If you're considering a WRX for anything over 300 I would just try to get an STI. You get so much more for your money...huge Brembo brakes, forged BBS wheels, 6 speed bomb proof trans capable of handling 600whp+ stock, bigger stronger rear diff, axles, driver controlled center diff, bigger turbo, intercooler, better intake mani, etc etc etc. The STI really is just hands down way better in every performance aspect. The 5MT WRX tranny is its weakest part.

intresting. so the sti tranny can take 600whp no problem ? this is stock.
i just was in a 500ish whp capable evo yest not too sure what his boost was set at. never been in a awd car before, it was just a quick 1, 2, touch into third run down a side street. im sure it would be nasty in 4th and 5th on the highway, although it wasnt the throw you in the seat power i was expecting, it didnt break tires loose really.
have you driven any evo's ? if so whats your comparison from an evo to an sti ?
stratton.
