I'm not sure the 1LE needs extra brake cooling

[seanblurr]

I roasted the calipers on my old SS 1LE. All the rubber seals melted and the calipers changed colors. Cooling the brakes was always an issue. Hasn't been as big of an issue on the ZLE, but I have yet to run race pads.

Lol. There’s a few folks who are actually saying this seriously.

My wife was watching me at barber during my last session (40-50 degree ambient), when i pulled in the paddock she said “it was cool i could see your ring things glowing!” I knew i needed some extra cooling then 😂

I've been looking for extra cooling since I saw that picture and you guys have nailed it

I think with stock pads and tires the car doesn't need more cooling for 20-25 minute sessions. I think 30 minute sessions are marginal, and anything non stock probably needs cooling.

However, I think there may be a misconception that the hoses will significantly reduce peak rotor temps under threshold braking. In reality, brakes need the straights with lots of air to cool down before the next braking zone. I would think these ducts help lower the steady state temps, which would mean either longer sessions or using higher friction pads.

FWIW, pretty much all race cars get their rotors glowing under threshold braking conditions, even with optimal cooling.

Not saying that this kit won't improve the cooling over the SS track deflectors, but i think it will not be a huge improvement. Read the brake cooling article here.

Not trying to hurt your sales or say that it won't work because it definitely will, but I am interested for your test results. These ducts will also have less drag than the SS deflectors for sure. I'm not sure if the SS deflectors create lift or down force either, so if they do create lift the ducts would be better in this area as well.

So you don't think air blown directly on the fire-path won't make a real difference versus air sprayed haphazardly in the general direction of the rotor?

Thanks for posting the article, but I didn't read anything in it that suggests that brake ducts aren't a better options than a piece of plastic zip-tied to the control arm. Also, a quick pass through the paddock at any NASA, SCCA, BMW CCA or PCA race would suggest that most racers believe brake ducts are the way to go, but to each their own. Great thing about freedom of choice.

These guys aren't making claims, they've simply built a product for those of us who already know that brake ducts are highly effective in reducing brake temps. They know there's demand. I for one will have a set and appreciate the entrepreneurs who go at risk to make stuff for my car.

I appreciate your feedback. We are only a couple months away from the next event, so please be patient with us until we are able to get more real world data. Great article from NASA, we will be using almost identical test methods for our kits.

Thanks for the kind words and support. We are always looking for ways to improve our cars, as well as our designs for products.

The reason the air deflector worked as well as their duct system is because of the location of their outlet. In that NASA article the air is directed at the face of in inner rotor and outside circumference. To get proper cooling the air needs to be directed to the center of the brake rotor and allowed to flow thru the vanes for maximum cooling effect. Their system was not designed and executed properly. This kit in the thread looks to be better designed at directing the air to the center of the rotor. I am interested in the results of the testing. If it tests come out positive, I'll be buying a set. Summer ambient temps here range from mid 90s to 110.

Read the whole thing top to bottom.

You are correct, I didn't notice how the small rotors in the NASA article are not allowing the duct to the center of the rotor. Also interesting and I don't think I've seen anyone point out is that the ZL1 rotors as shown here do not appear to be curved vane style like the 1LEs and use the inferior pillar vane cooling structure.

Yep, this is something that KNS Brakes pointed out to us the last time we met up with those guys. Rumor is that there will be a directional rotor option available in the aftermarket for us this year.
