This is my 2001 Focus. I haven't really done anything too fancy in the way of modifications, just a little bit of everything.
As of now, it has the following
Engine:
Focus Central intake system
JBA Cat4ward 50 state legal header
Focus Central high flow cat
Focus Central flex pipe
Bosal cat (flex) back exhaust
Suspension:
Eibach Pro-System suspension kit (Pro-kit springs, Pro-damper shocks/struts)
Kumho Ecsta supra 712 tires
ICE
Alpine 7995 deck
Infinity Kappa something or other front speakers
US Acoustics USX-065 4 channel amp
JBL BP300.1 Amp
Image Dynamics IDQ10 10" Subwoofer
Appearance
APC clear corner lights
Focus Central billet aluminum antenna that used to be black but is now bronze for some reason
10% tint on the back 3 windows (soon to be on the front ones as well)
As of now, it has done a best of 16.9 in the 1/4 mile. That was before the header, cat, and flex, which, strangely enough seems to have hurt the dragstrip performance. Oh well, FWD is a sucky drag platform anyway. That and I suck at launching it. :)
I have some cam gears, a short shifter, and a UDP in my to do pile, and I think I might be picking up some cams too. I'm also planning on upgrading the front stage of the sound system with a component setup, and getting some tint on the front windows to match that on the back (and to protect my precious car audio from the evil people in the world ;)).
