It didn't take long to screw the 2003 owners.

Tandem master cylinders? I wonder what that'll do for braking? Anybody know how two aids in braking?

 

Quoted by Autoweek:

NISSAN WILL FOLLOW UP its successful launch of the 350Z coupe and roadster with a series of running changes that will appear on 2004-model Zs now arriving in U.S. showrooms. Nissan already incorporated most of the changes into Japan-market Zs, including significant interior upgrades, suspension tuning and brake system improvements.

Inside, Nissan focuses first on the front and center console, specifically the flimsy, manually operated upper instrument panel compartment cover. The new lid is more robust, with power operation on cars with satellite navigation. The center console, gauge hoods and instrument pods get a special “soft-feel” treatment intended to inject a touch of higher quality into the interior.



And how about this for those road warriors who’ve grown weary of bruised extremities: ’04 Zs come with cushy kneepads for both driver and passenger, and the driver’s right elbow even gets its own special padding on the center console. Further interior updates include the addition of seatbelt “service arms” that eliminate the need to reach far behind the seatback to grab the belts, and a redesigned shifter for automatic models.


2004 models also benefit from Nissan’s decision to adopt a Euro-tuned suspension setup for all 350Zs, a handling setup that Nissan says provides a much better ride and better overall suspension compliance. The Brembo brake system gets tandem brake master cylinders replacing the earlier model’s single cylinder.

 

How do we retrofit our car with "Euro-tuned suspension setup"??

Has anyone check the part number and compare the difference between the US and European 350z's? Is it the springs? or is it the shocks?

 

Taughter springs, re-tuned shocks, revised bump stops (effective over wider range of travel), sways are (guessing) the same.

Don't know. Nissan changes the part numbers on our springs a couple times i beleive, so it will be hard to go about it that way. Id wait a few months until the new 350z w/suspensions start to ARIVE at the dealerships, then order the newest suspensions parts.

 

I knew in advance of this article that they had done some changes. Simply went on the logic that every single roadster review paised the suspension for it's ride quality. I knew they had to of changed it. So, when I was in my local Nissan dealer getting a part I had them search the computer for any difference in part numbers from 03 and 04 springs and struts. The computer showed no difference as of last week. Either means they changed it and didn't feel changing the part numbers was warranted or they haven't gotten to making the redesigned parts avaliable through the parts system. Either way, not firm answer yet.

 

The funniest thing is that they used us original owners to get the feedback to make these changes.

 

I would like to know more about the tandem brake master cylinders on the track models.....does the single not hold enough fluid or provide enough pressure? I have not noticed any problems with my stock Brembos, has any one else? Why would Nissan change this if thier was no problem with the single system?

 

i wish i could find out if i have any of these upgrades. i have a 2004 track thats about 2months old and came straight from japan built for me. is there anything or anywhere i can enter my vin # and see?

 

if you are not having any problems, then you are fine... even if it's older spec, Nissan is not going to change it out for us...

it will cost them major $$$ to do this... since they said our car has NO PROBLEMS...

 

I dont know if its just my pads or they need to be bled, but sometimes my BREMBOS feel alittle weak. I find I have to pump the brakes once or twice to get them to firm up. Anyone else notice the same? I have just under 9000 mls.

 

I only have the front ones, but they stop great, I would bleed them just in case.

 

 

me too. but i have a touring and installed them afterwards.

 

I noticed a slighlty soft pedal feel (not weak braking) that can get firmer with a pump or two. I think it's the normal feel of the brakes.

 

check the coupe forum.... same information being requested with some answers..

Still waiting for info on the Brembos... what the hell is on going here ??


TCL.. looks like a go for you with the S-tune if you still want it...

 

My guess is that tandem master cylinders let you pump more fluid with a shorter stroke (less pedal travel).

Since the Brembos have more pistons they need more fluid. Maybe someone decided the pedal travel should be less.

 

I really don't think that the pedal travel has anything to do with the master cylinder or the pistons on the brembos. I think it is simply related to the vacuum-based brake booster. When you pump the pedal once quickly, you are hitting the brakes without the booster and you get less travel. Try pumping the brakes slowly. You will notice that the pedal travel remains the same. I think this is because the vacuum in the brake booster builds back up again and you get the regular travel. Just my opinion. I very well may be wrong.

 

Hunter, I agree.

What is with the Brickyard pic......I thought it was not available in "94?

Does anyone know the part #'s of the "euro" suspension pieces?

 

Thanks. Right now my plan is to go with the NISMO sway bars and Koni shocks instead of the full kit since the car is already low enough that it barely clears the lip of my driveway.
