Slotted, Cross-Drilled, blank or Both?

Slotted, Cross-Drilled, blank or Both?

Which one do you guys think is the best type of brake rotor out there?

IMO
1.) I think cross-drills are mostly for show, because break dust gets inside
the rotor, which can't be good for the braking system.

2.) Blank Rotors do not have any way to clear out break dust.

3.) Slotted, the best because it clears out brake dust without getting into the
rotor and is F1's unanimous choice for rotor type.

Either blanks or slotted or cross drilled. The combo is for show IMO

For the street, blank rotors with good pads work just as well if not better than drilled and/or slotted rotors. The only reason drilled/slotted is necessary is for dissipating massive amounts of heat. I doubt any street driver would lay on the brakes that often or brake from very high speeds all the time.

OEM Rotors are the best! I don't think I know anyone on this forum who even needs slotted or drilled rotors anyway.

Don't you race drunksaru? Are you saying that even on your track days you still don't need slotted or drilled?

I think you just posted somewhere else that your EBC pads were constantly getting glazed over, don't you think that if you had slotted rotors that wouldn't be a problem, because the slots constantly remove glaze from brake pads?

Just curious.

The problem with many drilled rotors is that they are blank when they're made, and drilled out later. This weakens them. The only good drilled rotors are the ones that have the holes machined into them when they're made.

There's no real need for drilled or slotted unless you're going to be on the brake all the time and/or stopping from high speeds a lot. Drill/slotted is to prevent brake fade where the brakes fail from being too hot. Even in autocross, no one is on the brakes long even to get that bad of fade. That's why I agree with DrunkSaru. All you need is better pads and stickier tires if you want a shorter stopping distance. btw, having drilled and/or slotted rotors reduces the life of the rotor since you have less surface area and the same amount of pad contacting it. If you're in F1, then I understand. Even if you're a speed demon who like to go in excess of 120+ mph on the freeway, I understand, but for normal cars with occasional race days or spirited driving... not really.

slots are not just about cooling down the rotor. They have other purposes like evacuating gases released during braking and scraping dust off the pad surface.

I had cross drilled and slotted on the Corolla and that was overkill, mainly looks.

I have slotted on the Civic with Ceramic Pads and its better than the stock and blanks I had on the car, but I drive a lot.

In that case, slotted would be the better of the two.

i got wilwood cross drilled and slotted with 4 piston caliper and true thy look bad ass but when i`m chasing down a vette or viper and the best , running agains a fd,fc,s13 or s14 with someone that think thy can Drift , thy do the job when i brake in the corners.

That was my original question

There you go. Jump on Goku's deal.

I have elliptical slotted rotors, and despise cross-drilled.

I don't race. I used to go to track days for fun though. I can't afford it anymore. But for most people who go to track days once in a while where you're going around the track about 5-6 times before you have to get off and let others on, drilled or slotted rotors aren't very necessary. You'll have better performance if you just upgrade the size of your rotors, upgrade the caliper, and get nice brake pads. My friend with an 05 Subaru has 14inch rotors, 4 piston calipers and some nice agency power steel braided brake lines and OMG, that thing stops so quick make you feel throwing up your lungs.

If you want to get slotted or drilled rotors, I would go with slotted. Drilled can go bad (crack) very easily unless you get it from a trusted well known company. Even slotted rotors, if you aren't careful, can warp easier than OEM. I personally don't find it necessary unless you are actually racing and you're doing like a 20 lap race or something. If you just want to go for looks, I guess it really doesn't matter but when I was on the track, I used to floor the brakes giving myself hella negative G before going into corners. Thats kinda how I was taught. which I can't do anymore.. I don't have the guts. haha. Also learned how to properly heel-toe too

I used to be heavily in the amateur race industry so I've picked up a few things here and there but that and me going to track days once a year is about the extent of my "racing" knowledge. Oh but it was good enough knowledge to where I almost got interviewed by some lady who wanted to know what drifters wore clothing wise back when Fast and furious 3 was in the making.

Interesting, interesting.

Personal Preference... Slotted or Dimpled... Dimpled creates little air pockets that's suppose to stimulate the same purpose as the slotted. Drilled, I agree- has a *higher* tendency to crack as cgreen38 said, unless it was forged with the holes, drilling into the metal afterwards weakens the structural integrity of the rotor. Or... you can get Slotted Dimpled!
