What are better rotors?

[Skorch]

Cross drilled, Slotted, Crossdrilled and slotted..:think::dunno::help:

What are you going to use them for? That's how to determine whether you get something that will work under race situations or just normal city driving and you want to look pretty.

Well, they'll be for everyday driving. I tend to get on my car alot though so I want something made for performance aswell.

I heard one of those types of rotors wont warp as easily too, but I dunno that much about brakes...

Is it best to get 4 new rotors when you replace? What about calipers...should you replace them aswell?:help:

Mine are warped at the moment. I know I can get them turned or whatever, but I think I would rather just pay some extra and get something that will last. I figure I'll save in the long run.

By get on my car? Are you autocrossing or road racing? If not, get whatever you like. Sloted, Drilled, slotted and drilled make them as pretty as you want. If you race, get blanks and agressive pads. I have slotted with OEM pads and next time I'll get slotted and drilled with OEM pads.

Road racing for the most part. It's not something I do alot though.

What are the advantages of slotted and drilled as opposed to just slotted?

[eboggs_jkvl]

Um... Road Racing is literally what it means. Not doing a red-light sprint with another car as in street racing. Road Racing needs blanks and really grabby pads. Occasional street racing can take the pretty rotors. The slots and drills used to be functional but now, they are decoration and simply your choice of what you like.

haha, Road racing , Street racing...:o So are you just gonna buy them for looks?
I thought they actually did something... I thought it helped in keeping the rotors cool... Do you generally get new calipers or just keep the ones you have?

[eboggs_jkvl]

As I said, the slots and holes used to be functional but not really a decision factor now. If you "race" you use blanks. If you drive on the street, you can use what you like.

I reused the calipers the last time I changed. I plan on a brake upgrade soon and I'll get much larger rotors and big 4 piston calipers. Were I "racing", I'd get the 6 piston ones for the front, but I'm not :racing".

Thanks for the info:)

What brand would you consider going with if you were me? I noticed most of our sponsers carry Baer. Kinda pricey, I want to buy something that has great quality especially with it being brakes. Wasn't really expecting to pay $800 for a brake job though. What do you think? Guess I'll be going with the look factor aswell...:D

[eboggs_jkvl]

Well, I have the powerslots and they seem to be functioning well. Baer or Wilwood will be my next choice but I'm doing that purely for show and to fill in my 19" wheels.

I have Power Slot Rotors, Hawk pads,Earl's Hyperfirm brake lines. I like them. I saw some slotted rotors on some NASCAR cars. So that's why I got them. When I put them on, the braking was much firmer. I like my brakes now. Got all this in one kit from Thunder Racing.

The function of drilled rotors is to allow a path for the gases generated by the pads to escape from under the pad. It also allows some air to flow through the rotor for cooling, but this is better achieved with directional vane rotors. A couple of downsides with cross drilled rotors are they can crack around the holes if they are not drilled properly or weaken the rotor if not located properly.

Slotted rotors also provide a channel for gases to escape from between the rotor surface and pad. They have the added benefit of keeping the pad material fresh by wiping the pad surface. The downside is increased pad wear.

With the new pad materials, gas generation is no longer as big an issue as it used to be, which is why blank rotors will work well.

If you are road racing the car, I would tend to go with slotted rotors. Personally, I would be leary about cross drilled rotors due to the potential for cracks.

You will note that some high end street cars and race cars use cross drilled rotors.....so they must be better. That may be true, but then these rotors are considered to be a dispoable consumable wear item......like the pads. Meaning they get replaced on a frequent basis. So if you don't mind spending the bucks for rotors on a frequent recurring basis, then cross drilled rotors would be an option.
