i can't find anything anywhere for them, all the rotors i find will fit the SS/SC, but they say they don't fit the turbo model, anyone know if they have anything out yet, because i want to get them, if anyone know where i can them send me links please and thank you

bumpage

 

nothing that we know of yet, all the mfgs say "in process" no eta

I will keep you guys updated though, i'll shoot off a couple emails tomorrow

 

thx alot man

 

i just want slotted i dont need drilled.

Genuinesaab.com sells some slitted stock ones. Not drilled though.

 

many would argue that the drilling process makes brakes worse and does not provide a benefit. any takes on this?

 

I've heard the same. I'm not sure myself. I mean many very high end supercars / hypercars use them. I know drilled ones tend to crack so if it were ME, I'd settle for slotted.
I've heard argued that there is less metal for the rotor to act as a heat sink. Also vented rotors are what makes all the difference. The vanes in the middle. Some are directional, some are not. You have veins that go all the way through and short ones.
Also, many people get something else wrong. Those vanes are more important than people think. A slotted rotor can go on either way. Slots facing backward \\\\ ---> front of vehicle. Or forwards i.e. the way most people do NOT put them on. However, in almost all cases if they are vented rotors (the vanes in the middle are directional) the SLOTS actually go on facing the front of the vehicle. //// ---> front of vehicle. I was given a warning sheet when I bought slotted rotors for my last car.
I did notice improved fade resistance on that car. HOWEVER, the brakes were not all that great from the factory, unlike the SS/TC's. Then I put on racing pads and that was too much heat for the rotors. So I went slotted. For example, doing a hard stop from say... 100. Even with racing pads and slotted rotors the brakes were literally smoking on that car. I've done similar in the SS/TC with stock brakes and it "didn't break a sweat" so to speak. Didn't even phase it.

I'm not convinced it's really needed on the SS/TC. I think it would be for looks myself. Just my opinion.

 

Pads and rotors would be nice!

 

I have heard good and bad about drilled rotors. Super cars use them, Z06 and ZR1 use them. I think then are ok as long as they are from Brembo or good brand name. Ebay cheepos don't work, buddy put them on his R32 and they cracked in two weeks of use. Power slot cryo work well.

cheers

 

I stumbled across this a while back (http://reviews.ebay.com/Drilled-vs-s...00000005243690)... an interesting read about a test of dimpled/drilled and slotted rotors by some GM engineers.


Yeah, the slot direction doesn't matter, just the louver vents between the two rotors need to sweep forward as seen from the top if it's vented. If the louver vents have a no sweep angle then you can mount it any direction you wish.

Personally, I'm like you and like the "\\\ --> Front" sweep angle on the slots myself too.

I wonder if Genuinesaab.com would dimple them for me too.... My friend's got some slotted+dimpled rotors on his SVT Focus and I must say they look pretty hott.

 

X2 I like the drilled and slotted rotors to face front like that.

slot direction does matter. do not get any drilled rotors.

 

hmmm well are the rotors from the ss/sc the same size??
if so cant we just buy those??
but idk

 

Wrong, not always. This is a DIRECT copy/paste from Brembo's website.

"Which direction should the discs rotate?
It is a popular misconception that the slots or drillings in a disc determine the direction of rotation. In truth, for an internally vented disc, the geometry of the vanes dictates the direction of rotation. There are three vane types in use:

Straight
Pillar vane (comprised of many small posts)
Curved vane
The first two vane types are non-directional, and can be used on either side of the vehicle. The curved vane disc, however, is directional. A curved vane disc must be installed with the vanes running back from the inside to outside diameters in the direction of rotation. Please see figure. Orienting the disc in the manner creates a centrifugal pump. The rotation of the disc causes air to be pumped from the center of the disc, through the vanes, and out through the outside diameter of the disc. This greatly enhances the disc's ability to dissipate heat.

Additionally, all of Brembo's slotted discs are directional as well, regardless of the vane geometry. The discs should be installed such that the end of the slot nearest the outer edge of the disc contacts the pad first."

