Description
The Ultragram pairs a seven-spoke layout with flow-formed construction and knurled bead seats. Its open design gives the wheel a purposeful motorsport appearance.
This listing specifies a 17x8 wheel, a +38mm offset, a 5x100 bolt pattern, and Titanium Metallic finish.
Engineering and design
Flow forming applies pressure to the wheel barrel after casting to develop the finished barrel structure. It is a different manufacturing process from producing a fully forged wheel.
Knurled bead seats add texture at the tire-to-wheel interface to help resist tire movement relative to the wheel during demanding acceleration or braking.

Fitment considerations
Confirm the vehicle hub diameter, correct lug hardware and seating type, brake clearance, tire sizing, and suspension and fender clearance before ordering. Bolt pattern alone does not establish fitment. Hub rings may be needed when the wheel bore is larger than the vehicle hub.
Wheel width and offset work together to determine inner and outer clearance. Check the intended tire and suspension setup as part of the complete fitment.
