wat about Zimmermann? I had those on my B5 and I think they're great. but I think Brembo wouldn't be bad at all.

Slotted and cross-drilled barely have any advantage on a stock sized rotor.

Just buy a full faced rotor and use the whole friction surface.

BTW, the slotted and cross-drilled rotors always get caked up with brake dust. Everytime I buy one or the other, I end up wishing I had bought a plain faced rotor.

You can get OEM replacement rotors made by Ate, Brembo and Zimmerman. The funny thing is that they're all the same metal composition so, none of them are better than one another.[rolleyes]

i did notice the holes in the cross drilled getting gunked up but a few shots of water when washing the car cleared it right up.
I did find the brake fade was less prominent and i could get in alot more hard runs without letting it cool

after a track day i had to use a drill bit to push all the pad crap out of my drilled holes. i wish i had taken pics. half the holes were clogged with $$$$ carbotech material.

Has anyone used ATE Powerdiscs on their A4s? I had them on my VR6, and they worked great. Haven't switched on the AUDI yet...

if you like them before my guess is you'll like them again [rolleyes]

#1. I don't find that to be true on either of my two rides... I have the ATE U-Grooves on(no caking).

#2. I find that to be the case (very similar).

I have the Ate Powerdiscs too but, I still get a little caking from time to time. Once my current pads run out, I getting a set of plain faced rotors again.

the whole slotted/drilled/stock argument is played out.

but i would have to say brembo's cross drilled

even if it is just because they come stock on ferraris[:D] [up]

OEM brembo on a ferrari isn't anywhere near the same as brembo oe replacement rotors. Don't be fooled. the OE replacements are good rotors, but cross drilled vs slotted vs plain you won't notice any real difference. The one reason why slots or holes were put into rotors were to address deficiencies in pad materials at the time. Issues related to out-gassing from the padds required a channel for it to escape, as a result slots were introduced. Today slots are primarily used to clean the surface of the pads, and not much more.

I run a brembo GT kit (332mm) with slotted rotors, they don't fill up with brake pad material and have put up with my abuse quite well. I went with ATE rear oe size solid plain rotors and carbotech bobcat pads. If anyone is interested in better braking performance with stock size rotors/calipers, best bet is to get good pads, fluid, and tires. Bigger rotors allow you to avoid brake fade better. Unless you put very wide or very sticky tires on your car, they generally won't provide much gains on the street. OEM brakes have no problems locking up the tires pretty much instantly in emergency situations, the aftermarket setups won't be much different.

the only time I notice minor caking on my slotted/crossdrilled is after a track event... and even then it's minor. Goes away after the next wash or rain.

All I can say is... humidity must come into this. Cause 8 of us here have the same configuration (and I did 7 others cars) and they are A-Okay.
