Note; only two are drilled for center caps.Magnesium versions of Torq-Thrust "D" and Torq-Thrust wheels were produced in a variety of styles. Sizes ranged from 15 by 4 to 16 by 13 bolt-on for bolt-on wheels, as well as a 15 by 3 1/2 spindle-mount that was often used on Funny Cars. They had either straight or "dog-leg" spokes, the latter being made for race cars with disc brakes, and known as the Torq-Thrust D. Straight-spoked wheels were offered with spokes that were peaked along the center, or rounded. Early magnesium rear wheels are most commonly found with straight spokes, and about equally divided in popularity between peaked and rounded spokes. Although American Racing hasn't made magnesium wheels for decades, and no longer makes the original Torq-Thrust, the company currently produces several modern versions of the aluminum Torq-Thrust wheel. The Torq-Thrust "D" and the newer TTO are the only ones that are one-piece castings. The only vintage racing wheels that American Racing Equipment ever made without casting their name into them were made out of magnesium.
