Crow ooooooooooh S2000! I lusted after that car for a long time. I finally tried one on and my legs are just too long. With my feet on the pedals and the seat all the way back, my knees were wedged against the steering wheel and I couldn't steer. So I never even drove it. But they are freaking nice cars.
Just about everybody on the WRX forums agrees with you about the WRX tires. I'm wearing the stockers out as soon as possible.
I've heard people talk about that bang when shifting. Apparently it's one of the driveline components (I forgot which, there are a lot of them) flexing its mounts and banging into the underbody. I have not heard it, maybe I'm not shifting hard enough.
Supposedly it can be cured by using the STI tranny mount kit upgrade.
The Carbon Fauxbre is an option thank God. Mine just has black plastic.
I have never run an autocross but my dad did for a long time. I have been doing some karting but I'm really too big for those things. So I joined SCCA and am going to run Solo 2 in the SF region. SF region is now also offering rallycross events which is basically Solo 2 on dirt, and I am going to try that too.
