"Worth every penny"

I've owned many sets of wheels over the years, but these are by far the best. The craftsmanship is second to none. The team at Forgeline was incredibly helpful throughout the ordering process.

"Great track wheels"

Perfect for my weekend track car. Light, strong, and look amazing. The custom offset options made getting the perfect fitment easy. Will definitely be ordering another set for my daily driver.

Custom Fitments

CUSTOM FITMENTS,
TAILORED TO YOUR CAR

All Forgeline wheels are custom made-to-order. That means we engineer and build every set of wheels from scratch one at a time to match your vehicle specifications and intended application. From custom size, lug pattern, and backspace/offset, we can create the perfect fitment for your build.

Custom Finishes

CUSTOM FINISHES
TO FIT YOUR STYLE

We finish every wheel by hand. It starts with the labor-intensive hand-grinding, sanding, and inspection process. From there, we hand-apply a high-quality powder coat that's more consistent and durable than any mass-produced alternatives. Choose virtually any color for your wheels.

Made in USA

CUSTOM WHEELS,
MADE IN THE U.S.A.

We manufacture every Forgeline wheel at home in Dayton, Ohio. Down to the raw aluminum forgings, we source the best materials and parts from trusted companies that we believe make the best products. Why? So you can be confident knowing that you're getting the highest quality wheels possible.
