Ultra 4x100 wheels cover the compact-car and small-import fitment side of the Ultra lineup, built around the 4-lug, 100mm pattern used by many lightweight commuter and enthusiast platforms. Within this pattern the standout is the 403S Slalom, an approachable multi-fit design offered in a clean Silver w/ Clear Coat finish. Ultra also stocks the matching hardware and centering parts you need to mount a 4x100 setup correctly.

Why 4x100 Ultra Wheels Matter
The 4x100 pattern is one of the most common small-car bolt configurations, and getting the finish, diameter and centering right is what separates a factory-looking install from a rattly one. Ultra's approach here is straightforward: a monoblock (single-piece cast) construction on the 403S Slalom that keeps weight and cost reasonable while holding up to daily driving. Because a single wheel model can span several bolt patterns, the 4x100 drilling shares its styling with a broader family of Ultra fitments — so you get a proven design rather than a one-off.
Which Models & Finishes Are Offered
The 403S Slalom is the 4x100 wheel to know, available in Silver w/ Clear Coat across 15", 16", 17" and 18" diameters. If you prefer a darker or different look, the Slalom family also appears in other drillings and finishes worth comparing — the 403BU Slalom in Gloss Black w/Clear Coat, the 403GNU Slalom in Gloss Gun Metal, and the 403SU Slalom in a silver clear-coat. For finished builds, browse Black Ultra wheels, Silver Ultra wheels and Gray Ultra wheels to match your car's palette.
To complete a proper install, Ultra also offers a 4x100 Hubcentric Ring and matching center Cap options, so the wheel seats cleanly on the hub and finishes with the right logo.
Fitment Coverage
Within 4x100, the 403S Slalom is built in 15- through 18-inch sizes — see the full 15" Ultra wheels, 16" Ultra wheels, 17" Ultra wheels and 18" Ultra wheels pages to zero in on a diameter. If your car actually runs a different small-import pattern, related Ultra options live on the 5x100, 5x108, 5x110, 5x112 and 5x114.3 pages. Always confirm your exact bolt pattern before ordering, since a 4-lug wheel will not cross to a 5-lug hub.
How to Choose
Start with your verified bolt pattern and hub bore, then pick a diameter that clears your brakes and matches your tire plan. On the 403S Slalom, the Silver w/ Clear Coat finish is easy to keep clean and pairs well with most factory colors. Add the correct Hubcentric Ring if your hub bore is larger than the wheel's, and grab a Cap to finish the center. Every order ships free, and financing is available through Affirm.
