Brake Ducts in STS
Are they legal?

Also, has anyone made some for their car?

yes brake ducts are legal in STS.

fw_pa 08-06-2007 06:54 PM

more specifically...
C. Air ducts may be fitted to the brakes, provided that they extend
in a forward direction only, and that no changes are made in the
body/structure for their use. They may serve no other purpose.

Awesome. Now I just need help getting the ducting to stay pointed at the rotor. I just need to get a friend to fab me a plate, I guess.

Huh, that's cool, for some reason I thought this was a Street Prepared mod. I'll keep this in mind if I jump out of the GS pond.

Do you even need them for autocross? I haven't had a problem even on a big track like beaverun or mid-ohio.

I would think that they would cause more harm than good on an autocross course, because they would add weight. not much weight but weight. And I wouldn't think you need the cooling because you average race is what a minute? in that amount of time your breaks are just starting to warm up let alone over heating.

Yep. Don't really think you need them.

The only possible exception would be if you ran a high speed AX like at Cumberland Airport or at an SCCA Solo2 event on a track. Even then, I doubt seriously that you would notice a difference.

The brake duct allowance was put in place for larger heavy cars that employ a closed type of wheel. Mercedes, BMW and the like where heat gets trapped between the wheel and the rotor.

I would say that adding brake ducts to a focus, SVT or otherwise, is unneccessary.

^^ agreed. But if you must, check eBay for some brake duct hosing. I got a good 5' or so for 40 bucks to replace my worn pipercross hose (which is actually brake ducting hose)

Maybe I just need to upgrade my brakes, haha.
