Suspension, Brakes and Tires Discussion, Drilled and Slotted brake rotors..? in Item Specific Cadillac Discussion; Are these a good investment over the stock break rotors? I have never driven a car with them, But I ...
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.
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
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...

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.)
