It's 4AM, is this Crazytalk or Revolutionary?
....like stated...it's 4AM, my contacts are drying up, the computer screen is all fuzzy, I'm ridiculously tired but I thought of an idea. This is for the T/A guys. is there a way to make our fender vents functional? If I were to cut out holes from the rear of the fender well, creating an air tunnel leading out the fender vents,, would this relieve brake heat or just make a big mess when dirt kicks up? would this cause drag? is there any way to make these things functional? ...IDEAS ANYONE?
EDIT: mods iuno if this thread applies for this section. feel free to relocate it like LCAs.

Its possible. I know a few third gen owners have done it.
And in order to keep the dirt out, you put a small screen in.

bump on this.... i know in NASCAR they do this by using fans that draw the air out.. does anyone have an ideas to test out the thermo energy being released when braking,, and if it would be helpful to tie a pipe leading the heat from the rotor veins out the side vents. maybe it'll reduce the amount of brake dust =]

the air ducting usually brings air to the rotor, not away.

i'm planning on building brake ducts as well. connecting from the air deflector. ... i'm just seeing if there's any benefit to making the fender vents functional....

i dont see the rear opening helping the brakes in any way whatsoever. But they could eliminate a high pressure area behind the tire, if there is one.

I've never seen a road racer do that if that tells you anything. Usually vents like that are used to vent air out of the engine compartment.

Yea, that's what I was thinking. If you wanna vent anything with those fender vents, hot, high pressure engine bay air would be your best bet. Not sure how easily you could build it though.

Maybe some sort of hoses or something to get the hot air from the engine bay to there i dont know

some of the later model gm's have sensors to read the rotors temp. you could also use an IR thermometer.

Nope. Pickaxe. Makes great speed holes.

good for cooling brake rotors, no, good for relieving high pressure build up in the fender area, yes. Alot fo people talk about using ducts and what not for braking, but thay are only functional if your brakes are built to take it, or for the duty. Heating up brakes and then rapidly cooling them is going to cause warpage unless you use High performance rotors, not to mention, As my racing teachers told me, you want your brakes to stay hot (not too hot to cause fad, but hot enough to grip).
In 1967, there was a battle between Holmann & Moody, and Carroll Shelby To win Le Mans with the GT40 Mk IV. One of the things they didnt agree on was where the front rotor cooling air ducts went. H&M put them on the front Nose, Shelby put them on the hood because he felt too much air to the rotors would warp them after the Mulsanne Striaight...and he was right. Sometime during the night Mario Andretti came in to have his pads replace. He went out, and under the dunlop brige right after coming out of the pits, his brakes locked up, not only crashing himself but several other GT40's as well. The culprit, warped rotors due to excessive heating and cooling, Shelby went on to Win Le Mans by 5 laps over the second place car.
Now not to say you'll get your rotors as hot as them, but if the company felt they were necessary to keep the rotors operationing optimumly, I think they would of been added. So unless your doing Road Racing, or you really like going through pads, no need for brake ducting. What would be nice is to relieve the pressure under your fender. If you look on some high end sports cars, they have louvers over the fenders to relieve that pressure, and to produce downforce. Once again, your car is not a full on race car, so dont expect ot be able to go around corners 10mph faster, it just helps a little.

Not trying to bust balls, but Carroll Smith doesn't believe in warped rotors and is quoted as saying he's never seen one:

Jam, you should probably read that white paper.

Ok, he was part of Shelby's Team, not H&M, H&M was the one who experience d the problems. H&M was also the decider in which way the rear body work should be hinged, and anybody who has read the story aout the 1967 Le Mans race knows what happened....
