    has anybody come up with a decent looking air dam for the 3rd gen escort. I made one out of garden edging with a belly pan directly connected to it for my 1993 wagn nd it was extremely effective with a blocked upper grill, sealed front end gaps, and all gaps sealed around the radiator so all air getting past the nose would go through the radiator. Got near 48 MPG with it, quieter interior and much better high speed stability.

    My old sedan. Air dam and splitter. Splitter is made of sealed 1/2in plywood. Dam was made of 3mm thick ABS sheets from amazon. Biggest hurdle was sealing the 2 together. Eventually used black duct tape with rubber spray over the tape. The lights and hood were sealed with adhesive foam strips.

    I gained 5 mpg without changing driving habits during the cold Alaskan winter. In the summer with very conservative driving I managed 1 tank over 500 miles.

    If I could do it all over again I would use nut rivets on the bumper to allow easy removal of the dam and to prevent stripping the threads out of the bumper plastic. I also hit all kinds of things with the splitter and the car was stock ride height.

    I plan on doing something similar to my current Zx2

    I am always amazed at how much the car manufacturer's leave on the table in terms of aerodynamic improvements. On a mass produced vehicle like the Escort probably a few days of aero testing and about $10 to 15 dollars worth of additional plastic on the front end of a vehicle could result in 20 to 30% improvements in highway fuel mileage and improved high way safety. The effects of some basic improvements are amazing. The late 70's boxy sedans by audi have lower drag than most cars today...just by applying some basic improvements.

    I my 93 wagon I used the bumper as the splitter ( like older BMW's) to increase downforce. everything above the bumper was sealed so a pressure point would develop on top of the bumper from the air trapped in front of the grill and headlights.

    The marketing and accounting departments seem to run car companies, not the engineering department.

    The marketing department can't be very good when they miss an opportunity to be able to market an entry level car with 20 to 30% better fuel economy than the competition for almost no additional cost. That level of stupidity is what I can't believe is allowed to happen. Nearly all of the recent aero improvements that have been made on vehicles were all known by the late 1960's and many by the 1950's. Ex. The front air dams used on most newer vehicles that is higher in the middle and lower on the sides was discovered to be more efficient by Fiat around 1969......It took 50 years for the car companies to use this concept.

    I've been looking at the air dams off the mid 90s Chevy s-10 pick up or Ford ranger. They may work since they are flat across the top as are the bottom lips of the Escort bumpers, IIRC. New they can be had for as little as $15.00

    I've been looking for a front air splitter solution for a while now. From what I've read apparently a front air splitter for an early Integra will fit with minimal modifications.

    I've been thinking about getting back to putting in the time to get the rear wing I took off a Kia Soul to fit. I need shorten the width meaning I need to cut out an inch and a half and reglass it. One of the reasons I chose that rear wing was because the mount posts are angled to fit the rear hatch of the Soul and are pretty close in angle to the Escort wagon rear hatch.

    As far as a front splitter my requirements are that it be flexible since the wagon is so low it'll scrape going up or backing out of driveways. The 3rd gens have a small factory air dam mounted below the radiator.
