The car handles more steadily. I feel the air deflected and the car drives straight in the road. I feel more in control with the air dam.
Not yet, but that's the plan. But I think that mine (not yet installed after two years) was made on the same day that Mavaholic's was.
Unless you are actually road racing your Mav, the ducts are only for looks and on a street car they can cause brake issues. On rainy days they send water onto the brakes. This can cause stopping issues. They are less effecient in the area of air defection as there is less frontal space. In my younger years I ran a ducted spoiler on a Datsun 510 that I autocrossed and drove on the street. It got down right scary in the rain and with the non-ducted spoiler I got better gas mileage and more air to cool the engine as it forced the flow up to the radiator and reduced turbulance under the car. I have one on my Maverick. I did it more for looks then function.
I did this the week before going to Road America. I had to make it fit, the right side(left side of picture) was about 3/8'' too short, so I cut along the edge by where it mounts to the car, expanded it toward the car where it needed to go and re-matted the whole darn thing due to it was a bit inconsistant in it's thickness. The brake ducts and tubing were from a local circle track store, and I got the beer at the liquor store. It took a little bit to decide where I wanted to put them, after that I just made sure that there was enough tubing and room for them with the wheels turned. I mounted the tubes to the dust sheilds on the spindles after making the holes in them bigger to fit the tubes on them. Zip ties, zip ties, zip ties!!!! Also, I didn't trust the 'glass to hold up to high speeds, so I installed some turn buckles from the hardware store which is right next to the beer store. Differences I noticed were a little cooler on track temps, and it took a little longer to get the brakes to heat up, but once heated up, I had very little if any brake fading near the end of any of my sessions(sessions are about 20-30 min long).
