sloted and cross drilled brembro

[my240likenoother]

the seller was Elvis
if you had the winneng bid on the 5 that he had have you recived them yet???

[vancouvers14]

i was gonna buy from him privately, but i didn't like his answers....
hope you get em

[s14vaxlr8]

yeah i got them too, the money was taken out through paypal, i havent heard nething on shipping though...but he did leave feedback for me, but ive emailed him like 10 times, no response

did you bid on them through e-bay
have you recived them??

if i dont get these brakes i will (as i toss the keyboard and snap it over my knee <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/mad.gif" border="0" valign="absmiddle" alt=':angry:'>

[s14vaxlr8]

yeah i bought them through ebay...i spoke with one of the other bidders, and he said that the guy elvis sent them out and gave him a tracking number, i hope we arent gonna take it up the ass on this one..

cody

[vancouvers14]

nope, i didnt bid on em. &nbsp;decided to spend the extra $80 and got them at a local shop

[s14vaxlr8]

were they slotted and drilled...bc i heard that brembo only makes slotted, then again, im probably wrong..

another question, i have 300zx na calipers, will they work with the brembo rotors, if not, ill be sellin, they were free anyways

[MorganS13]

they're probably slotted and drilled...i got a set of 4 off ebay durin the summer and i love them so far. &nbsp;i like the sound they make when u get on them hard. &nbsp;now i need to replace my rear drivers caliper thats seized so i can put the rear set on too...

brake standes i assume???

[MorganS13]

u mean brake stands i assume? &nbsp;its not really loud but if i have my windows down and i'm braking much harder than normal (i wouldn't say standin on them cause i never really brake that hard), i can hear them due to the slots (obviously). &nbsp;it might just be me listening too carefully also, i dunno. &nbsp;maybe someone esle with slotted rotors can add somethin so i don't sound crazy. :-)

[my240likenoother]

well here is a pic of them
i got one of them painted so you could see what i was talking about

Brembo doesnt SLOT or DRILL any of their rotors. &nbsp;However, their BIG-BRAKE ROTORS (which are sold and only work with their big brake caliper upgrades) are *cast* with the holes in them.

The stuff you guys see on e-bay is just aftermarket handy-work. &nbsp;People with a drill press just drilling and slotting you a rotor..

The slotted ones are fine. &nbsp;The drilled ones have less mass and are prone to cracking. &nbsp;Hey, atleast they look pretty.

[my240likenoother]

you migh wanna check you info on that
on the side of the disk it says brembo andyou can tell that it has been cast and its not someone with a drill press
if they r pron to cracking how come i have never heard of this??
if they crack that may be from abuse some people think that they make you stop faster so they go out and wail on the brakes causing them to heat &nbsp;up hotter than they r made for these r not made for auto-x regular street driven

[vancouvers14]

old s13 is right. &nbsp;brembo makes blanks. &nbsp;thats why it says brembo on the side. &nbsp;aftermarket retailers drill the holes and the slots.

the only brembos that come that way cost over 2K, and you didnt buy those for 200

[my240likenoother]

ok well who ever drile thos holes and slotted them i give much props

say brotha, give props to the person (or machine) that drilled your rotors all you want.. the truth of the matter is, you paid for a rotor that cant handle the heat!

hehe its all good yo, thats why you have white flames going down the side of your car.. to show the power, not so much to produce it! &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> hehe its all love though, i'm just playin.

next time, do some research before you buy. &nbsp;you'll quickly learn how SO much of the shit being sold ISNT as good as the factory. &nbsp;less mass = less stopping power. &nbsp;true, the holes DO allow the rotors to cool off quicker.. but then again, I dont think you'll ever have to worry..

less mass less stoping power.....where did you hear this. &nbsp;more mass is just more inertia making it more difficult to stop the brake from spinning. &nbsp;obviously theyre not prone to crack because all the best automotive manufactures use drilled rotors in theyre cars. &nbsp;mercedes, ferrari, lamborghini. &nbsp;unless you have drilled rotors and they cracked i wouldnt accuse them of doing so.

minime&gt; &nbsp;Lets see if you can follow this train of thought:

bigger rotors = more surface area
more surface area = more mass
more mass = better braking performance
better braking performance = BIG BRAKE UPGRADE

now, lets look at the second picture:

drilling a SOLID rotor = less mass
less mass = less surface area
less surface area = less braking performance

NOW. &nbsp;When you look at a true-exotic car, the rotors are not DRILLED, they are cast WITH the holes in them. &nbsp;See, everytime you DRILL a rotor, you reduce the rotors strength. &nbsp;Even though the rotor will run cooler, its prone to cracking - PERIOD. &nbsp;This isnt the case with big-brake Brembo/Baer/Etc upgrades, because they are CAST and tempered.

Me? &nbsp;I've worked on plenty of brake jobs to know. &nbsp;I've tossed out a very fair share of cross-drilled rotors, I dont need to OWN them to understand.. I've worked on them. &nbsp;SO, unless you shell out for an exotic big brake upgrade, you've got a rotor that doesnt perform as well as a solid or slotted rotor.

Easy boys...

