drilled rotors are not strong enough to endure high clamping forces and subsequently crack under high heat. You actually need some material to soak up the heat and slots to get rid of the gas like mentioned earlier. Slotted is the way to go, if your still not sure check out brembo's website. We don't even use slotted rotors on our race car we just run 3in air ducts straight to the back of the rotors and that's stops most fade. The only time i've experienced break fade was at the end of a hard 45 minute session on a 110 degree day. Also don't forget about good high temp brake fluid, we use ate. They make an amber and blue, the reason being is so when you go to flush your brakes you know when you have fresh fluid in the calipers by the color of the fluid.

hope this helps

 

What are the advantages of drilled and slotted discs?

The main advantages of drilled and slotted discs are the same: increased brake "bite", and a continuous refreshing of the brake pad surface. Drilled discs have the additional advantage of being lighter and running cooler. However, there are certain pad materials that should not be used with a drilled disc.




Why are there so many holes in a cross-drilled disc?

The number of holes in a cross-drilled disc is part of the engineered system. Brembo has done extensive testing with regards to the number of holes, their size, their location and their chamfering. This attention to detail is what truly sets Brembo apart in the world of braking. The same attention to detail that is delivered to the Ferrari Formula One effort is a component of the high performance program. The number of holes in a disc is in part a function of the size of the disc and the internal venting (if it is a vented disc).

How does reducing weight of the braking system benefit the vehicle?

The mass of any vehicle requires energy to accelerate or decelerate. Reducing the vehicle mass improves acceleration, and requires less energy to be dissipated during deceleration. Rotating mass requires additional energy in order to increase or decrease its speed of rotation. Therefore, decreasing the mass of the caliper is valuable due to its contribution to total vehicle mass, and decreasing the mass of the disc has an even greater benefit due to the fact that it must rotate as well. Additionally, the mass of the brake system is also unsprung mass. Reducing the unsprung mass has the additional benefit of improved suspension performance, resulting in enhanced ride and handling.

incorrect, drilled are better at high temps.. hence why F1 uses xdrilled.

 

Its hard to say. Most of you are running street cars that really aren't that hard on brakes. With that said, WRC cars appear to use slotted rotors


These guys are so hard on brakes they have to water-cool the bitches. And then they still manage to catch the damn things on fire. I doubt any form of racing is as hard on brakes as these guys running on tarmac stages.

 

Aye, rally racing is hard, i saw the netherlands stage and by halfway thru the 1st stage the Citroen destroyed his front rotors from braking to excessively.

 

F1 cars seem to go for plain - at least the Red Bull car, but they use more exotic materials for rotors. Ceramic I believe. Personally, this seems like one of those things where everybody has a theory or maybe even preference, but there's no definite answer.

 

A different material goes a LONG way. Ceramic coatings have been used to insulate for various reasons. There are also many organizations dedicated to the advancement of ceramics and their usefullness. Hint = GOOGLE.

Also, notice these brakes are vented to allow heat to escape from the center of the rotor.

 

hahahahahahahahahaaahahahhahahahaha............... .hee whew, nice fake sig pic

 

Ha ha, fag.

That isn't my car.

Nice thread jack btw ass hole
