You can talk all you want about enthusiast sites and what people run and how its so easy to boost an RS...
Its not easy. They do have tranny problems. A turbo RS will get smoked by a WRX with MBC & exhaust. A turbo RS has nowhere near the potential of a WRX or DSM without tons and tons of cash, patience, tuning, and a garage, because the car wont be daily driven.
Drive an RS. They're slow. If an intake and exhaust shave a second off the 1/4, then they go from 17sec cars to 16sec cars. They are slow, and hard to make quick. AWD and good looks is all its got going for it...
