Hope this is the right place for this. I didn't see an autocross-specific area to post.
I picked up a 2004 ZX3 back in November. It's a low-optioned, 2.3L Duratec PZEV car. (crank windows, no fog lights, no cruise, etc.) After some research, I felt that it was the most suitable STF car for my needs and should be very competitive. It has one of the best "Engine Displacement to Weight" ratios in the class, which makes me think it has a lot of potential.
I've started purchasing some parts for the build, but most of these won't be installed until the weather improves. (It's -7 F right now.)
For those who don't know, STF allows for "common street mods." So basically bolt-ons, such as: Cold air intake, header, high-flow cat, cat-back exhaust, ecu tuning, coilovers, seats, etc. Wheels and tires are limited to: 7.5" max width wheels and 225 max width tires with a minimum utqg of 140.
I'm open to discussion and/or ideas for the build. I have built a few autocross cars before, but I might need help with a few things specific to the Focus.
