5x100 is the small-car Subaru and VW pattern. You will find it on Subaru and older Volkswagen Golf and Jetta. We stock 1,419 wheels drilled 5x100.
Measuring is simple: count the studs, then measure the diameter of the circle they sit on. Five studs are measured from the far edge of one hole to the center of the one two holes away; six or eight studs across opposite centers. Ordering the wrong pattern is the most common fitment mistake — if your measurement falls between two patterns, confirm with the vehicle's spec sheet first.
