Product Description

Series G GSR05 Forged Wheel: Built for American Muscle

The Series G GSR05 is a 2-piece forged wheel made for muscle cars, pro-touring builds, and classic trucks. It pairs a clean, classic spoke design with the signature Series G step lip, and every set is built to order for your car, so you get a custom wheel that actually fits instead of one that almost does.

Each GSR05 starts as forged 6061-T6 aluminum and is CNC machined, assembled, welded, and finished in-house at our Terre Haute, Indiana facility. If you're looking for an American made wheel for your Camaro, Chevelle, Mustang, or C10, this is the one built to carry the look and handle the power.

Why Choose the GSR05?

• Forged strength, less weight. Forged 6061-T6 aluminum centers and rim sections (never flow-formed or cast) give the GSR05 an excellent strength-to-weight ratio, so your muscle car accelerates, brakes, and turns with less unsprung weight.
• Built to your exact fitment. Backspacing is set in 1/8" increments, with custom lug patterns and four caliper clearance options. Whether you're running Detroit Speed mini-tubs, a QA1 suspension, or big brakes, we build the GSR05 around your setup.
• No upcharge for fitment. Your price is set by wheel size. Backspacing and caliper clearance never change it, so you can get the fitment right without paying extra for it.
• Your finish, your way. Choose from 18 UV-resistant powder coat finishes, including two-tone combinations, all applied in-house over an OE-level pre-treatment for a finish that lasts.
• Engineered for the track. Weight-relieved spokes and finite element analysis help the GSR05 exceed SAE standards, so this aftermarket wheel is as ready for autocross as it is for the street.

A Classic Car Wheel With Modern Engineering

The GSR05 gives a vintage build the look of a period-correct forged rim with the strength and fitment of a modern performance wheel. Fill out wide rear tubs, clear a big brake kit, or dial in the perfect stance on a restomod. Because every GSR05 is made to order, the wheel is built to fit your car, not the other way around.
