from what i gathered, race car drivers first started using drilled rotors to dissipate heat away from the surface and allow cooling. but then they realized that drilling or not drilling them properly causes the rotors to crack easily...espeicially in the high stress factors that the rotor is subjected to during racing. so now most race car drivers use slotted rotors because they can withstand the heavy braking longer than cross-drilled rotors. but the above is only true for race applications

"drilled" rotors are not infact drilled, but rather formed that way (which is why the real ones don't crack). and none of this was to dissipate heat, but rather to get rid of gasses which were caused by older brake setups...

That's not exactly light. Sure it's kind of light for 18's, but not by any means light. Also, the brakes helping you in the rain? Come on, do you actually believe all of these rationalizations?

Drilling and all equals less space for your pad to contact your rotor, which means less brake performance, plain and simple. Why not go for a full big brake kit? You have big enough wheels for it.

why doesnt that sound right to you?
edit: thats what the dealer said when i spoke with him on the phone

You really think that some guy working in the parts department knows that off of the top of his head? haahahhaahahahhahahahaha! quite unlikely (though possible). Tell me what brembo would do to make a caliper the same size weigh less (besides slotting and drilling that they didn't actually do)?

I am going to put single piston disk brakes on my Valiant,prob this fall.

The stock drum brakes are just not good enough!


Caveman.....The only other person on these boards who knows wtf he is talking about when it comes to muscle cars.

Ya cave, mmm 4 wheel drums, justa MC no booster on the goat. Talk about ...scary....

I just got these EBC "Green Stuff" pads and a set of their Slotted and Dimpled Black Annodized Rotors for my '92 Mustang.

I already have the stainless steel lines, brake proportioning valve, upgraded calipers, and I'm running cross drilleds on there now. I haven't had any cracking with the cross drilleds, but I've gone through 3 pad changes with them, had them a few years, and they can't be turned, so I'm replacing them this year. I've been lucky I haven't had any cracking around the holes yet, but I'm not waiting. Usually when cross drilled start to go, they will actually break into pieces if you aren't checking them for cracks, which is why I went slotted and dimpled, as opposed to full cross drilleds, this time.

anyways... the mods are looking great! once you get those calipers (and paint them red!), are you done? are you planning on any more mods??? i wish i was modding, but i cant afford to drop that kind of cash.....

again, the gti is looking sweet!

(Amused response is the best so far).

thanks ronnie. these people love to assume! what a bunch of e-thugs :p

from here

Brembo Sport drilled brake rotors are for drivers who want to improve the looks and performance of their vehicle?s original braking system without having to change additional brake components. Brembo Sport drilled brake rotors provide excellent stopping power in everyday traffic, as well as more spirited, high performance street and highway driving.

Brembo Sport drilled brake rotors match the vehicle?s original equipment rotor?s dimensions and are fully compatible with its hubs, brake calipers and road wheels. Front and rear Brembo Sport drilled brake rotors are available to provide a matched appearance on all four corners of the vehicle, and employ one-piece vented or solid rotors depending on the vehicle?s original equipment specifications.

Starting with select castings, Brembo Sport drilled brake rotors undergo the race-born practice of cross drilling to provide multiple paths to disperse built-up heat and gasses. The Brembo Sport rotor?s cross-drilled holes are bi-angle chamfered at the rotor?s outer surfaces to help reduce the cracking caused by repeated, high stress, high temperature brake applications. Brembo Sport drilled brake rotors are sold in axle pairs.

Brembo Sport drilled brake rotors are coated for corrosion resistance to help eliminate rust and to offer a bold, aggressive appearance to enhance the look of the vehicle?s road wheels.

OH TEH NOEEES!! TIRERACK LIES!!!!

what? whats your point here? what i said was that the dealer told me the OEM rotors from VW are 17-18 lbs each. he knew this because VW publishes the weight of each rotor and wheel they sell. he actually read this to me off a book cuz he had to put me on hold to get the book...then come back and look for my specific rotor in the book

the brembo rotors weigh less than stock anyways...so basically you agree with me on your last statement.

and btw, mr genius, i was talkin about rotors, not calipers. you cannot slot and drill calipers. just something you should know the next time you start trolling

hmm. interesting. maybe i'll give ECS a call and see if they can replace my order with slotted only. I knew cross-drilling *could* cause cracking, but i had no clue that your rotors can break into pieces. :Q
Insane, i have a question though, do you auto-cross with your car. or did normal day-to-day driving cause you to go thru 3 sets of pads in few years?

also, how many years?

You ever stop to think that this is probably shipping weight? Including the box etc? There's no way that those weigh as much as heavy wheels.

Yep, they are in fact, wrong. I double checked with a very respected person online, it has been covered before in various places. If you want to argue it at all, take a minute, make a username on team-integra.net and private message MichaelDelaney.

not entirely true

cheap cross drilled rotors are in fact drilled

baller ass "cross drilled" rotors ie porsche/mercedes are formed that way
