Why 4x100 Matters for Tuner Builds
The 4x100 pattern is a staple on lightweight compacts, classic hatchbacks, and many import tuner platforms, which makes it a natural home for Spec-1's racing-inspired styling. Spec-1 describes its range as racing and tuner wheels built for performance, handling, and style, and the 4x100 group leans into that purpose with concave faces, straight-spoke designs, and undercut detailing. Because so many of these fitments are dual-drilled 4x100/4x114.3, you get added flexibility if you run more than one car or plan a platform swap.
Models & Finishes Offered
The 4x100 group is deep. Multi-finish workhorses like the SP-51, SP-52, SP-53, SP-54, SP-56 and SP-68 come in Gloss Black, Gloss Black & Machined, and Gloss Black & Red Machined. The SP-69 offers the widest finish menu, including Gloss Black & Milled and several undercut treatments, while the SP-73 adds Milled & Undercut and Red Machined & Undercut variations. For color, the SP-67 carries Gloss Bronze, the SPT-33 and SPT-31 offer Matte Bronze & Black Lip and Gloss Black & Red Line, and the SPT-35 stands out with Gold & Machined Lip. The SP-78 even offers All White. Explore by color through the black, red, bronze and blue pages. Each of these is a monoblock wheel.

Fitment Coverage
Within the 4x100 group, diameters run from 14, 15 and 16 inch fitments up through 17, 18 and 20 inch options, with select 19 inch sizes on models like the SP-69 and SPT-31. Smaller setups such as the SP-76 (14"–16") and SP-77 (16") suit lightweight builds, while 17- and 18-inch fitments dominate the lineup. Many designs are dual-drilled 4x100/4x114.3, and several models also extend across 5x100, 5x105, 5x108, 5x110, 5x112 and 5x114.3 in their five-lug versions. Shop by diameter via the 16", 17", 18", 19" and 20" pages.
How to Choose
Start by confirming your hub bolt pattern is 4x100 (or 4x114.3 if you want a dual-drilled fit), then match diameter and width to your tire and clearance goals. Smaller, lighter setups like the SP-76 favor autocross and stock-suspension cars, while 17x8.5 widths add stance and grip. Pick offset carefully against your fender and suspension; +42 is common across the lineup, with lower numbers like +30 pushing the face outward. Finally, choose a finish that suits the build — subtle machined faces, bold red-line accents, or warmer bronze and gold tones.
