My NC has bigger front rotors than my Dakota R/T. I've managed to make the brakes squishy in the Miata; the Dakota has seen flickering orange flames on the pads.
So thanks, Keith, for the tech tips to improve my Dakota. Lol
It might be worth it to make a little grate to keep little critters and debris out
Great video. Thank you 😊
Glad it was helpful!
So I’m curious about using this same setup style but for an improved intake snorkel on a ND2. BBR has their version of it, do you think it would actually flow more fresh air?
I've heard anecdotal accounts from other drivers that when they got the right brake rotors (72 vane iirc) they no longer needed brake ducting on track.
Rotors can only move the air that's already there, they can't bring in cold air from elsewhere. If a car is just barely overheating the brakes, you might get away with a rotor change to a magic rotor. But they're no replacement for a strong flow of ambient air.
I don't have a miata but I've got a mr2 spyder and that 2nd duct that was shown looks like it'll somewhat fit my 02 stock bumper since I have a inlet that air goes in and does nothing.
We've never tested fitment on an MR2, so we aren't too sure.
Hi from Spain.
I want to install a ducting for brakes but I have the Racing Beat nose. Do you know some duct like the 3D R-package version but for RacingBeat nose?
We don't know of any. You might want to check with Racing Beat to see if there are any ducts available, otherwise you'll have to make your own.
Have you tested naca ducts that would be located on the hood? would they generate enough air flow? I see them on the Porsche GT4 RS
We haven't. The routing would be pretty bad to get cooling down to the rotors but it is a high pressure zone.
How would brake duct perform in the rain tho, my thoughts are they will cause the rotor too warp from the water reaching it with the added cooling
Good question! Since we're only talking about a little bit of water unless you plan to forge rivers, the water will rise in temp the closer it gets to the rotor and once there, the difference won't be enough to cause issue with the hot rotor. If you're not able to keep the pads in their temp range due to cold weather or rain, plug or reduce the duct inlet.
Is it better to duct cooling to the front brake rotor or the caliper?
The center of the rotor. More details in the video!
Thanks for the advice. I will change from trying to cool the caliper on my race car.
Hey Keith....totally off subject. You have a skid plate surrounding the rear diff and exhaust. Was this DIY or is there someone making it? I have a Getrag diff.
This car was originally built to do tarmac rally, so it has a well-armored underside. Most of the skid plates have been removed but that one is still there. It was a DIY job based on a 2001-05 rear subframe brace with UHMW sliders.
Great generic introduction. Thank you.
Thanks for watching!
