So im one of the unfortunate ones that have the 03 models with the defective rotors that warped to hell.
i noticed it started to warp at around 28k on the car, and i still had roughly 50% on the stock pads. i took the car the dealers to try to have them replace the rotors as defective. they said nope, and told me it was fine and gave me the "could not duplicate problem" bull crap when i told them about them squeeking and jolting when applied.

now, only 9k later (currently have 37k on car), the rotors turned to hell and caught me off guard. they ate away the rest of the brake pads, HOLY CRAP!!! and by now my brakes make excessive grinding noise obviously. so i took it to another dealer, they said the front pads are at 0% which they are now, and the rotors are severely damaged and requires replacement. i told them ya damn right i need replacements, because the defective rotors caused the excessive wear on the pads. but they said it was not their responsibility and that the rotors were not defective. they were gonna charge me 480bux + tax and labor to replace the front rotors and pads.

i thot the hell with stock rotors! so i turned them down obviously. who the hell have ever heard of smoking 50% pads in 9k miles?!?! i mean sure i might have a heavy driving habit, but i drove like that the first 28k.

so, i looked around, didn't wanna spend over 250 bux on a new set of rotors + pads.
came across a decent looking set on ebay (none OE) and also offered dimple and slot service. so i thot maybe i'll try em out. so i picked up a set of 4 rotors today, after some basic inspection (well i dont know too much about brakes, but i used common sense i guess?) they appear to be some heavy duty stuff, shouldn't break on me. and i believe that dimples = yes, and cross-drilled = no no, correct? that's y i had them dimpled. im waiting on my new set of brake pads to come before installing.

i ordered a set of EBC Green Stuff pads for the front, i have 65% left on the rear so i didn't bother. i hope this combo will be much better than the stock set up. here's some pictures of one of the rotors i got. what do you guys think?

I like the look of the slotted/simulated drilled, but I'm still a little weary of what they look like when the rotors begin warp from normal use.

I finally ordered new rotors today too. I got the Rotora OEM replacement rotors. I almost went with stock again since I don't want slotted or drilled. On a last second whim, I checked RPM and noticed they had $20 off a complete set of rotors. The cost ended up @ $250 shipped, which is what a set of stock rotors would have cost from a discounted stock parts seller.

I'm at about 38k still on the original rotors, and I kinda get a minor grind on the tail end of a slow stop. I'm also kinda annoyed with how my wheels are starting to get stuck to the rotor due to rust from the rotor. I replaced the pads with Hawk HPS in August and have been pretty happy for the most part. I was also patiently waiting to see if there was going to be a 2006 front brake caliper relocation mount so that I could use possibly use the slightly larger MZ3 (2006 MZ6) rotors, but it was time to replace the rotors.

Not quite. Dimpled is by far less of a problem than cross-drilled. However, you still have some of the same draw backs as a cross drilled rotors. I don't feel like explaining it atm and there should be an article somewhere i'll post it if i can find it.

Edit: duh, the links are in 84fordman's sticky. I wouldn't worry about it too much because these problems/concerns are mainly from a highly abusive driver's standpoint.

I have slotted rotors on my '97 Sable. When I put a lot of pressure on the brakes, say for quick stops they make humming noise. Moderate to light braking they make no noise.

Your new rotors look very nice.

hm... installed them today (fronts only) with bendix pads tempurarily cuz i need to drive the car. so far it makes a little bit of noise im guessing from the slots/dimples cuz it&#39;s not smoothed out at the edges yet and cuz both the rotors and the pads are so new, we&#39;ll see in a few days.

but other then that, braking is great so far, iono how much better if any it is compared to stock rotors and pads since i have had warped rotors for the past few months.

probably gonna get the rear ones installed sometime within the week, we&#39;ll see. but so far no problems

i&#39;ll also get some installed pix, i can&#39;t really see them right now cuz it&#39;s dark outside, i hope they look good too

i love the slotted dimpled look...infact here&#39;s mine...

love the ebc&#39;s very nice feel.

and they will make a buzzing noise for quite awhile, infact mine still do and i have a couple hundred miles on them. i think ebc said something like 1k plus miles it would do that.

the ebc slotted and dimpled. from rpm. i got the green stuff pads up front with hawk hps pads(ebc not avaliable yet) on the rear. and i added the technafit lines, with some valvoline synthetic brake fluid. and the feel of my brakes is just incredible. and i love how it sounds when i slow down, like a airplane...haha.

oh, and i paid 450 for the rotors and pads from rpm. bought the lines for 70 bucks from a fellow 6cluber.
