Engineering Features
Forged Strength
Built from forged 6061-T6 aluminum for increased strength, improved impact resistance, and the structural confidence expected from a real performance wheel.
Reduced Rotational Mass
A lighter wheel package helps sharpen steering response, improve acceleration feel, and reduce unsprung weight for a more composed, connected drive.
BMW M Brake Clearance
The spoke profile and barrel architecture are designed around modern BMW M applications to provide the brake clearance serious street and performance builds require.
Purposeful Offset Strategy
The staggered specification was selected to deliver the flush, planted stance enthusiasts want while maintaining the drivability standards expected from a CarBahn wheel package.
