Re: Stock vs Cross Drilled or Slotted Brake Rotors

Last summer I was guest at a club event at the local roadrace course. From what I gleaned though conversation and observation, there is no money better spent than on the brakes. A close second is suspension.
Run the best you can afford. Slotting and drilling is all about shedding heat to avoid the fade and warping you mentioned.
Ask club member what their prep/maintenance budget is on a per weekend basis for brakes, tires fuel etc. The answer may surprise you.

Common misconception. Slotting/drilling isn't for cooling. It is to remove the gas buildup between the brake pad and the rotor. Thereby providing better grip between the two.

Here's a quick write up on it:

And, in the case of drilled rotors, it reduces unsprung weight.

Isn't this just a couple of ounces? Is this difference even noticeable?

If I recall correctly, mild steel weighs .2833 pounds per cubic inch... so, depending on the drill pattern and size, it could reduce weight by a fair amount. When you apply that to the physics of the response time, it indeed makes a big difference.

In racing, every ounce makes a difference.
Save a couple ounces here, a few there, it'll add up.

Even if you add the same weight back with ballast, you can place that weight where you want.
