those are brembo plain rotors then xdrill and slotted by some machine shop.

How much were they? Looking at some myself, to replace on front. Want to know if I'm paying fair amount.

well, the ones on ebay are stock sized...aside from that, they are brembo, so what's your point ?

yea i dont trust some guy in his back yard machine shop cutting the rotors......but thats my opponion...asside from the fact sloting and drilling removes surface material (this is what the pad rubs against to stop you)
they may look pretty but only the slots are functional

I bought them over a year ago but I don't abuse them too much, was there not a thread that said brembo does not make a slotted drilled rotor? I remember brembo telling some member that. my stock ones are in real good shape for when my drilled ones crack. I had them cryo treated too so maybe they will last a little longer.

I wanted cross drilled/slotted, but knew to avoid the brembos..So I bought EBC rotors. They are cut all the way through, they just have grooves. They call it "Sport Grooved" and "Cross Pitted". I'm hoping they last a while, because they were pretty expensive.

which way are the vanes/cross drilled direction supposed to go. I've seen it installed differently on manuy cars.

Which way is the proper way?

I don't know if there is a proper way, but the ones in this picture are the "right" way for the rotors in the picture. The rotors are directional because of the vanes (and they are shown in the right direction here), but I don't know if the slots have a preferred direction, or why they might or might not.

Oops, the first time I posted I forgot to mention which way the car moves. The rotor in this picture will be going counter-clockwise when the car is going forward.

I just installed my Brembo slotted this weekend, along with Speedbleeders, Hawk HPS pads, and SS brake lines. If anybody's considering this, give yourself plenty of time! It ended up taking me 12 hours to install it all!!! I'm sure somebody experienced wouldn't take nearly as long, but it was my first time and I was being careful so I wouldn't make any mistakes. As usual, it was the dumbest things that made the job take so long. One of the most annoying things is that the SS lines I got from Mazda Comp wouldn't fit in the bracket correctly on the back rotors (fitting was a hair too big). So a little dremelling was a necessity. Another frustration was that the pads wouldn't go in the rear brake calipers. The little metal plate that goes on each pad was the difference, so I had to leave one out. Anyone know what they're for? Figure as soon as I wear the pad down a tad I can put them back in.

So far, I like the Brembos, though. They have a silver coating, which is interesting because it scrapes off where the pad rubs, which leaves the silver in the slots. I love their subtle but purposeful look. I'll be taking them to the track next weekend and putting them to the test.

Just figured I'd share my experiences, for what it's worth....

yeah, I was just replacing the rotors and pads. it took me quite a while on my car as well. though I had to have my rears rebuilt. The piston boot on one of the rears had ripped.. The rebuild was the most time consuming and expensive. Then you do stupid stuff like forget the spacer washer on the front bottom caliper bolt, and have to figure out how to break off the stock rotors from the hub.

I used a Motive Products Powerbleeder. It seemed to work well, but I don't think I userd it correctly, because I ended up with a lot of air in my lines, and at that point I was too frustrated and had a race the next day, so I just took it to a brake shop to have them bleed it.

TailHappy

Yup, sounds like some of the same stuff I went though. I didn't have too much trouble getting the old rotors off...block of wood and whacking the hell out of them with a hammer....probably the most fun part since it let me get rid of some frustration right about when I was needing it!

I'm sure it sounds like a broken record at this point, but I went the Speedbleeder route after hearing so many good things about them. Cost something like $40 including shipping for the 4 brakes and the clutch. They make bleeding a real no-brainer. In fact I think it would be impossible to not do it correctly with them (so long as you remember to keep the reservoir full). They get my seal of approval....

the rotors actually come off without hitting it with a hammer. :P

There is a little threaded hole in the rotor. Not one of the holes for the screws that hold it on, but another smaller hole. You find a bolt that will fit in there, and turn it in. The rotor just pops right off..

Hammer time! Postwhore strikes again! Mwahahaha!
