    Drilled and Slotted brake rotors..?

    Are these a good investment over the stock break rotors? I have never driven a car with them, But I heard they are a good investment if you are someone that likes to upgrade stuff on cars...

    I was looking at these..

    I doubt you'll get 4 good, reliable brake rotors for $119. Maybe apiece.

    One school of thought on drilled, as opposed to dimpled, rotors is that drilled rotors may be subject to cracking under some conditions.

    Go to EBC Brakes and read up on their products.

    If you continually drive under high speed, high heat conditions, slotted/dimpled rotors can provide additional stopping power.

    Re: Drilled and Slotted brake rotors..?

    I had problems with distorting rotors on my 05 DeVille. Yes- I brake aggressively a lot of the time. Over the years on all my vehicles I found that Raybestos rotors and pads seemed to stand up better than all the rest, especially NAPA (although someone told me they supposedly have their stuff mfg'd by Raybestos, I've found them to be sub-par). I put these drilled/slotted rotors on my DeVille, along with Raybestos ceramic pads. BIG difference- no warping, better braking.

    This is what I bought:

    I read that cross drilled rotors can crack too. But some high performance cars come with cross drilled rotors from the factory so there is a little conflict there.

    If you do use slotted and/or vented make sure you choose the pad you want, not settle for, since most places won't turn the rotors the next time new pads are needed.

    Re: Drilled and Slotted brake rotors..?

    I have personally used Brembo, EBC and Power slot rotors. All 3 brands let me down with glazing and warpage but the Power slot lasted the longest and i would advise you avoid cheap castings stick to major brands and quality pads like the Hawk Performance ceramics. You will need around $400 for the rotors and $160 for the pads I personally wouldn't trust no name ebay rotors at that price but thats just me1

    Good luck!

    R1Concepts, slotted and x-drilled w/Axxis Metal Master Semi-Metalic pads, I have 15k on them and there's virtually no wear on the rotors, only some wear on the pads. I've warped ACDelcos and Raybestos in the past, took a chunk out of one ACDelco as well. The R1s seem to be holding up fine, I think I paid around $160 shipped to my door for all 4. Some people have better luck w/cheaper rotors, really you need to get good pads w/whatever rotors you get, that in and of itself makes a huge difference. Warning, these suckers make a lot of noise, they 'chatter' due to the slots, but I have no warpage. cracking, or ineven pad wear due to x-drilled holes that are hardened when they get heated up during the drilling process, overall good product IMHO. Also, x-drilled and slotted really doesn't buy you much for DD, it really only helps you the one day a year I take it to the track...

    According to the brake parts mfr's the drilled/slotted rotors are for looks only.

    At one time it was good for braking because the pads released gasses as they got hot but modern pads do not gas so there is no need to have a passage for the gasses to escape.

    Yes but they do look cool.
    R1 Concept rotors and ACDelco ceramic pads = no problems

    NICE!

    Depending on what the dealer does for my brakes - I may be doing the same thing. I also believe some red caliper paint will look good on a crimson DTS

    Re: Drilled and Slotted brake rotors..?

    Wouldn't a standard rotor provide better stop (although get hotter) because of the decrease in pad contact area caused by drilling? Or would the difference be too small to even tell?

    Re: Drilled and Slotted brake rotors..?

    The difference would be hard to measure except under high speed track-controlled conditions. Any differences noted by the casual driver are usually in the realm of "butt dyno". Slotted or drilled/slotted rotors are, for an urban/suburban passenger car, purely eye candy. Don't get me wrong: they generally look efficient and sporty, and a good caliper paint job completes the look. Just don't think there will be much, if any, difference unless you regularly do panic stops from 85 mph. (Brake rotors are supposed to run HOT, and under track conditions it is very common during a night sports car race to see the front rotors glow red as the car comes to a switchback or chicane. Porsche, Ferrari, or Corvette, those brakes run HOT.)

    Especially with those 20s you need the braking!

    If you want red color calipers, the Bonneville GXP ones are supposedly identical to the Lucerne and/or Park Ave Ultra.
