Other then you asking why, why are you asking? I have friends who have the Brembos on the G35 and they all have problems. Not sure why Anywho, in terms of braking power for the normal person, both are fine (although the 05-06 stock are much better then the 03-04's). However, if you track or do alot of braking for whatever reasons, the Brembo's are the way to go. Also, only the non-Brembo rotors size increased in 05.

Now, that being said, if you have a choice of upgrading your brakes, then definitely get some BBK (like Stoptechs, Project Mui (not sure of the name), etc.) and don't get the stock Brembo's. Why on earth would you pay alot more dollars for stock Brembo's if you can get better brakes for about the same or even less? Anywho, I had a choice also and decided not to get the 04 (even with a great deal) when I bought my 05 (for the reason above with my friends Brembo's brake) and other refinements in the 05. I knew I was going to upgrade my brakes so it'll be a waste to chuck out the Brembo's (which MIGHT be the only reason to get the 04). Like the other poster said, the damn ugly gold color! Why or why gold? Red or even black is much better.

Hope this helps.

 

Please learn how to spell. It is BRAKE not BREAK

 

Geez... At least I got it one time right!

 

Looks like the 05+ G's get similar sized rotors but just a tad thinner and smaller in the rear. Plus dual/single vs quad/dual pistons.

This leads me to believe that if the Brembos indeed have more piston area vs the stockers, they will stop slightly faster due to more clamping force.

The thicker rotor will allow the brakes to resist fade more. The more pistons should help with braking MODULATION as well as more braking force (if the area is increased as mentioned)

IMHO. It looks like a 05+ brake upgrade to a 03-04 non brembo G looks like a real nice upgrade. Especially if your car is mostly street duty. These brakes should give 95%+ of the performance of the Brembos in 1-2-3-4 panic stop situations but w/o the cost and wheel fitment issues.

As far as aftermarket bbks being superior to the OEM Brembos, that might be true or not true. One would have to examine the rotor size and total piston area to determine if they do indeed offer superior braking ability or not. I suppose they would as it wouldn't be much sense to make a bbk that didn't

 

My thoughts exactly. I guess it all boils down to the same reasoning: Since the BBK has larger rotors, more pistons (assuming you get the better BBK), then they SHOULD perform better. Then again, I'm sure the costs are less then the Stock Brembo's so why would you even get the stocks? But man, just one look at the Stoptechs and Project Mui will convice almost anyone to get one (even alot of the Brembo's owners too).

Come to think about it, when you start getting into the BBK's, I don't think it is about shear stopping power anymore. I think it is about fade, looks (and they do look nice with the slotted/ported rotors), and realibility (able to stop consistently after many hard brakes on a track for instance).

 

Well you have to quantify your statements a bit: OEM 05 vs OEM brembos

Fronts are slightly bigger. Rears have bigger diff. But not THAT big of a difference overall.

Means only better modulation. Not necessarily better performance (stopping power). ONLY if the total piston area is LARGER than the dual piston. Both "could" have the same piston area. ie.. 2 large pistons vs 4 small pistons of equal total area = equal total clamping force.

Should but by how much is the question.

Reasons NOT to get the oem brembo/aftermarket bbk. High cost is one. Difference in street applications might not justify the cost is two. Replacement rotor costs if the units are 2pc. You ever research 2pc rotors? Try $500+ per pair! Wheel fitment issues. Replacement pad cost / availability.

 

So if I want better braking performance out of my car for not that much of a cost the 05+ brakes would be good deal? How is the brake fade compared to the 03 and 04's?

 

I have to admit I was getting a little bit off topic here (sorta). That is why I was asking the original poster what he/she was asking the question for. I think if you already have the 03-04 without the Brembo's, I don't believe you would want to upgrade to the 05-06's brakes. If you are going through the trouble, I you should get a BBK. That's the point I'm making here is that the BBK will give you at least the braking power (and other things of course) of the 05's and Brembo's. Upgrading to the Brembo's (at least the stock ones) is expensive and will give you very little over the stock 05's unless you are VERY hard on your brakes (e.g. tracking your car). I'm not even sure what the cost is to convert your 03-04 to 05+ brakes. That is a good question though. I mean if it is less than $500, I say that isn't a bad deal.
