Although, exclusive of this Car and Driver/Nismo mishap, I don't remember reading a Z road test/comparison test that panned the car's brakes. Not saying these mags are the authority, but Id think one of them would have mentioned unusually bad brake fade/performance during testing.

Bottom line, though, if the Z's basic brake design/setup is a proven safety issue, the manufacturer should step up.

The G37 S has been mentioned to have bad brake fade and it has the same braking system. Seen it in R&T and C&D.

They don't make it anymore.

what he said, it was pretty good stuff for the price. And, when AMLS driver Shields Bergstrom did get my corvette fluid to boil a little, the car still braked for the remainder of the lap, and even when I drove it back to my paddock, nothing like the Z's total brake failure.

The good thing is, noone will ever get this problem on the street, at least if they aren't breaking about 20 laws at the time.

It's only a matter of time before we see a post from a Nismo owner complaining that he crashed into a curb while practicing his drift moves and blaming it on brake fade.

Ahhhh, gotcha - I know you were in the track game earlier than I was, so I understand.

I probably wouldnt worry a lot about running HP+ on a 'Vette - their brake system is so much better. This car...needs band aids

as I quickly found out! The car had 1500 street miles on it at the time, so the pads were as new. No pads should wear completely to the backing plates in only 20 minutes on any track.

No need to practice.... If you ever slided a car before, then Z is the easiest car to "drift". If you crash a Z, you're stupid and should not be allowed to drive over the speed limit ever again in your life, I have driven lots of cars and this is one of the easiest cars to push to its limits. I am sure stupid kids at some point will crash and blame it on brakes.... Happens with every car and every forum.

BTW what’s this animosity towards nismo owners?

To quickly answer this without going OT to much, so far the Nismo crashes (reported on the forum) have been from owners attempting dangerous driving abilities while on the street, be it drifting, street racing, etc.

On the brakes, great discussion guys, looking forward to what some vendors can come up with to help you guys out who track their car(s).

Don't know if anyone else answered this already, but according to the C&D article, it doesn't matter what brakes you're using. The problem is a matter of overheating, in their judgment, although it seems this is mainly an issue if you're putting your Z on a track.

The solution would be some sort of brake cooling modification. Tuners like Stillen may offer an answer via body panels that properly vent the brakes. The stock body panels focus more on aerodynamics for the purpose of fuel economy, but this leads to excessive heat build-up in heavy braking.

That's what I got from the article and this thread, anyway.

Kind of, but the added mass of my brembo gt calipers does allow me to do a full 30 minute session with no problems. I don't know how much longer than 30 they would last though, but 30 is enough

Nissan "the dealer" is NOT the same as Nissan "the manufacturer". You cannot indict the manufacturer for a "sales-pitch" made by the dealership. The dealerships buys the cars from Nissan, the manufacturer. The dealersships are customers to Nissan the manufacturer just as the person who buys the car from the dealership is the customer of the dealership.

So if the dealerships love talking up the Nismo as a "track ready" vehicle, that is a sales-pitch which needs to be sorted out and distinguished by the person who is interested in buying the car from that dealership.

So Nissan the manufacturer is NOT being misleading...the dealership who sells Nissan cars is being misleading.

I'm heading to Barber in June for a couple of track days.

Because I value my life, I'm taking my 1987 911 and leaving my 370 Sport Package in the driveway.

Maybe the Z would be OK, but I just don't trust it on the track.

The 911 is relatively slow, but it's bullet proof and the brakes never fade.

jabrother · 05-12-2010, 05:42 PM

Can't say that I blame you there!! At least til you get a pad and fluid upgrade in the 370.
