:germanflag: God i cant wait till it comes out, i am so psyched and i cant wait to see it come stock with some nice ass cross drilled rotors mmmmmm..... and a V-8 churning out more than 400hp mmmmm :bow: :drool: :alright: :boink: :headbang: :clap: hahaha ok enough of my ranting

thats hot.....the fenders are nice and wide

[LDadrenaline]

Cross drilled rotors suck, you need slotted. Drilled ones crack during extended amounts of intense driving.

edit: but yes the new 3 series is gonna be hawt

[JonnyChimpO]

hottness.

[kelso]

only crappy rotors that are actually "drilled" will crack. the ones created with the holes already in them are great.

[LDadrenaline]

They actually aren't all drilled.... I know one of the porsche guys with a cabriolet was telling me the only rotors he can get for his specific model are made in a mold with holes instead of being drilled.... and yes, he said they still crack.

i have heard that cheap cross drilled rotors are the ones that crack... ive never heard of Brembo, Willwood and some of the other more expensive ones cracking or having any problems

[LDadrenaline]

Well then I ask you, why do you not see almost all of the professional teams using drilled rotors? All the guys I know that professionally race use slotted rotors.... The drilling doesn't really help with cooling that much. What it does is get rid of the gas produced by using the brakes which can cause them to retain heat more. Slotted rotors do almost the exact same thing.

i have never understood why slotted rotors can do the same thing that drilled rotors can when they just have slots no holes or anything... can anyone explain how that works out?

[RPM Photography]

The way I understand it, gases built up betwen the rotor and the brake pad.

Work with me on this one, drilled rotors "funnel" the air out and slotted rotors "channel" the air out.

I beleive.

ah ha now that makes sense... but wait how does it get out of the slotted?

[LDadrenaline]

The brake pad only covers about 1/3 of the rotors, so the rotor "sweeps" the gas out. You don't constantly have the brakes applied, so when the air goes over the rotors it gets rid of it.

[kelso]

but a lot of companies like ferrari porsche and even bmw all use drilled. i have never heard of a quality rotor cracking but thats the reason people in the aftermarket are willing to pay extra to get brembo or wilwood. those are good companies and pricey but they wont crack. its the cheap ones that always do.

ld what professional teams do you mean exactly cause most companies i know use the drilled design.

[silver-e34]

there is no such thing as molded drilled rotors.drilled rotors dont just dissipate the gases but it also cools down the pads and rotors by having freash air flowing thru them the slotted rotors only dissipate those gasses but doesnt do much for the cooling process. the reason why the cheaper rotors crack is because they are drilled improperly straight thru from one side to the other and that doesnt do anything for air flow cooling and just makes the rotor less stable the quality ones are drilled on an angle for better air flow and less heat means no cracks

[silver-e34]

[LDadrenaline]

no such thing

Yeah I didn't think so either, but apparently there are. Someone who runs the PCCA was telling me that for his cabriolet model thats the only ones they make and that they're not supposed to crack because they're from a mold not drilled, but they still do. I can try and look for the molded ones but he did definately ssay they exist.

[AwesomeBMW]

well there goes my idea of drilling my own rotors hahaha wow im a retard... I deff want some Brembos though, cross drilled preferably bc i have herd great things about them and ive never heard of them cracking... wouldnt it be great if BMW started offering Carbon Ceramic Brakes as an option like Porsche and Ferrari? it would be expensive to make and have as an option but if you want to race your M3, M6, M5, Z4 M Roadster/Coupe than you probably save money :dunno: although Ferrari's cost 16,000 dollars

[LDadrenaline]

Just get slotted rotors and cryo them, get stainless brake lines, then take out ur fogs to make brake ducts... Problem solved, thats enough cooling for your brakes right there

You know of a porsche guy with a cab who was telling you that he can only get a mold...
wow.... honestly, interesting ****. you know some guy who owns a porsche who said something. Hey, if he said it, then hell it's a god damn fact. :roll: :roll: :roll:

Honestly, I'm about to flip out with the most of the **** you've said in this thread..

Let's see.... since Brembo supplies the most high performance pads and rotors to the best performing cars and bikes, ferrari, porsche, ducati, and no one there has had any complaints (except for the once in a blue moon defective products) , most love there brakes. And since the majority of racing vehicles, whether it be moto or f1, le mans, amercian, whatever, the majority uses brembo, and most use, slotted, drilled, both, etc..

All the guys you know? Last you said was some porsche guy with a F U C K I N G cab at a meet.
Honestly, if someone cared that much about performance, they wouldn't buy a cab since the overall strength of the vehicle would be impaired..
Not trying to rip on converts, but if your talking about all out performance, you don't buy a cab... :roll:

If they're cast drilled, like brembo, then they do not crack.

If they're cast drilled, like brembo, then they do not crack.brembos are not casted they are drilled :banghead:

[TheDarkSide]

I wont question Gus's knowledge but I was told companies like brembo used some sort of cast :dunno:

[kelso]

i have heard a lot aboutmolds as well? and yea i just remembered most motorcycles have drilled rotors too. my dads bmw for example.... and virtually every streetbike you ever see and race bike...

[AwesomeBMW]

actually something that is funny to me right now with everyone talking about Brembo, i read in a Car and Driver the issue that they tested the E60 M5, the STS-V and the MB CLS55 AMG, they said the Cadillac had stronger brakes that didnt fade as badly as the MB and the Caddy uses just vented Brembo's where as MB has theirs cross-drilled.... HAHAHAHAHA MB SUCKS!!!:lol:

[kelso]

but doesnt the caddy have bigger brakes? besides that sounds like more of a braking system issue anyways instead of a rotor issue. plus you gotta think about how much weight each car is stopping

[AwesomeBMW]

that is very true and i think the Caddy's brakes are just slightly bigger, i will get the numbers and get back to you on that one...

