5Zigen FN01R-C - The cast version of the forged FN01R, the -C has the exact same styling as the forged version, but comes without the 3 month wait or three times the price. Five spokes arch from the hub circle and land near the edge of the lip for maximum caliper clearance. The silver finish covers the entire wheel and is nice and bright. A cast race wheel, the FN01R-C is not sold with center caps, which must be purchased separately.
