Brake cooling for Nismo bumpers

Spooler · 09-13-2022, 10:12 AM

I am tired of lifting the heads on our motors. I am turning my power down and going a different direction so I can do some track days. I won't be a serious track guy, I just want to have fun. I want to go to Road Atlanta, Daytona, and Sebring. I live 30min from Roebling road.

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.

You will not be disappointed in your investment. It's the best brake system I've ever had, on any car.

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.

Car went back in the shop for the test fit last week. They were supposed to start today on it. First thing on the agenda was to test fit a new street kit. The 2nd thing was to install the competition kit on my car. Essex will not sale AP Racing calipers, rotor, or top hats separate. You have to order a complete front kit or rear kit from them once they ask you a few questions to ensure a proper setup for your future needs. The competition kits will be ready to order once they do the final fitment on my car.

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.

Spooler · 10-11-2022, 02:22 PM

The YAW sensor will activate the rear brakes, left or right, depending on what the sensor reads. It will activate the brakes of the inside tire to try and straighten the car out. That **** is dangerous as hell if you are on track. It happened to me on the Tail of the Dragon. I started to slide, counter steered into the slide, and the next thing I know the car snatched back the other way violently and damn near took me off a cliff.

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.

I turn the traction control off. I never ever use it. It's a throttle cutting beast.
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.

Here you go. New AP racing brake kits are done.

Yeah, my CP9660 kit is on the way. Went Front-only, I have the CP9660 caliper on my E92 M3, which is faster and heavier than the 370Z, and it works just beautifully. I'm still on the same rotor almost 6 years later, based on occasional DE use. The CP9668 caliper is awesome and uses the thicker pad, but the real key to this package is the 372x34mm 72-vane rotor. Can't go wrong with either kit!

So glad Spooler got his car in there!

It's a must, get that wired up.

Yup, I just got to cut a wire and splice it in. I will get it done. I hate that crap.
