here's what i build over the weekend... the final result is not to extreme as it only a bit lower than the front dams, owning to the size of the material available... than again, i could always enlarge them later.
i cut up two 50CD-r spindle lids and unroled them, than i used a perforator to make a series of clean holes in them for the screws (a couple more than needed just in case)
next a gave the back a coat of black paint. since theyre transparent this gives the front a nice gloss finish and the paint can't get sandblasted off at the front (wich happened on my previous car) finally i used some small self tapping wood screws to secure them to the wheel well liner.
here's some pictures:

the last picture shows they might not do all that much, as the car already has some small dams at the front of the bumper... still some air that might hit the suspention and be deflected above it now will be forced below and around it. also the perspective of the picture makes them look smaller then they actually are
i'll see what they are like to drive with in the next few days.
