Just pulled off a rim to have a look if the offset was stamped inside and to my surprise they're stamped with 'Mitsubishi' & has the diamonds an all...
I've had them off plenty of times before doing brakes etc but never noticed.
They're OzRacing turismo Gts (i think) 7.5 x 17 +38
Dunno if they were ever optioned with the car - or on another Mitsu, but i always thought they were aftermarket...
I believe those came stock on an evo 6
