What do you know that every single race team (amateur or professional) do not???

Slotted, drill rotors dissipate heat faster and more effectively. Heat = fade, fade equals crash. If you add high quality brake fluid to the mix, you have eliminated another weak spot that causes brake fade (I use ATE DOT 4 and alternate between Gold and Blue). This way when you flush and see the color change you know your done! Flush your brakes once a year and you will have NO issues with moisture. Add SS brake lines and a master cylinder brace and you now own the best braking system money can buy, that also has great pedal feel.

Overkill on a DD? Not when I am running with my kids in the back and some idiot pulls a move I avoid by feet! Money and time well spent IMO.

so are we talking about racing, or are talking about driving your kids around?

also i dont know about every race team, but i know race teams and people that race, and there are just as many competitive guys running blanks as there are drilled. So either the one side is REALLY good or the difference really is negligible.

proper cooling ducts will provide for more heat removal than dinky little holes, disks are already vented!

You should not run slotted or drilled rotors on a daily driven car.

Drilled rotors are done to save weight for race teams because the rotors are so big. Also, all of the race teams that use drilled rotors are sponsored and put brand new rotors on the car after every race. Go check out other race teams in the Koni Challenge Series... most of them do not run drilled rotors. Plus drilled rotors on a DD are going to crack eventually, have fun with that happening with your kids in the back.

Here is a thread that helps explain it as well: http://www.8thcivic.com/forums/suspe...dissolved.html

I have to agree with this. DD car. Std rotors, not slotted and definitely not drilled. On the street it's all about the initial bite, quick response in case of emergency, not about repetitive abuse like on track.

This is the oldest rumor on the street. 1st of all, old 'drilled rotors' did just that... these days 'drilled rotors' are NOT drilled, but cast into the rotors and WILL NOT crack. They will vent both heat AND water better then non-drilled rotors. Yes, they are also lighter (less material) and therefore help reduce unsprung mass as well, the worse place to carry weight.

So, what you're saying is if you are running the best braking combination you can buy, you are a threat to loved ones and innocent driver's when you use them on your daily driver... because the disk will explode?

That's funny almost every brake disk in the Mercedes-Benz and Porsche line up are 'drilled' Somebody better go warn them that they are not designed for daily drivers!!!

I need to find the picture of the Crown Vic where the rotor is completely gone except for the outer ring that the caliper didnt touch. Its pretty crazy.

You clearly didn't read the link. It doesn't matter if they are cast or not.

"Explain again just how drilling away material/structure from a CAST product DOES NOT weaken it? Since you are obviously a man of great knowledge and experience surely you have seen what can happen to a x-drilled rotor on track right? Yes it can happen to a non-drilled rotor as well but the odds are in your favor when pimpin' bling-bling drilled y0! Since you are also an expert on thermodynamics why not explain to the group what happens to a cast iron molecule when it is overheated. I will give you a little hint - the covalence bonds weaken. These bonds are what hold the molecules together boys and girls. You do the math - it adds up to fractures."

Yup. Do you plan on replacing your rotors every week? Dou

Because guess what... they are cars ready to go on the track and not meant to be daily drivers. Get a clue dude. The biggest surprise is they are mainly on there for looks.