Even in the case where the slot direction DOES matter, (apparantely Brembo slot direction matters) it's like this //// ---> front of vehicle. Outside edge contacting the pad first. (Manufactureres may vary) Either way, it clearly states that it's the INTERNAL VANES that dictate which direction they should rotate.
You can't always just choose which way you want them or which way YOU think is best. Anyone who buys rotors should read the installation instructions to be sure they are on the correct way. I'm sure there are thousands of rotors out there installed incorrectly because it seems to be a simple and straightforward procedure. With many of these high performance rotors, there is a correct and incorrect way.

 

congrats on contradicting yourself.

 

How do you figure? If I did, then Brembo did as well.

"It is a popular misconception that the slots or drillings in a disc determine the direction of rotation." - "Additionally, all of Brembo's slotted discs are directional as well, regardless of the vane geometry.". That's from Brembo. So if there's a contradiction, there it is. Ask them. It doesn't state why their slots matter. It does say however "All of Brembo's slotted discs"... not all slotted discs.

I stand by what I said, internal vanes (when curved) will ALWAYS dictate rotational direction, not the slots. Just because you're a good tuner doesn't mean you know everything.

This is from Stoptech (the brand I purchased for my last car) - direct copy/paste
"The slots on StopTech AeroRotors are cut in the OPPOSITE direction of the vanes. The pattern on a drilled AeroRotor also has the same appearance. The direction of the slots or hole pattern should not be used to determine what side of the vehicle to place a rotor. Different manufacturers may have different strategies for slot and hole patterns.

The only correct way to determine what side a directional rotor goes on is the internal vane direction." <---- did you get this? Are you going to argue with the manufacturers now?

Shall I go on? I can grab as much proof as you need. I know what I'm talking about.

This is from Wilwood Brakes explaining why slotted/cross drilled rotors are generally unnecessary. Again, direct copy/paste.

"Slots or grooves in rotor faces are partly a carryover from the days of asbestos pads. Asbestos and other organic pads were prone to "glazing" and the slots tended to help "scrape or de-glaze" them. . Also, cross-drilling and/or slotting the rotor for racing purposes was beneficial by providing a way to expel the gasses created when the bonding agents employed to manufacture the pads began to break down at extreme temperatures. This condition is often referred to as "outgassing.” When it does occur, the driver still has a good firm brake pedal, but a significant reduction in friction. Normally this only happens at temperatures witnessed in racing. However, with today’s race pad technology, “outgassing” is no longer a concern with pads designed for racing."

 

Most of the time the cracking is due to the hole being to close to the outer edge of the rotor.

 

Or the rotor being too thin or made of inferior material like the first set of front rotors on my car that warped after 800 miles.

What is wrong with well made drilled rotors? They vent off the hot gasses better and run cooler both of which help stopping ability. If The ZR1 Vette has them I would say they do provide a benefit.

 

drilled rotors do not aid in increasing stopping power.

 

That is not what the test report I read said. I dont know I have no experience with drilled rotors but if they make no difference why do all the supercars have them?

 

Where I see them benefiting is from VERY high speed. You know like when they design a car that can go 200mph. As Top Gear said, it has to be fitted with everything else to support that speed. 200 mph suspension, 200 mph body, 200 mph brakes.
On a race track where say the speed never goes beyond 120-130 on the straights or something they may not be needed.

This is just my opinion now.. so no one get all defensive please.
I think if the actual air (not gases generated by the pads) heats up so fast it may not escape the internal vanes fast enough. Building pressure and heat inside. So then the holes give it another means of escape. This of course being a hard stop from high in triple digit speeds. So what I'm saying is I'm not sure if they are really effective with several "lower" speed stops because of the brief cooling time between. If that makes sense.

That's just my opinion though... If they were effective on the lower half of triple digit speeds I'd have thought they would have fitted the SS/TC with them.
