wow, not really the responses i was anticipating....let me interject with a couple things, i know upgrading tires, fluids, lines, pads will help...i also know that the akebono's heavy 1-piece rotors would be replaced once some nice 2-piece designs were available (same would probably go for the brembo's if i go that route)...what i would really like is a stoptech BBK f & r; however, the economical thing would be to go w/ brembo's or akebono's at the moment...i am not a track ***** but every once in a blue moon she will be pushed to her limits
...mainly i want the larger piston calipers, so i guess my real question is with similar rotors,pads,lines,etc which the better setup would be...if anyone has #s from the 04 coupe with its brake specs and a g37 coupe with its brake specs that would be helpful too (i know the #s would not be identical if transferred onto a g35)...on with the discussion

Did the op suffer from a mushy brake pedal? From stoptech. Also addresses the issue of smell. Could be a component of the pad, not necessarily the system as a whole:
MYTH # 3 - A SOFT BRAKE PEDAL IS THE RESULT OF PAD FADE
The all too familiar mushy brake pedal is caused by overheated brake fluid, not overheated pads. Repeated heavy use of the brakes may lead to "brake fade". There are two distinct varieties of brake fade
A) When the temperature at the interface between the pad and the rotor exceeds the thermal capacity of the pad, the pad loses friction capability due largely to out gassing of the binding agents in the pad compound. The brake pedal remains firm and solid but the car will not stop. The first indication is a distinctive and unpleasant smell which should serve as a warning to back off,
B) When the fluid boils in the calipers air bubbles are formed. Since air is compressible, the brake pedal becomes soft and "mushy" and pedal travel increases. You can probably still stop the car by pumping the pedal but efficient modulation is gone. This is a gradual process with lots of warning

What is the weight different in calipers?

When people go with 18 inch rotors 16 piston BBKs, there is really no point besides adding rotating mass and slowing ur car's acceleration. 13-14 inch nice brakes are more than enough for our 3400 lb cars. I have done lots of comparison with very close people including back in 2004 with Rob_G35's 2003 G35 6MT coupe. There is a particular road that will wear heat ur brakes up with constant 70-20 mph slow downs every 10-20 seconds for about 10 minutes strait and his bone stock OEM brembos actualy held up better than his 2005 s2k that we tested two years later.
I just wanted to know your reasons for stating the Akebonos weren't track worthy while the brembos are. Both feature fixed 4 piston calipers. The only diff I see is the Akebono 14" by 13.8" rotor size. If the oem brembos were up to the task, I don't see why these wouldn't be.
IMHO, the larger mass of the 14" inchers should have given him more heat capacity.
I also don't quite 100% understand the specs of both systems. Akebono was 100% stock right down to the pads. Yours? You have aftermarket lines, fluid, rotors. But on oem brembos? An direct all oem comparison of the brembo/Akebono setups on the same model G35 coupe or sedan (on similar wheels/tires) would have been cool to hear about.

IMHO, what he might have experienced was from either not running fluid that was appropiate to his application or the oem pads weren't meant for the duty he put them though. It's still not clear as he states the performance wasn't affected. The crappy thing is I don't think there are any performance pads available. But I'm sure their will be soon. Can't see these great brakes not getting a 2pc version or aftermarket pads soon. Racing Brake will probably be the 1st to offer a 2 pcs as they offer 2 pcs for the oem brembos.

If i was in OP's position i would get the g37 brakes since they do look better than the brembos.

Actually my ideal setup (for me) would be a set of OEM brembos with the RB racing 2 pc rotors. I think THAT would be a kick arsed track bbk setup as you get to retain the oem brake bias.
But I commend you for getting such great performance from your oem floating piston setup. You on the pre-05 11.5" rotors or on the post-05 12.6" units?