[kelso]

amg should know better:nono: and they should have the best stuff. im not really a mercedes lover and i doubt i would get one, but the amg's are some sick cars. automatic ftl

[AwesomeBMW]

found this today on GermanCarFans.com... it is the new M3 Coupe/Sedan, i like it but i dont know how about the front fascia on the Sedan but i trust BMW and im sure that they will make it all work... sorry for the link the pictures wouldnt save onto my laptop so i cant host them http://www.worldcarfans.com/spyphotos.cfm/country/gcf/spyphotoID/6060330.002/bmw/more-bmw-m3-coupe-and-sedan-spy-photos

[AwesomeBMW]

amg should know better:nono: and they should have the best stuff. im not really a mercedes lover and i doubt i would get one, but the amg's are some sick cars. automatic ftl
i agree you would think AMG would be the best especially for the price but an M3 ould take a CLS44 AMG on the track all day long and that suprises me

[AwesomeBMW]

hell i think my 330i would do better on a track that my moms SL500S and she has cross drilled front rotors 255front and 285rear tires just like the SL55 AMG... but her car feels so awkard and heavy and its so annoyingly tamed and there is no feedback in the pedals nor the steering... so i think that i could either tie or come very close to the time of an SL500 on the track in my car (probably not with me driving it though :lol: ) her car has 77 more hp, 125 more lb-ft of torque and 2 more liters with a V-8 to my I-6, but er car does weigh about 1,000lbs more than me but still that is no excuse for a car that has twice the technology that mine does

[kelso]

i dunno why but i think i almost like the sedan more than the coupe?

[SlickShift]

Soooooooo...about that new M3 :focus: :clap: :thanks:

[AwesomeBMW]

i dunno why but i think i almost like the sedan more than the coupe?
actually in terms of the E90/92 i like the Coupe better this time around but for the E46 Sedan FTW!!! and the E36 Coupe FTW!!! I had a 1996 328iS so i thought the Coupe looked better for the E36 but ive always thought the E46 Sedan was more balanced than the Coupe but the E92 looks more capable than the E90 althought the E90 330i Sport is AMAZING!!! so much faster than mine a huge difference

[AwesomeBMW]

Soooooooo...about that new M3 :focus: :clap: :thanks:
i agree... im done :rant:ing about MB and my car versus my moms

[Roy]

:cry: :cry: :cry: :cry: :cry:
Dude, I know you didn't buy a cab for overall performance..

it's all about the bitches..:bow:

[kelso]

bitches and whores bitches and whores, all i see is bitches and whores....

anyways i think i need to just see them in person but from the pics i just think the sedan looks cooler.:dunno: thats just me

[silver-e34]

I wont question Gus's knowledge but I was told companies like brembo used some sort of cast :dunno:http://www.brembo.com/Brembo/Templates/FAQ.aspx?NRMODE=Published&NRORIGINALURL=%2fUS%2fPerformance%2fFAQs%2f&NRNODEGUID=%7b1E036965-CEF7-409C-97E1-7B3E70A299EE%7d&NRCACHEHINT=NoModifyGuest that might help you out some dave :cheers:

[TheDarkSide]

:thumbu:

[E31]

It looks fantastic! I like the 7 series lights on the back as well. Can't beat a V8 under the hood. That way someone will drop some turbos or S/C in it.

[TheDarkSide]

Hood looks weird...looks welded on.

Yea Porsche is stupid for drilling their brakes...No wonder porsche brakes suck, especially the Carbon Ceramic ones:roll:

quotes from the FAQ on brembos site:
Are discs with cast-in-place holes better than cross-drilled discs?
Brembo has extensively studied and tested cross-drilling versus casting the holes in place and found no significant effect on performance or durability.





What are the advantages of drilled and slotted discs?
The main advantages of drilled and slotted discs are the same: increased brake "bite", and a continuous refreshing of the brake pad surface. Drilled discs have the additional advantage of being lighter and running cooler. However, there are certain pad materials that should not be used with a drilled disc.

[AwesomeBMW]

id still rather have cross drilled bc you save a little more weight and to me it makes more sense bc it dissipates the gasses and heat better by having holes

See well that proves that casted ones do exist with holes lol.... But yeah I never thought of the cracking reason may be the certain brake pads. Although, that may be a way of saying that higher performance brake pads heat up the rotors too much causing them to crack....

[catchuk]

i dunno why but i think i almost like the sedan more than the coupe?

I kinda agree. I really like the sedan, but the coupe isn't all that exciting to me. I think the e46 m3 is much nicer.

[TheDarkSide]

We have all said that we hate every new model but it grows on you I think :thumbu:

[prophecy]

man i dont like the new coupe at all. is it just me or does the rear look like a mb

[TheDarkSide]

reminds me of like an RL

[JonnyChimpO]

well i like and dont, i guess its gona grow on me, but a v8 is how might i say......"OH noesssss."

[SlickShift]

I'm kinda sad BMW is going away with the I6 in the M3. The inline-6 is the BMW staple. :think: *mid post re-though* :think: I just remembered the S54 was the pinnacle on I6 engines and it cannot be further improved!

[E31]

Cast-in-place holes are the way to go if you want the holes in them. Some companies buy stock Brembo brakes and slap a template on them, then drill the holes into them. The random holes sometimes hit the structure of the vents/canals inside the rotor and weakens their structure.

Racers buy sloted and drilled for cooling and weight reduction. They can do this since they change out their rotors frequently. I have seen rotors break apart and crack at the track....not a nice sight. For our applications, slotted is enough. The slots keep the surface clean and let the gas buildup escape through the little bubble that the slot creates while turning and pressure is applied. They are not "cheese graters" like some people call them.
