Sean H. - your brake ducts..question (archive)

- looks like the install is to basically cut the lower lip off the chin spoiler, then fit the ducts in. Other than the cut for the duct pick up and the related mounting tab, is there any other cutting? Also, I know you had a mechanic do it (body shop?)...can you estimate how "exact" the cutting has to be? Do you know what tool was used to make the cut? Is there an outter lip on the duct that allows for minor inperfections? Trying to get a feel if this is something I would like to tackle or not.

- Can you describe where the ducts channel the air? Is it to the front of the rotor (leading edge)? Or do they somehow get air near/under the center hat of the rotor? What is your opinion on the "volume" of air they might be able to direct? Bascially, I'm interested in what you think their cooling effectiveness might be...

I'm considering the ducts as a tool to help control brake temps during lapping days with my local club. Cosmetically, they look great.. Wondering if they are effective as well.

Thanks!
