Spec-1 SP-78: Monoblock Wheels for Compact and Sport Builds

The Spec-1 SP-78 is a monoblock wheel built for daily drivers, hot hatches and sport compacts running smaller diameters. Its clean, multi-spoke face suits cars that want a tidy modern look without going aggressive, and the size range keeps it practical for street setups. It sits within the wider Spec-1 wheel lineup as one of the more street-focused options.

Sizes and Fitments in Stock

The SP-78 comes in 16, 17 and 18-inch diameters, in 7.5 and 8 inch widths, with +30 and +35 offsets. Bolt patterns cover 4x100, 5x100, 5x112 and 5x114.3, so it works on a broad spread of imports and compacts.

Concrete examples in stock include the 16x7.5 +30 in Gloss Black, the mid-range 17x7.5 +35, and the larger 18x8 +35 for a fuller stance. You can browse by fitment through our Spec-1 4x100, 5x100, 5x112 and 5x114.3 pages.

Finishes

The SP-78 is offered in Gloss Black, Gloss Black & Milled and All White. The milled variant, such as the 16x7.5 +30 Gloss Black & Milled, adds machined highlights on the spokes. If you're comparing dark options across the range, see all black Spec-1 wheels.

Price and Who It Suits

The SP-78 runs from $256 to $365 depending on size and finish, keeping it a value pick for compacts and daily builds. It suits owners who want a clean monoblock look on a sensible budget rather than a track-first setup.

If the SP-78 isn't quite the face you want, the SP-68 and SP-67 sit close in the range with different spoke patterns, while the SP-51 and SP-52 offer alternate mesh and spoke designs. The SP-60 is another street-oriented option worth a look.
