Guys,

At the level I am pushing my car, the brakes are just simply getting TOO Hot. I already using Vented brake pistons, Girodisc Rotors, stainless steel brake lines DOT5 brake fluid, Cerakoted Calipers and rotor hats, YADA YADA. Calipers are getting about to about 450 degrees.

I need to get MORE air to the brakes. Anybody with REAL world experience using a brake duct system that EFFECTIVELY works????

I saw this below and I may try it but first wanted to check with you track rats on what you used and liked.

I used something very similar to that set-up on a Corvette that I used to race with NASA. It worked very well. I agree that more airflow is necessary when really hustling these cars. Post up your results, fitment issues, etc. if you go this route.

What kind of issues are you seeing? I've honestly never had brake issues and I always push the car as hard as I can. I've done up to 1 straight hour at VIR north before. It's this for the ZLE or SS 1LE?

I had to replace my dust boots this season because they really cracked and dried last year. Replaced them with high temp boots for this year.

It probably would have helped if you mentioned that your reengined car is now putting out 575 to the wheels and that you are running slicks. Lots more momentum that you are turning into heat in each brake zone. So the guys best positioned to answer your question are ZL1 1LE guys running slicks.

I can't speak to that brake ducting kit you are asking about, but it would be good to consider as well if the SS 1LE has the same air intake area on the front facia as the ZL1 1LE or whether it's possibly smaller. Having duct tubing from that kit might help some, but if the intake area is considerably smaller to begin with on your SS facia, you might be limited in what you can achieve with that kit. Another possible solution would be the CT5V Blackwing air deflectors, as they have a scoop section that hangs below the car as well as larger, sculped "air directing" section to maybe send more of the scooped and ducted air to the rotor.

If you haven't tried the SS brake ducts that could be a cheap first option.

Are you on the SS 1LE sized rotors? Upgrading to ZLE or larger brakes may allow for similar stoping power with less brake pressure.

Good suggestion guys. I fired off an email to the tech guy gut at RMMOTORWERKS to see if their system will work with an SS fascia. I will let you know what he says.

Well I have a NA 416 stroker motor that makes more power than a Zl1 1LE and from what I can determine from just asking around I brake MUCH later than most and HARDER.

But what issues are you actually seeing? Are you getting brake fade, soft pedal?

Caliper temps are around 450 degrees and I am NOT really seeing issues with brake performance but I am cooking the dust boots and going thru rotors and pads more frequently than I would like.

A decrease in these temperatures and I THINK I could see improvements in the longevity of these various components or SHOULD.

You're running ZL1 size brakes correct? No way should you be overheating those. I ran a similar hose cooling brake setup for about a year. Really didn't see much difference in cooling compared to the SS track ducts. What we did see was rubbing since there's not enough room for the hose a full lock. The hose became a consumable. This new setup hopefully is better than the old one. As a minimum you should be running SRF or similar fluid (dot 4, not dot 5), the small splash shields, and the SS track brake ducts or the new Blackwing ducts. The BW ducts are an improved version of the old SS track ducts.

I don't run with the center caps in the wheels to let them breath better. Its as much for the hubs as it is for the brakes. I have melted the center caps in the past so they get hot.

You could try the Cadillac CTV 5 brake air deflectors, while I have put them on my car at the recommendation of another member on this forum (TravisLambert), who does very in-depth testing, (he worked with a few companies to develop custom cooling parts for his car and also tried the big brake kit from AP and proved it does not cool any better than stock ZL1 brakes) I don’t have any data to provide or show in terms of how well they work, but it’s something you could look into if you want

YEP, I completely agree that is probably the best current solution and I ordered them about 3 weeks ago and they currently are still on back order. THX for the feedback. Once I get then I will take some HEAT readings off the calipers to see if they run any cooler. I am getting ABOUT 450 degrees at the caliper currently when I first measure then immediately after a session.

Yeah I'd love to see what data you get and look forward to seeing your temp numbers
