cross drilled rotors Scott Williams is WRONG!

[jason_f_snow@nac.net (Jason F. Snow)]

Okay guys, so the best bet (when I need new rotors again) is to buy
stock and call it a day?

It's alright, I'm in the mood to correct some of the misconceptions, 
wrong info, and
authoritatively incorrect postings... :)

The answer is easy:  heat.

I really need to post this article soon I guess...go back and read 
what I wrote again...

Go bigger until it solves your heating problems.

What a bigger rotor will do is lower the overall operating 
temperature of the brakes,
which is a GREAT idea IF your temps are causing problems with other 
parts of the
braking system (burned bearings, boiling fluid, ineffective braking 
due to overheated
friction material..)

Here is the physics so easily forgotten by many people...the braking 
system does
essentially one thing:  turns kinetic energy (motion) into thermal 
(heat) through
friction.
