The TE37 Saga S-Plus is the modern high-strength evolution of the most iconic forged wheel ever made, and the A.S.T. (Advanced Surface Technology) Brushed finish is the most premium way to own one. Rather than paint, the A.S.T. process leaves a raw, hand-brushed machined-aluminum face with a deep directional grain that catches light differently from every angle. It is one of the most labor-intensive finishes RAYS offers, and it sits at the very top of the TE37 Saga S-Plus range.
This is a staggered, forged one-piece set built specifically for the G8X-generation BMW M cars: 20x10 +15 up front and 20x11 +15 in the rear, on a 5x112 bolt pattern with a 66.6mm hub bore. The wider rear gives these chassis proper stance and tire while keeping the offset conservative enough to clear the factory big brakes. Each wheel is forged in Japan and TPMS compatible.
Note on the A.S.T. Brushed finish: this is a raw brushed-aluminum surface, not a painted or clear-heavy finish. It rewards regular care and wiping down, and like all bare machined finishes it should be kept clean and protected to preserve the look. If you want a maintenance-free finish, consider a painted S-Plus option instead.
