aero for 2002 focus. Advice please.

[bp944]

I am looking at doing an undertray for my 2002 focus zx3. The can has 292,000 miles on it but is still going along nicely. It does look pretty bad so therefore I plan on modding all I can. I think this weekend I will be putting an under tray on the front and the rear. The middle section seems to be quite clean aerodynamics from when i was under there last. The rear seems to be a giant scoop for the air. Has anyone done this on a zx3? I only saw one when i searched the forum and online but no others. I was just curious what proved most effective for the focus.

I will also be doing the rear wheel wells once all the slush of minnesota disappears. I think snow would just get lodged in the wheel.

Here is what I did:

i just wish we could quantify the gains in the post above...

i'd do a belly pan if i could figure out a good way to attach it.

I never got around to testing my belly pan, but I'd say an air dam is much cheaper, easier and probably just as effective. due to the design on the focus rear suspension, your flow is going to be disrupted no matter what.
