Perhaps the most advanced wheel that we have ever made, the fully-forged one-piece monoblock GA1R delivers a trifecta of greatness - strength, stiffness, and lightweight performance - thanks to 6061-T6 monoblock forgings, I-beamed spokes, and Forgeline engineering. Now for serious racers who are looking for the ultimate in lightweight performance, the deal just got even sweeter with the new GA1R Open Lug Version.

Made from the same forgings and shared design as the normal GA1R, the Open Lug Version has even more material machined from the center area for additional weight reduction and improved access to the lugs as well as the omission of the center cap. Depending on size and offset, these changes can save an additional pound of mass from each wheel!

The GA1R is designed for racing. It is engineered with a 2100 lb. street-tire load rating (per wheel) to ensure strength and integrity, even when subjected to the massive loads encountered on the stickiest race tires.

The GA1R is produced using our traditional forging method from 6061-T6 aluminum. It is currently available in 18, 19, and 20-inch sizes with a range of widths and offsets. And just like any Forgeline wheel, the GA1R is available with fully customizable finish options.



Note: This version will NOT accept a center cap. Recommended for track use only.

Forgeline Motorsports manufactures the world's finest custom-made high-performance lightweight forged aluminum street and racing wheels for the most discerning enthusiasts and the most demanding applications.

For over 20 years, we have applied our racing experience and passion for motorsports toward designing and building wheels that can withstand the extreme demands of sports car racing. With an unwavering commitment to strength and safety, we have earned a spot on some of the world's fastest race cars including those in Grand-Am, American LeMans, SCCA Pro Racing, and virtually every amateur racing series in America.

Every Forgeline wheel is engineered using computer-simulated finite element analysis and tested beyond SAE standards using real-world load variables to ensure strength, safety, and performance. Innovative features like I-beamed spokes, hidden titanium ARP fasteners, meticulously-engineered centers, and complex manufacturing techniques (like those found in our flagship three-piece competition wheel, the GA3R) ensure that Forgeline wheels are strong, fast, and stunning.

Forgeline wheels are machined from heat-treated 6061-T6 aluminum that is forged on a 6000-ton hydraulic press. This forging process aligns the grain structure, reduces porosity, and increases uniformity in the material, creating the highest strength-to-weight ratios and the most consistent quality. On average, our forgings are 40% stronger than cast aluminum.

Forgeline's own in-house manufacturing and engineering capabilities also provide unmatched flexibility when it comes to vehicle fitments, wheel sizing, and custom finish options. Whether you need a wheel that is specially-built to accommodate your unique suspension and brake package, or you just want a custom color combination to express your own individual personality, Forgeline can get it done! We can even build completely original one-off wheel designs for prototypes, show cars, and creative enthusiasts who wish to have a truly original wheel.

And Forgeline's legendary quality and customer service is unmatched. The experience, dedication, and personal involvement of our hands-on company owner and our entire team of employees ensure that every Forgeline customer is confidently investing in quality, strength, durability, and performance with every purchase.
