Nissan altima FRONT undertray/wind diffuser/ Space shuttle?!?!

All the safety stuff was checked. It's held by 3 screws and ducttape. As you can see it makes the air bypass the tire wells and go straight under the car.

AFTER

u have to have some air in

u have to have some air in the wheel ro you'll overheat the brakes. and if your going to put tape on your car for arodynamics, put clear packing tape on. the other looks like duck tape is holding up your front bumper :S

unless you're driving down

unless you're driving down mountains or on a race track, i wouldn't worry about overheating your brakes.

i think it looks good, compaq!

trust me these brakes won't

trust me these brakes won't overheat. Even if they fade they will be still strong. There is still air going in the brake area you just can't see it in the pics.

You can't even see it unless


You can't even see it unless you go under the car. Hopefully it does it's job and makes the air go straight under the car unstead of hitting the tire well. I'm trying to get 40mpg at 65mph. I'm almost there.

got the mpg results. This

got the mpg results. This car is so weird I can't ever get it consistent. Anyway the mpg with the undertrays and the belly+ 2psi in tires is = 34.07mpg

So the 38mpg thing is a fluke. It was going good so good but when I went back up north the guage started to move quick. This is disappointing, you guys get for the city what I get on the freeway.
