Brake Ducting

Anyone running any ducting on a first-gen and can show me an example? I'm interested in seeing how anyone else has done the ducting.

 

Thanks in advance.

You planning on racing the car or running it on the street? Ducts are helpful if your racing and driving/braking to the extreme. There just garbage / dirt collectors on the street.....just a thought.

Ducting on a street car is a real pain. The ducts get smashed/scrapped off in tight turns and tend to fall off over time. Basically you run a 2" duct from an opening in the front spoiler, under the radiator core support, against the inside the fenderwell, and then out to the brake from above where the lower control arm is.

What John Said...

 

I removed mine when I wasn't at the track... Nothing more embarrassing then having some hot babe waving you over, only to find out that she wanted to tell you that your car is DRAGGING parts. :roll:

 

Don't ask how I would know about such things! :lol:

 

Mike :D

This is for the track, I wouldnt run ducting on the street... well, maybe out of laziness and not removing them after a track day, but Im looking for examples for the track days.

 

I think I have a pretty good plan to do the job and plan on doing it this weekend.

The only duct setup that I've seen that stays on for street use is what I've got, which isn't very efficient. I ran the duct into the front of the wheel well, then way up high on the fenderwell, then back down next to the strut and out to the strut housing. When you turn the wheel the tire goes in between the sections of ducting in my setup. The problem with a good full race setup is the front tire will knock the ducts off if you have them going straight back on the frame rail like John and Mike said or if you stuck them underneath the frame rail anything like a speed bump or a driveway would probably knock them off, but if you set them up like I did then the air probably loses a lot of velocity by the time it gets to the brakes. I suppose you could limit the steering so that you didn't knock the ducts off, but then you have a 100 ft turning radius.

 

BTW--My brake problems did seem to lessen very slightly after I got the ducts on, so I do think it is doing SOMETHING, just not enough in my personal case.

Ive got a system that bolts to our 280z front air dam. It ducts from the openings on the air dam to am aluminum box that bolts to the fenders in the wheel well, that in turn distributes the air to both sides of the inner rotor. The setup stays together intact 24/7, no problems. Anyone want pics of our setup?

If you want to get fancy you can build boxes, drill 2" diameter holes in the inner fenderwell and run blowers. But, most important, is a can over the rotor that distributes air to both sides of the braking surface. Page 80 in Carroll Smith's Prepare to Win has a drawing of the can I'm talking about.
