I was looking over the different rotors, there are a wide combinatio of them:
DRILL/SLOT
SLOT ONLY
DRILL ONLY
DIMPLE & SLOT
BORE & SLOT

Is there any difference between them, or is just a choice of style?
Thanks

Drill/Slot is overkill and removes to much surface material. There for looks only.

Slotted prevents pad fade by allowing the gasses to escape from under the pad during extream braking temps.

Drilled allows the rotor to cool a bit easier allowing for better resistance against brake fade.

A solid rotor has the most surface area, hance the most friction you can get from your pads. They will offer the best stopping power under normal braking conditions.

For street use, the regular are the way to go. Even if you really drive hard.

if drilled/slotted etc are for cooling purposes...but don't provide maximum grip...why do BBKs come with drilled/slotted and bite wonderfully?

This will answer all your questions and should be a sticky.

The rotor and brake caliper are bigger then the stock units. So of course they will brake harder just by the size differance of the system your replacing.

You need to compair apples to apples, not apples to grapes.

coupla links i'd just posted in another thread discussing it earlier on a different forum. i think for pretty much anybody's street car - even for track use - the rotors don't really do much either way. most modern pads don't even gas off in a way where slotted would help, except for some track ones where you need to heat them up to ungodly high temps for normal operation. it's much more about the pads and having good lines + fluid for good braking performance.

my friend's max has had slotted brembo rotors on it for a while now, and AFAIK he's planning on switching back to solid rotors when he next replaces pads.

that thread mentions the actual rotors....what about the high perfornace pads?i remeber i used my axxis metal master pads with oem rotors and they ATE through them. and i have used oem pads with x drilled and slotted rotors and they turned to dust. i think if used in conjuction with the right equipment it works efficiently. i dont think mercedes and all the sports car companys putting x drilled and slotted rotors or whatever combo of non blank rotor is stupid. they do offer better brake performance if used with the right setup. i also dont think millions of people would be part of a giant scheme by brake companies and everyone would have the placebo affect from it. i feel as if my brakes are a hell of alot better i went from a full OEM setup to x drilled rotors axxis metal master brake pads and SS brake lines. so it was like night and day. just my 2 cents

i do think tons of people have a placebo effect from it - especially with just as many people telling you it doesn't make a difference, with most of the naysayers being vendors selling those rotors and/or people that track their cars regularly.

benz. and co will do it whenever they can because their customers expect that sort of bling out of a $120k german car. come on, can you imagine an amg with 19" alloy wheels and not seeing monster cross-drilled rotors underneath? porsche's and the like might be more practical, i don't know... same deal though, not many will always do what's best for the performance vs. what their customers want out of a car.

well mercedes and porche arent a bunch of idiots and with mercedes having one of the fastest cars and running in formula races and what not i dont think that their tech isnt up to spec. i dunoo tho i felt a difference but i went from stock which was basically metal on metal to brand new everything so it was a world of difference to me.

Don't forget about multi-piece rotors such as these:

lol.

Such as 6-piston calipers? On a street car? Why not. You just spent $2,000 on rotors. Might as well go all the way. Oh wait, the fronts have 8-pistons. Never mind.

Keep in mind that the rotors I linked to have nothing in common with the one-piece rotors you've been looking at.

If it is available online, Nopi Street Performance Compact had a great article on all things braking in their Oct/Nov 2004 issue.

Just stay away from racing fluid. RBF 600 Racing fluid for eaxmple has a super high boiling point but isn't "perfectly neutral with seals used in braking systems." Also, it needs to be changed more often because it draws more water from humidity than the standard DOT3 recommended in your Maxima manual. It can damage the seals in your calipers or your can experience fluid failure if you aren't prepared to change your fluid fairly often. It's a bit scary when your brake pedal unexpectedly drops all the way to the floor.

Brembo blanks are cheap. Another advantage to blanks is less brake dust. The stock Akebono calipers are actually very good. I use Hawk HPS pads. I get better performance out of them than the OEM pads (which are not bad, just not designed for lots of frequent and heavy braking).

If you drive hard drilled slotted are the way to go keep your brakes cooler

But if you are going for looks, cross drilled rotors would looks bad@$$ if you have rims exposing them.

I run brembo slotted with ebc green stuffs on the front and hawks on the rear. I must say when I upgraded I did notice that brake fade is pretty much eliminated. On a hard stop from 60 to 0 when they heat up you also hear the slots humming. I needed new brakes so I decided to upgrade to slotted, In my opinon it was a good choice.
