i see all these bigger rotor upgrade kits and what not, but a LOT of them seem to be so big, the caliper cant bite the wole rotor. if this is the case, what the **** is the point of the bigger rotor? am i missing something?
just spend the 2.5k on a big brake kit, and you will no longer have the small caliper issue. Just kidding upgraded rotors, lines, pads, and mcb is all you usually need for street, i love my brembos but i dont like paying 255$ for a pair of pads.
Don't forget the master cylinder brace. IT is the biggest improvment to braking performance second to pads. More than brake lines or rotors. For most street apps you want the one time stopping power, and not worried about boiling off the fluid.
Imagine a record player (turntable) turning at 33 rpm with a 12" LP on it. Use a finger to press down on it about 2" from the edge (or for more dramatic effect, close to the center) to stop its turning.
Now use the same finger to stop the turntable at the edge(rim ;o) ). It now takes much less force to stop it while using the same finger (caliper).
zlover57 is correct too...more material to heat up means cooler braking and therefore less brake fade.
We did our upgrade for $300. Until I'm ready to spend $1500 on the next level big brake kit, I'll live with the funny wear and spend the $1200 saved on something else. I will be painting my unused rotor band with black 1200* ceramic paint.
