A 17” Te37xt would not be possible,
While the overall diameter of the wheel is 18”, the face itself is smaller within the step lip design. Tolerance is tight as is. I too wanted the 17”, but Rays would not produce a 17” XT.
Technically that's backwards. A step lip (standard mount) makes for more brake rotor clearance since the drop center is in front of the face opposed to being on the back side of the wheel. When the drop is in the back the barrel is smaller. For reference every Method 17" wheel is standard mount. Some show the step some don't but by being standard mount it allows the inside barrel to be larger to accommodate the rotor size. Velgen forged only does reverse drop and that's why they only offer 18" and larger.
So I think they could do it but may just be choosing not to.
