You may recall that C&D smacked a Nismo 370Z into the wall at VIR a few months ago and promised further analysis of the root cause. Here's the thread on the original accident: Car and Driver Crashes a Nismo 370Z

Here is C&D's follow-up:

The back end on a Nismo already has slots in the rear bumper, which should create negative pressure behind the wheel well and pull cool air into the cavity. However, the front fender has no such slot. Hrm...

30-40 stops from 100-0 right after each other....??? Wtf are these guys smoking? The most demanding tracks in the world will not require 100-0 stops right after each other 30-40 times without a minute or so. Lower speed breaking and straits will be more than enough to cool the breaks in the process.

Raced a 335 recently "in a closed legal location" half way through the 10 mile race his breaks started to fade and mine weren't even smelling. Obviously he was harder on breaks to keep the pace going but it still doesn't explain the BS that this article is spitting out.

BTW yes my oil temp did go up to 260 3/4 of the run.

It was just to determine at what point they start to really fail

From reading the whole thing it seemed like they were trying to justify why they crashed the nismo in the beginning. No modern car will all of a sudden not stop during a hard breaking. Before not stopping there is such thing as smoke, longer pedal travel, and longer stopping distances called "fading" which gradually build up during hard driving. They obviously ignored those signs and ended up crashing the car...

time for modshack to divert his intake duct to his brake duct.

I say we push Stillen for a group buy on their new front fascia.

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...

Forrest

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?

in for updates and a link to the stillen fascia

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...
