About Forgeline
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, Forgeline has applied their 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, Forgeline has 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, Forgeline 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! Forgeline 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 Forgeline's hands-on company owner and their entire team of employees ensure that every Forgeline customer is confidently investing in quality, strength, durability, and performance with every purchase.
