I was wondering if any one on here ever made that attempt? If it bolts up or not? Think would look nice seeing that gold with red letters... Guess that's gonna be in the R&D phase as of the moment...

according to the 350z forums the 05 are larger than 03 and 04:

specs of 05:

4-piston calipers with 12.76" x 1.18" vented front discs.
2-piston calipers with 12.68" x 0.87" vented rear brakes.

hmmm... rotor thickness is thinner compared to ls400 and supras?

 

 

i would be more then glad to do the R&D for you if you buy a set, send it to me, and give me a little bit of time to test fit and/or make custom mounting brackets.
how much do they go for anyways?

the one thing you need to consider is the brake bias. you usually cant just throw on a set of calipers from a totally different car/application/size and expect it to work well.

the master cylinder will need to be replaced in order to have the system function 100%. otherwise you can have deal pedal feel followed by sudden braking.

the master cylinder in every car is made to activate front or rear brakes at a certain PSI. that depends on the engineers specifications at the time of the vehicle production.

if you were going to use the brembo setup from the 350z and made the brackets to bolt it up the best way to make sure it works properly is to move to a dual master cylinder setup like an AP or Tilton.

that would be a lot of money and most of the time not worth it unless you get a great deal on the calipers and can do all the fabrication work yourself...and have the time to do it.

btw rotor thickness is not as critical as the actual diameter. if you have a bigger rotor you can generate more brake torque. if the rotor is thinnner it has a chance to overheat easier but with proper brake ducting it should not be an issue.

 

boy, sounds more complicated than I imagined... Haven't went to see an average price for a set of used ones go for yet... Then again not like many 350z and g35 owners that came with a set not really likely to part that out unless they feel it's not giving them the stopping power that they need... but even i'm sure if they found a set from a wrecked one, i'm sure it's still expensive and those owners that don't have a set, more likely to scoop it up fast... thanks for the info...

 

05 g35 dont come with brembo.. so if they say if from 05 g35 is a lie.. coz i got rotora 6pt on my 05 g35..

 

only the hightest models g35's have brembos.....

 

I believe after 04 they stopped putting brembos on the G35s. And unless you have an arm and/or leg (around 1000 for the fronts on a good day) to give up than just go supra brakes

 

The Supra TT brakes are four pot calipers with 12.75in front rotors. Sure the Brembo name might be worth the bling but I believe the performance is going to be similar.

The Master cylinder doesn't apply different pressures to the front or rear brakes, they both get the same pressure from the master cylinder. It's the proportioning valve that limits the pressure to the rear.

The two circuits in the master cylinder aren't front/rear, usually the brakes are split side to side so one front and one rear brake are on one circuit.

Most people who have done the Supra TT front upgrade and left the rear the same haven't had any problems. I certainly haven't. Not sure what it would be like on the track though.
