Follow-up analysis to Car & Driver crashing Nismo 370Z at VIR

shabarivas · 04-30-2010, 03:54 PM

It honestly does not really matter about the justification... the driver obviously did not have the expertise to realize that the brakes were getting crappier... its not like it went from great to zero in one braking section... excuses excuses...

It clearly said the Corvette and Porshe did not have problems. I think it said the mustang Why did none of the other cars suffer as bad as the z did?

I think the article is probably right.

Funny how none of the other media outlets had or even reported issues of severe brake fade when they tested the car and that the probblem hasen't been replicated by anyone else. Doesn't the sport package have the same pads too?

Yes it does and they state that. READ

You know, 'vettes put the calipers toward the back side of the wheel (at least in front) - could that alone allow for more cooling? In the front of the wheel you'll have a naturally stagnant area behind the wheel...

I'm actually working on making a good DIY on brake ducting for the Nismo. I'll post results soon

If you boil the brake fluid you can have good brakes on one stop and pedal to the floor on the next, I've done it and it's not fun.

Their summary is correct, the brake cooling on this car is non-existent, one of the worst I've ever had. Normally you get some cooling in the vented rotors by the spinning cooling vanes acting as an air pump, but on our cars the aerodynamics prevent it from happening to much effect. I don't care if you have upgraded brakes from AP or Brembo, you have the same problem.

The next mod this car needs is brake vents, period. I don't understand why none of the vendors have stepped up to the challenge.

But vettes don't have brake vents...just calipers on the back end of the wheel...

That said, I'm all for a well-designed brake vent. It seems it would need more than just a duct to the wheel well to cool the front-mounted caliper area.

There needs to be a custom backing plate so the air can be directed at the hub and pushed through the vents.

Yeah, seem this isn't enough on its own:

Sure looks like a ton of air would be aimed at the brakes with that fascia.

Combined with a vented fender it would be a pretty serious cooling set up. I always likes the way 370Ztune's signature looked. Minus the flare this would look pretty sick especially if the vents were bare carbon and the rest was painted:

Or something more mild that would flow with the already vented rear Nismo bumper like the GTR has:

Anyone got a reasonable guesstimate on getting that Stillen fascia painted to factory colors?
