Rotor Pros - What do you think?

[dontlifttoshift]

There is not an appreciable difference in cooling between drilled and non drilled rotors. Rotors cool through the vanes from the center out. Air would have to turn 90* into a spinning rotor to cool through the holes you drilled.

The idea of taking a rotor and adding a bunch of places for it to crack just doesn't make sense.

Great info!

Don't the drilled help with cooling as well?

How much faster will slotted eat up pads?

Is there a different brake upgrade you would recommend? My front brakes are 4 piston I believe (I got the GT Premium; NON performance) and I been eyeing the Brembos, but they are on ebay for 4 to 8k!!!

Most people are not pushing their car hard enough to ever warrant drilled. Yes it can aid in cooling in extreme situations. For most situations people would see no benefit. Drilled vented the gases from asbestos brake pads when they were used. It was for gas venting, not cooling really. Id stick with slotted. If you are having brake fade, upgrade the fluid. Pads, fluid, slotted (at most) should be enough for a large portion of owners. The more extreme will do brake duct work and SS lines. Someone sells a brake duct vent for the S550 already, Like this . http://fulltiltboogieracing.com/images/FT%209215%20Kit.jpg Actual kit price here. http://fulltiltboogieracing.com/2015_S550_Brake_parts.htm
I would use centric (they are made by stoptech) once they are available. Very comparable to Brembo blanks, and cheaper. Any decent brand name slotted you should be fine though. While DBA rotors are amazing, theyre overkill for most people.

Oh, as for how much it will chew up your pads, it really just depends how aggressive you are with braking. Im sure that's not the answer you were looking for. Kind of hard to put a mileage estimate on how long they will last. I would buy carbotech pads and get some good fluid and leave your rotors alone.

Agree with everything here. The crowd that either doesn't fully understand the dynamics of braking or just want the look for shows or whatever love to get those cross drilled rotors.

A good set of pads, ss lines and a fluid change will upgrade your braking performance significantly. If you must change your rotors, go slotted.

And I've used rotor pros before, they're solid.

get better tires to improve your braking the most. Pads and fluid is more about brake feel

I admit and always have. I am doing it for aesthetics.

Unless they are close to stock rotor prices they likely aren't worth it. I personally won't run any "cross drilled" rotors on my cars but I will run them if they are cast holes, much more costly.
Slotted rotors on the other hand are beneficial but not a huge difference, will shorten pad life under hard useage but they help to clean the swept area of pad dust while under use to they will have a little better bite to them.
On my track M3's just using good stock rotors with good pads and fresh ATE super blue was perfect and those were only 2 piston calipers ;)

Where does one get rotors with cast in holes?

Rears shipped yesterday and the fronts will ship Friday.

Received my rears today.

These are Ford Parts that are drilled and slotted. There is a Ford part number engraved on the rotor hat like the OEMs on my car.

Same here. Before I hit Pacific Raceways in Seattle I will be getting their rotors and Carbotech pads. Money exchange is going to kill me though $$$$$
