Brake cooling for Nismo bumpers

So far that Paragon rings have been great, all their rings use the same motorsport quality material. The fact they can provide a 72-vane rotor for sport brakes is a great benefit. As you know, going from 48 to 72 vane is a BIG step up in thermal capacity and longevity. It's going to be good enough for most of the DE guys.

I'm a hardcore track guy, but I spread out my track miles on various cars, and until I get the ABS situation figured out, the Z will see limited track time until then, and my current setup will be adequte.

When you push this car to the limit, it's just too inconsistent with potential for a catastrophic failure by the ABS. My local tracks have too many brake zone that bend, that are exactly what this ABS system hates. It's not fun to have the baby the car into a bunch of corners to keep it from trying to kill you. If the front-only kit gives the car a bit more front bias, which this car seems to need, then I might bite, but will wait and see how things pan out.

I am sure it can be done another way (electronically), just waiting for it to surface, or I get the time to dig into it myself. Just super busy with other stuff right now!

What I guess happens is the OEM sensors especially in the front give an improper speed with the flexing of the front hub?

The factory ABS unit cannot take more that 4 speed inputs unless theyre supplementing the oem ones or upgrading them to better sensors.
Our ABS unit seems to be the same as some Subarus of the same year.
So it makes me wonder the specifics.

I was under the impression it was issues with the YAW's sensitivity more than improper wheel speed.

I am not sure how it is programmed into the ABS control module. There is a problem with the algorithm they are using from the factory.

I too dislike the ABS engagement of these cars. I was under the impression ECUTEK's adjustable traction control capabilities would help it's over reaction by softening it's traction control to one a bit more decent.

I still need to do the Yaw sensor switch to turn that crap off too. I just need to wire it up. My switch is already in place.
