-my experience
Agree with TimDart on the story.. it is always nice to hear how the job went, and how well (or not) everything worked.
With regards to braking systems, my figuring is like this. Every car I have owned has had adequate brakes. How do I know this? Everytime I pushed the pedal down the tires locked up (well there were SOME instances when this was not the case, but that was thankfully only temporary :) ). To me, this indicates that my brakes were able to overcome the force of the road and the tire, and stop the tire. To get better stopping (to allow more friction before the tire slips) use a stickier tire.
I dont think I need a bigger caliper/rotor if I can lock the rotor between the pads, but I sure want pads that retain the same friction, with no fade, whether hot or cold.
Everything else just needs to be balanced so the weight shift during braking can be controlled, especially to keep the A's little rear from coming around. Pedal adjustments, master cylinder size, all can affect feel, but I dont think they make the car stop faster.
Of course, I am thinking of a nice, shiny aftermarket kit for my Demon :)
