SP-55

Spec-1 SP-55: A Clean Monoblock Wheel for Daily and Show Builds

The Spec-1 SP-55 is a monoblock wheel with a split five-spoke face, the kind of open, angular design that suits compact and mid-size cars looking for a sharper stance without going loud. It sits alongside the rest of the Spec-1 lineup as a value-focused street wheel that works well on tuner and daily setups alike.

Sizes and Fitments Stocked

The SP-55 comes in 17, 18 and 20 inch diameters, in widths of 7.5, 8 and 8.5, with offsets of +38 and +42. Bolt patterns cover a wide spread: 4x100, 5x100, 5x105, 5x108, 5x110, 5x112 and 5x114.3, so it works on a large range of imports and European chassis.

Concrete examples in stock include the 17x7.5 +42 in 4x100/4x114.3 Gloss Black & Machined and the 18x8 +38 Gloss Black for a plainer look. Five-lug shoppers can grab the 18x8 +38 5x100/5x114.3 Gloss Black & Machined or the 17x7.5 +42 in the Red Machined finish. Browse more Spec-1 5x100, 5x114.3 and 4x100 options if you need to match an existing pattern.

Finishes

Three finishes are stocked: Gloss Black, Gloss Black & Machined, and Gloss Black & Red Machined. The machined faces catch light on the spokes, while the red-accented version adds contrast. See it in context on the black Spec-1 and red Spec-1 pages.

Price and Who It Suits

The SP-55 runs from $133 to $451 per wheel depending on size, pattern and finish. It suits budget-minded builds that still want a machined-face look, and it clears typical tuner and compact fitments across the offsets listed above. Financing is available through Affirm, Katapult, Klarna, PayPal Credit and Snap Finance at checkout.

How It Compares in the Range

If the SP-55 face isn't quite right, the SP-54 and SP-56 are close siblings with different spoke patterns, the SP-51 leans more traditional, and the SP-60 and SP-64 offer alternate looks in the same family.
