For what its worth I have had no heat issues with my brake setup on the track and I have put them through some serious abuse the past few events. Not even a hint of fade, stock rotors look fine, pads look great, etc. Here's my setup...

Stock sport pkg. BBK
Stock rotors
Challenge SS brake lines
Carbotech Pads (XP10 front/XP8 rear)
AMSOIL fluid

I don't really think front brake ducts are necessary personally. At least not until these cars start getting much faster. If someone gave me a set I would use them, don't get me wrong, but its not on my to do list yet.

Have you inspected your calipers for damage to the boots? I think it was Mike that managed to cook his off in one day.

I haven't looked in there after these last two events, but after my first 3 events they were fine.

To be fair, it does depend quite a bit on:

The track - obvious

The driver - good drivers will hit higher speeds and need more brakes, *some* bad drivers will just be more heavy on the brakes

Tires - R comps are going to put *way* more heat into the brakes if you are at threshold, and I think the guys who have had the most trouble have sticky tires.

If you haven't seen it - Jalop just posted a nice photo of the brake cooling on the GT1-Spec Nissan GT-R:

I believe that we are going to be developing a kit for the brake ducts soon, but we are in need of a track oriented test bed 370z. As for the amount of air moving through the brake ducts there would be little to no amount of lift involved in aerodynamic loss because of the fact that the air would be traveling through the rotor and out the wheel instead of under the car itself.

You live the closet to Corner3, lend them your car for a while. ;)

Can't really talk about it.. but we have some aero pieces coming soon that will definitely address this.. :)

More info soon..

Sweet - thanks for the heads up!

I'm not convinced I want to do the whole front fascia, but I'm definitely curious about what y'all have got going...

:iagree:

Any update on the development of these types of kits and/or aero pieces Josh was referring to?

This is the first time I have seen this thread and I would like to add my input if you all don't mind...

There is a lot to consider when looking at brake ducting. Something like Modshack posted might look pretty ghetto but it will be functional. If you look at a lot of professional race cars they simply add little wicker bills on the lower control arms just to "scoop" some airflow into the brakes. This is one of the many things we did on our Ford GT rally car in fact. We just built little rubber blades and drilled them into the lower control arm and they worked very well.

If you want to make the front fascia fangs your airsource you would need to see what size tubing you can fit up there. For starters, 2.5 inch is the minimum of what you can consider to be "acceptable." Anything smaller than that and you might as well not bother.

Second, take a look at your routing. There is a lot going on back there and you need to route the hoses around coolers, chassis braces, and most likely you will need to cut a hole in the fender well to gain access.

We are going to work on an active cooling kit for our car. Basically I'm going to take the cooling kit that we make for the GT R and make it fit the Z. It isn't cheap but it is incredibly functional and has electric fans and everything...This will be for our race car.

The front fascia is coming along nicely and will be done soon. The brake duct accessory pieces will be available at the same time as the fascia.

Thanks for the update Kyle!

I think if you found a wayto attach air guide to the already existing undertray, you'd be ok. There is already air flowing under the car... if you had a way to evacuate it into the rotors, you might even help with downforce... like this
