While I work on my car's diet ('97 993), I am also looking at how to put in some brake cooling ducting to the center of the rotors up front. I did a search but was not able to find anyone who had run some ducting from the front (not necessarily through he brake duct hole) into the trunk area and then directly into the rotor.

I cannot put ducting in the fender well area coming through the front fender liners since the wheel/tires will simply wear the ducting out each event when the wheels are turned.

So if anyone has seen a solution that can run ducting perpendicular to the rotor and then out the front to get the air flow I would love to hear/see it.

I was thinking that some ducting could be put into the lower front splitter area (below the fog lights/brake duct holes) running it through the trunk wall in front. Then running it through the trunk wall directly to the rotor thus avoiding any wheel clearance issues with the ducting when turning. Thoughts?

Thanks!

 

Kary,

This installation from Robin's page doesn't go thru the trunk area, but it doesn't look like the tires would rub.

Take care,

 

I've thought about making something like this out of fiberglass. It seemed to me that the clearance between the wheel and inner wheel well would be small, and that this might be simpler and less costly than using the front air ducts. Also, I don't think you could really center the air stream onto the center like this example. I spoke with the racers group once, and they said that they run as much ducting to the brakes as they can, and that where the air stream lands on the rotor isn't that important. I think he said they even duct air to the caliper.

 

Kary,

The mod you discribe is exactly what I have seen on some race cars at a shop I go to. I will be down there in the next couple of weeks and try to get some pics if you want. Like you said it is just a couple of holes and the air flow is quite direct with no pinched ducting.

 

Keith, I would appreciate it if you could get some pics of those cars you mentioned. I saw a few myself before but did not have any pics.

Thank you for the help!

Kim, that is an idea I had not considered. Though I have changed my lights with teh Catz system so taking them in and out is not as simple as it once was ;-(

 

No problem. My car is there now for the oil cooler install. When I go get it I will get some pics.
