Quoting fuel:
the reason why the first gen S40/V40 rims are a perfect fit, is because that car was developed in conjunction with the Mitsubishi Carisma, which itself is a modified version of the Lancer/Mirage platform. In Europe, the S40/V40 can be equipped with the 4G93 1.8L Mitsubishi GDI engine. You can bolt Evo1/2/3 front suspension right into the S40/V40, however out back it is slightly different from the Lancer/Mirage.
No they fit and look great because both cars got they're styling cues from a brick /ubbthreads/images/graemlins/tongue.gif
