Took a few pics...
My luck though; its POURING rain out and I can even go test them out

overkill

Looks good

And are they just the rears?

that looks sick, i'm jealous.

I was thinking BIG BRAKE up garde . good to go with SLOT. never buy Cross drill it will crack no mater what is the brand of rotor

plan9

Nope, front and back.
And to address the previous posted: my mechanic friend purchased and installed them for me, I believe they are just stock size and I think It was 550 or 600 for the whole set, with pads, and another 100 for the steel braided brake lines.

Yeah I was thinking he meant the Brembo Big Brake Kit. Has anyone ever installed that? The Brembo catalog says it's available but I've never seen it on an FD.

been using x-drilled for about 6 years, never had a problem

Cross drilled do not have any problems cracking. I've only heard other people repeat the rumor and no one that I know has had it happen to them. I have had them on my CRX since '92 and had them on my GSXR. In fact, don't all crotch rockets have them?

BlueRex

Looks nice, and hopefully they will have some great stopping power too. Don't forget to follow the proper break in period, wouldn't want to ruin those nice brakes.

I've only heard of crossdrilled rotors cracking in rare cases such as repeated, hard track driving and I think that problem was solved by the introduction of dimpled rotors.

How do you break in new brakes? Im thinking about getting new rotors and calipers on my car and was wondering.

BlueRex

Most of the time they'll include a little instruction on installation and break in. If I remember correctly from my brake install on my integra (it's been a while so this may not be correct) they said to do 10 slow easy stops and then one hard stop. They also said to go easy on the brakes for about 200 miles I think. Like I said it's been a while so don't hold me to those instructions.

most "crotch rockets" do have cross drilled rotors but their rotor faces present a larger surface are with less volume and htus better cooling ability not to mention they are stopping much less mass althought i can not back this up with any data it is my assumption. i dont think cross drilling presents any "clear and present danger" except for track drivers or brake riders. btw. awesome rotors. they are now officially on my evergrowing "to do" list

Those rotors look really good Plan 9.

By the way, there are cross drilled rotors on the new BMW M-5.

John Magnuson

Most aftermaket cross drilled rotors have the holes drilled into them after they are cast. This is less than optimal and often results in cracked rotors if used heavily, like at a track. I've seen it myself many times. If the holes are cast into the rotor to begin with, like on Porsche cars and other high end sports cars, usually you won't have any cracking problems.

Ive had cross drilled and slotted rotors on my car, daily driven and I drive it hard...never cracked and still brakes great..after being turned a few times..

spoolin93r1

ALL rotors except for ceramic or carbon ones are drilled after the casting process. this is another old wive's tail that the internet has spread so nicely. i've talked to reps at brembo about it before

John Magnuson

Good to know. I was told about the casting by a porsche mechanic not from some internet site. But he could have been misinformed. I'll check into it.

You can get front & rear rotors, pads and lines for $455.00 shipped

Porsche are the only company who cast the cross drill hole in their rotors.
and all other company they mill the hole after rotor been cast. you can tell the way of porsche cross hole is a bit different than all other company
here is the link I found
http://www.movit.de/rahmen/frontbks.htm
this company use only porsche brake calipers and rotors.

[quote]think rotors: made of special steel alloy, MOV' IT ® rotors are all vented with cast not drilled holes. that means no tension, no cracking, no splash shield required, and the perfect ventilation for optimum braking. special slots make the surface area of the ventilation system much larger than in conventional rotors, keeping tem-peratures down and durability up[quote]

YES If you daily drive your car and never take it too mountain or track day. the cross drill will never crack. I took my RX7 to track all the time, and from my experience this happend all the time,

Stock size rotor are never mean to be cross drill. they are too small and too thin meaning you are take too much material away. and repeat of heat cycle will crack those hole very easy.

Comptech

Dont you have to break them in first? I just put a new set of Brembos on my car and they came with this long *** instrcutions on how to break them in. Maybe mine are different.

To echo what diyman25 said, cross-drilled rotors are fine for the street, but I would not recommend them if you plan do to any serious tracking of your car. They will crack under that kind of extreme use.

As for breaking in new rotors, I think you do have to do some seating, more to fit the new pads to the surface than anything else. I think you need to do a few HARD stops from a good amount of speed, the park the car and let them cool, but it's been a while since i read up on that procedure so if anyone knows better please correct me if I'm wrong.

radkins

I had brembo drilled rotors on my car and they cracked bad. If you are light on the brakes they may be OK but if you drive it agressively they wil crack, no doubt. My frien put them on his supra and they lasted two track sessions before cracks appeared.
