Drilling Factory Brake Rotors

[SRT BEE]

I was thinking of having my stock rotors drilled to improve the looks. Has anyone done this? Any ideas if it would improve stopping performance or not and do you think it would affect the longevity or reliability?

Well, by drilling, you decrease the overall surface area. It is like making the pads smaller by the amount of area that is removed underneath their contact patch. I don't know whether it would be perceptible on the street.

The holes can cause a problem with longevity; but mainly on tracked cars which see very high rotor temperatures.

I drilled stock Shelby rotors on a couple of my Shebly (Turbo) Chargers. Rememmber that they also have to be countersunk,not just drilled.

I felt a difference on the street. The pads won't last as long. I had no problems with them, but that was not racing driving.

On my Viper I bought 2 piece lightweight rotors and the fronts are slotted Roe Racing 14" since the drilled rotors have a tendency to heatcheck (OK on street).

Did the same thing, only driven on the street, no problems.

It will not improve stopping performance or cooling. It will decrease the life of the brake rotor, and possibly the pads as well.

If you really want the cool looks I would just spend your time and money and change to the 2 piece drilled and have a real quality product in the end. I can help you get a great price on the Euroteck rotors if you want.

Why go through the hassel of getting them drilled? If you don't track the car, check out ebay there are all types for sale there. Do a little checking to find some good ones and just replace the stock ones.

E Bay has its place but it is not going to be on my VIPER. Sometimes we can't see the forest for the trees.

If you drill your rotors stay away from the track. If you don't, you just might get to drill a wall too.

There's a lot of engineering that goes into a braking system and going at it with a drill will not improve them. They may look better but they won't work as well.

I bet I've seen at least 20 cars have rotor failures (at the track) after drilling them.

Just be careful what demands you put on your customized rotors.

One more thing. Make sure that every part of the pad sees a 'hole'. Otherwise the pads will wear unevenly. Also be careful where you drill with respect to the cooling vanes.

My slotted and drilled Eurotechs are great!

Pics speak a thousand words Do Not do it

Slotted rotors are better and safer

Fats, whose rotors are those? Manufacturer?

The first pics are EBC Rotors using Hawk pads!!! They were being used on a track day!

The last shot is of my old rotors 'Bayer eradi speed 2 pice rotors' I spoke to the company about the cracking, they recommend Slotted Rotors for track use, the slotted and drilled look is ok for street, but Personally I would go for the slotted

Heres the link for more info about the first pics

Looks like the last one is Eradi Speed which is made by Baer I had them on my 04 cobra never had a bit of problems like them look like.

If just for looks, you might consider just dimpling instead of full drilling. (still a bad idea for performance though)

If you're gonna pose at least get a real two-piece rotor. Drilling a one-piece screams tacky.

Thanks for the thought guys thats why I posted. I will order a set so I think I will look into the Eurotech's or something else any suggestions?
