Does anyone have any comparo information on the Brembo vs the 2005 coupe brakes? To be honest, the rotors look almost the same diameter and the calipers are pretty big in front of my new ride. I'm not saying the Brembo's aren't dope, but I just think the Stock 05' brakes are just fine for the street.

Do a search, this topic has been discussed before. Personally the Brembos were alot more substantial looking.

 

The brake pedal feel is different for sure.

 

yea brembo brakes give a whole different feel.....wen i got my 04 it was diff from my previous 330i

 

Ok, but I want to see some numbers and was just wondering if anyone knew. I searched for some tested numbers on stopping distance on the 2k5 brakes and the 2k4 brembos and couldnt find a good comparison. I realise Brembos are dope, but dont you think when it comes to street performance, they are about the same ( Brembos just looking a lot nicer!)

no doubt brembos look better, but in terms of performance they should be similar... at least in stock G35's

 

The brembos rotors are slightly larger and the calipers are completely different. There may be other parts of the system that are different as well, im not sure.
The brembo brake system is designed to resist fade more than most stock brake systems. It is not necessarily designed to stop in a shorter distance on one cold run. You would probably feel a difference stopping on the street, but it would just be in the feel. Performance wise you would probably not notice a difference until you do some hard driving. So while the stock 05 system may match the brembos stopping distance from 60mph-0 on one test, the difference would become pronounced on the second, third, and subsequent tests.

Having said all of that, the 05 brakes (and 03/04s) are more than 'adequate' for the street... so I definitely wouldn't worry about it too much, unless you're tracking your car.

 

thats funny casue the 6mt comes with brembos stock

 

the ONLY main difference between the stock 05's and Brembos is brake fading. On the track, Brembos will brake all day and not lose much braking power. If you take the 05 stock brakes on the track, they will fade faster.

On the street, there really isnt much of a difference performance wise.

 

now granted this hemi driver doesnt know alot about the brembo pack but i do understand something bout brakes in general. the more contact between the rotor to the caliper (or "brake pads") would mean more heat or "fade" rite? u want to decrease fade, get thicker rotors or ones that are slotted and vented. so less contact area betweent he two wont equal less heat? though granted i do see how over the length of the caliper the heat could disipate there, but i dont know the difference

my thinkin is the brembos were a great name until acura put them on for 2004 on the TL 6speed (or the most posuerish honda money can buy)

also i though the whole reason for the brembos was cause its a great four pot system.


ooooo by the way ive got some INSANE calipers on the 2003 that werent there on the 2001 my pops had. same wieght almost same rotors and HUGE difference in brake feel and a noticeable difference in the stopping distance even though ive got the old 20s on. now call me crazy but if the 19s on the coupe wieght more than that 18 and u give it less breaking power doesnt the whole system go mushy? hollla back

 

First of all, fade is referring to the reduction in brake performance as the brakes are used over time. (ie the first time you may stop quickly, the second, third, fourth etc will not be as quick as the last if you experience fade)

As far as what you said, I dont look at it that way. I'm no brakes expert but here's my take: the purpose of braking is to convert the kinetic energy of the spinning rotor to thermal energy (heat). If you have the brembo brake system, you're already getting bigger rotors (with possibly better internal cooling). The larger calipers of the Brembo system do have more contact area, and (probably) evenly exert more pressure on the rotors. This allows the heat to be converted to energy quicker because the heat is taken out of both sides of the rotor evenly, at the same time, and stored in an effectively larger area (pads). While the contact area is greater, thats also more space to store the energy that's being converted. I'm not sure if more material gives you a linearly larger amount of heat capacity, though. In any case, the overall temps per area of brake pad should be lower...

Brembo makes aftermarket calipers for many manufacturers, from Nissan to Ferrari. Not all are equal in the same way that not all Porsches are equal.

Thats probably a large part of it although there's probably a lot more to the story- i'm not a brake expert.

 

Did you not read correctly? 2k5 coupes DONT come with brembos.

 

I dont think he was trying to choose between packages as if they were available for the 05, but just wondering what the difference between performance was of the two.

 

Yea Sorry Bill Martin. Even i knew that. Dont worry I wont tell Dennis though.

 

You can brake all day on a track with the brembos and not lose braking power. At some point when the brakes get too hot on the regular brakes, you will have a hard time stopping. Brembos can take abuse and the regular brakes cant which is why brembos are performance brakes.