I have heard of cross drilled rotors cracking, but like My240 said, it isn't going to happen unless you are REALLY riding on the brakes. &nbsp;
Old 13 I'm with you most of the way. &nbsp;Cast with the holes in them is better than drilling the holes after the fact, but it isn't like they instantly turn to crap. &nbsp;If they're drilled right it isn't all that bad.
Repeated moderate braking for a long time (like on a track) generates alot of heat so cross drilled (or pre cast holes) do help. &nbsp;The only way you're going to crack a rotor is by stomping in the brake. &nbsp; And a quality brembo rotor is going to be less likely to crack than a cheaper rotor.
Also, shouldn't it be: &nbsp;
bigger rotors = more surface area = better braking
The mass doesn't really slow you down faster, its more the surface area, and pressure applied.
Slotted and/or cross drilled rotors do help braking performance if done correctly. &nbsp;They do slightly reduce the structural integrity, but its a trade off, just like anything else.

archangel&gt; &nbsp;I can agree with that. &nbsp;However, if you're going to have a rotor drilled.. all most places do is chamfer &gt;sp&lt; them.. that way the hole doesnt crack as easily. &nbsp;Plus, most places are using really small holes.. not too beneficial if you ask me.. but its all good.

I drive harder than most people and I only use cryo-treated Brembo rotors that I have slotted. &nbsp;They are pretty #### durable. &nbsp;I have other friends though who've had Brembo's drilled.. and they dont drive nearly as hard as I do. &nbsp;I've still seen the cracks. &nbsp;Eventually, they do develop.. it just takes time.

Personally, I just want a super strong rotor. &nbsp;Can you cryo-treat a cross-drilled rotor? &nbsp;Sure. &nbsp;I think that would help. &nbsp;BUT, you still have less mass, which is the same thing as having a smaller rotor. &nbsp;That is why most people tend to run slots on their cars.

inertia is the enemy of braking. &nbsp;braking doesnt have anything to do with mass. &nbsp;its jus the surface area and pressure aplied like archangel. &nbsp;if you drill holes you loose some surface area sure but that is compromised by the fact that you can brake harder because the brake will cool down faster. &nbsp;more mass isnt better. &nbsp;try spining a frizzby and slowing it down then get a 10lb weight for the bench press and spin that and then try to stop it.... its gonna take longer for the heavier one. its simple physics

i we all seem to understand the basic concept. &nbsp;unfortunately, I still think mass plays an important role. &nbsp;try braking with some aluminum of an equal surface area and see how good your performance is going to be. &nbsp;If you dont like the word mass, then we can stick on using surface area. &nbsp;BUT, nonetheless, a cross-drilled rotor DOES have less mass.. therefor, it DOES have less braking potential than a solid rotor of equal circumference.

BUT, if Brembo uses them, why? &nbsp;Thats because they design the size of the rotor WITH holes to exceed that of a normal rotor. &nbsp;When you have a 13&quot; disc full of holes, it doesnt matter if its true mass (or surface area) is the same as that of a 11&quot; rotor.. because its already oversized.

But take an 11&quot; Z rotor and drill it full of holes, then you are left with a rotor the size of a stock integra rotor. &nbsp;Fun.

[Tuck&Poke]

ok look answer this. &nbsp;other than the obvious fact that carbon fiber can sustain tempetures of excess of 6,000deg farenhiet why the crap do you think they use them in racing? cough cough less mass cough! &nbsp;fine i agree with the surface area its true more surface area stonger braking but i just cant agree with you on the mass thing.

aluminum is a totaly different metal &nbsp;so yes that would be very different

[Tuck&Poke]

yea homie aluminum cant take the heat

[zephyr]

uhm...technically drilling gives you ::more:: surface area, but less ::braking:: surface area
just thought id be an ass and say that

[Nismos14]

how does drilling give u more surface area? LoL

[sykikchimp]

Mass is NOT the same thing as surface area.. &nbsp;Two completely different things.. &nbsp;That do completeely different things when speaking about brakes. &nbsp;I did quite a bit of research on brake rotors a while back, and found that cross drilled rotors are more Ideal for daily driven cars, with high heat braking situations, such as Vans, and Ambulances, etc. Because the extra load would heat them very quickly and where down solid rotors faster. &nbsp;Slotted rotors on the other hand will actuall cause MORE heat on to be generated. &nbsp;The basic Idea behind the slotted rotor was to keep the Brake pad clean of imperfections, thus increasing the surface area of the brake pad. &nbsp;Reducing the life of the pad. &nbsp;For their Purpose, Extreme braking in a race situation, they do wonderful. &nbsp;Another draw back of slotted rotors is more heat is generated as well. &nbsp;Because in a race situation, you want hot rotors. &nbsp;Performance is increased. &nbsp;I'm not saying braking 100-0 10 times in a row hot, but hotter than normal. &nbsp;Also decreasing the life of the Rotor. &nbsp;

Of Course these were their purposes. &nbsp;What your specific braking needs are are the true deciding factor in which you should chose. &nbsp;Slotted rotors are hotter than normal rotors, therefore they don't last as long as normal ones. &nbsp;Cross drilled rotors should (technically) last longer than normal rotors, and provide better stopping power in specific situations. &nbsp;But like you have already pointed out, in normal situations, normal rotors will shine. (normal being driving through town in your 240sx) cast holes, or not cast holes, and cryo-treating all play factors in a rotors lifespan.
I choose the Slotted and Cross-drilled rotors hoping to get the best of both worlds. &nbsp;The good contact patch of the brake pad from the slots, and the cooling affect of the Holes. &nbsp;They sorta Counter-Act each others Negatives. &nbsp;
I can say from experience that the rotors I had, be them made by Brembo or not, Where WAY better than any OEM rotor that ever came on the 240. &nbsp;NO more brake fade. &nbsp;Gone. &nbsp;Better wet braking performace, and I could brake harder without locking the brakes.

Sorry for the book.. &nbsp;And It's been a while since I did that research.. like a year or so.. I'm going of my memory. &nbsp;which is a scary thought.

Lata'

[drifterx]

i have X drilled on my car with metallic pads on my S13.... they stop great.... way better than stock......
did i mention way way way better than stock.....
the heat isnt an issue unless u race and do brake stands...... which i did but rotors are still find after a 7 months....
