GA1R OPEN LUG Forgeline Wheels


Perhaps the most advanced wheel that Forgeline have ever made, the fully-forged one-piece monoblock GA1R racing wheel 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.
