So after an hour sifting through the web, ive found at least an answer as to the size of my original wheels.
5x100 57.1mm center bore et39(offset)
does anyone have a lost of other vehicles that came from the factory with these same specs? I feel like it would be easier to buy a set of oem wheels from another car with tires already mounted (off craigslist) than it would be to magically pull $300 out of my rear.
