whats the difference between STI and WRX versions? I never know, except I think the STI has better spoiler and bonnet scope, more BHP too?
Spoiler choices are options, but yes, in general a WRX will have a low spoiler and an STI will have a high one. Unless they don't. STIs have more power and torque, better suspension and better brakes. Yes, the scoops a bit bigger too. IIRC they have slightly wider track, and usually have bigger wheels. Generally a WRX is the car you buy, then regret that you didn't buy an STI.
