Brake cooling for Nismo bumpers

DarkJak

Are the GT3 ducts only mounted to the body, and not moving with any control arms? Just wondering how the mounting worked out. I have 3 sets of them as potential add-ons to various cars, and wasn't able to figure out a good solution for them on the arms, but your setup looks much nicer.

I'll plug my Pro5000R kit which has been taking a good amount of abuse well from a few track Z's this year, myself included. I have two sets of brackets and hats still, and with the USD being so strong, the calipers are relatively cheap to pick up compared to last year. Pricing ends up being similar to Stoptech Trophy brakes as a result.
Getting away from the Akebonos means being able to use rings that support a closer to 2" pad depth, vs the roughly 2.75" depth needed with the Akebonos. This lets the rotors be much lighter and opens up a lot more choices.

Super interested in any feedback you have on Paragon's rings. They come up as very enticing alternatives to some of the AP ones, being a little bit cheaper. I'd love to hear how to wear over track days. I have a set sitting around, waiting on some more niche (much smaller) Pro5000R calipers to be in stock for my Exige.

I'll try to take some more in detail pics. They are sort of hybrid mounted on the control arm and partly on the swaybar.

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.

Hotrodz has the ABS upgrade you want. Maybe one day he will get back on here to give some details. I know they installed extra wheel speed sensors. I am not sure how they did it. WRtechnica did the install. Getting the ABS module took a while due to COVID19.

It's a massive install that requires complete hub removal and machining to install the additional sensors. Car would be on a lift for 2 weeks at my shop. Not interested in going this route yet.

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!

Yeah, they went through hell getting his to work properly.

Im interested in the extras taken to help the ABS be more predictable.

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.

It's when both front speed sensors or both rear are showing different speeds under braking. Like the car is on ICE. It kicks the ABS system into thinking the car is on ice during a lockup. 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.

THE BULL

So from my research I've noticed the ABS needs at least two sensors for our speedometer to work. It could all really be software interpretation however if they're adding extra sensors it's possible they're supplementing the ABS unit with a more finer tooth count etc

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.
