SLotted rotors? Any good or costhmetic only?

I like to refresh old topics with new info so the server gets less cluttered and the important info is easy to find.
 
1 year old rotors :nonono:

Not unless they were drilled. Then all bets are off. No mfg has a line on non-cracking drilled rotors despite what anyone tells you!
 
makes me glad i have slotted rotors lol

while we are speaking of rotors one of the lebarons we bought off a neighbor had stuck caliper pins on one side and the kid drove it like that for a very long time by the time we got the car the brakes were grinding like crazy the back side of the rotor was worn all the way down to the vented area of the rotor. thats the worst i have ever seen a rotor

sorry that was random and not really related but this just reminded me of it
 
Yes, true. I am sure there are plenty of well made drilled rotors out there that don't do what I posted. I was just referring to the stock replacements for our platform that some people want because they are cool looking:rolleyes:.

Stay with OEM rotors for longevity and safety. These rotors do not feel safe with the condition they are in.

In a pinch, rotors with small cracks in the middle of the face can be used relatively safely until they can get replaced. Once the cracks get anywhere near the edge of the rotor, you are running on borrowed time, and a rotor failure has the potential to be very catastrophic. I've seen race cars where almost the whole corner of the car was torn apart from a rotor falling apart at speed. Granted that's worst case, but if you're having trouble affording a replacement rotor, I don't think you'll be able to fix the massive damage a broken one is capable of causing . . . not to mention injuries, etc. from the inevitable crash.

now that I'm done with my general rant :D, blu, you're right, those rotors are definately not safe to operate at all.
 
If a pizza wedge shape chunked out from the rotor I would be screwed! No way to brake safely with a piece missing from the rotor. The gap would catch on the brake pads, rip them out or lock up completely dragging that wheel.

My brother's front rotors might look like this right now. I will know for sure tonight and will probably change his out right away as well as mine..... :nonono:
 
I'm curious - where did you get those rotors, Joe? Have they got only street use on them, or did you track them at all?
 
Well, if it's any consolation...I'm buying the FSVT front brake kit for my Cougar because my R1 Slotted and Cross-Drilled Rotors have warped beyond belief, haha. Just gathering info on the upgrade.

All street use, I never track or brake hard neither does my brother..... We changed out all rotors that were drilled and all the problems have gone away.

How long have you had them? Just curious, as I have them up front as well. IIRC, I probably have about 15K on them, seems ok so far. Thanks.

Well, my case can't really be applied to anyone. I think I warped them when I got them...I thought you were suppose to go down the road as fast as you can and slam the brakes on. :crazy: I didn't know that would warp an un-broken in rotor...lol. I got the NPG kit today, the FSVT 300mm rotors 3 days ago and now I'm waiting on my EBC Redstuff Pads.
 
From what I have read (many different sources), KyleQ is closest. Under hard use(high heat) as in track days, there will be out-gassing from the pad material. Slots and/or holes will vent this resulting in more effective and cooler brakes.

Just stop, seriously. Outgassing pads haven't been an issue for many years. This was the reason for the origin for drilled rotors, but is no longer terribly relevant, and hasn't been for decades.
