Spec-1 SP-8: Monoblock Street Wheel for 5x114.3 and 5x115 Builds
The Spec-1 SP-8 is a monoblock wheel with a clean split-spoke face and a machined lip contrast that reads well on sedans, coupes and crossovers. Its single-piece monoblock build keeps the design straightforward and the profile aggressive, aimed at street cars that want a finished look without stepping into boutique money. It sits within the wider Spec-1 lineup as one of the brand's daily-driver-friendly designs.
Sizes and fitments stocked
The SP-8 comes in 19, 20 and 22-inch diameters, in 9 and 9.5 widths. Offsets run +15, +32, +35 and +38, so there's room to run flush or tuck a little depending on the build. Bolt patterns cover 5x114.3, 5x115 and a blank 5x that can be drilled to spec.
Concrete examples in stock include the 22x9 +32 in 5x114.3 for a plus-sized fitment, the 22x9 +15 in 5x115 for a deeper, more aggressive stance, the 20x9 +35 in 5x114.3 as a balanced 20-inch setup, and the 19x9.5 +38 blank 5x for cars needing a custom bolt pattern.

Finish
The SP-8 is offered in Gloss Black & Machined, where the machined face and lip cut through the black spokes for depth. Browse more black Spec-1 wheels if you want to compare the look across the range.
Price and who it suits
SP-8 pricing runs from about $253 to $460 per wheel depending on size and fitment. It suits owners who want a machined-face monoblock wheel on a real-world budget across 19 to 22-inch fitments. If you'd rather compare faces, the SP-51 and SP-52 offer different spoke patterns, the SP-57 and SP-60 carry alternate mesh and multi-spoke designs, and the SP-68 gives you another take within the same family.
