Mid America front spoiler ?
Does anyone have the front spoiler with the brake cooling ducts?
If so what do you thank about it and where did you run the hose?
Pics?
I just got mine and will be instaling it this weekend.

I have this set up on my 86. If you are tracking the car, it definitely helps. It has greatly reduced brake fade. I ended up wire tying the tubes to the sway bar and aiming them at the rotors.

They help a lot! They don't make a difference with brake dust. The dust is all over if you have ducts or not.
The kit is okay but if your spoiler is in good condition it would be better to get real hose. And put the ducts in the nose.
Here's how mine is routed:

The duct needs to be much closer to the rotor, the center part. The plastic hose melts but just pull it to extend it out again. Every event mine melts and gets stretched back. I really need to replace it, it lasted good though.

I have them on my car and like them a lot. However I also have the Quantum Motorsports Spindle Ducts that put the air right into the rotor. There is one issue with my set up, the Mid America ducts are 2" hose and the Quantum Spindle Ducts are set up for 3". The way I made it work was the 2" hose fits inside rather than out side the duct inlet.
I have had good luck with mine.

Unless the hose is right up to the rotor it is a wasted effort.
If you are planning on driving the car to the point where you actually need cooling (track), spindle ducts and high temp ducting with a smooth inner wall (for better flow) is the best choice. If you don't want to spend the extra $ Aardwolf and grantar2 are right on... get that hose right up against the center part of the rotors. The best cooling is from air going THROUGH the rotor vanes, air that is just blowing on the rotor face isn't doing much at all. Best case you are only cooling the inner rotor surface while the outer is getting nothing.

That's interesting... how were you testing and with what speed air? Was the difference negligible or none at all? It seems like pretty simple aero principles that air flows better over a smooth surface than one with a bunch of perpendicular edges.

dogfish246 you can do the math easy for hose diameter for CFM.

Yes, thats easy, but does the air actually flow through the holes, and to the brakes? Maybe there will be a high pressure buildup at the inlet and cause minimal air flow to the brakes... I dont know, just wondering. Im probably thinking into it too much...
