18×8.5″ and 18×10″ Porsche 993 Supercup Magnesium Wheels by Speedline

These 18″ multi-piece Porsche wheels were manufactured by Speedline for use on 993-generation Porsche 911 Supercup 3.8 race cars with center-lock hardware. The lug bores were drilled to accommodate 5×130 applications when Komatsu-san refinished the wheels in preparation for the sale. The wheels measure 8.5″ and 10″ wide and feature magnesium centers, aluminum-alloy barrels, polished lips, and a five-spoke design.

The wheels carry part numbers 993.362.136.80 and 993.362.136.85. The front wheels have an ET53 offset, and the rear wheels have an ET60 offset. “Speedline for Porsche” lettering is etched onto the lips, along with offset and width markings. Center caps are included.
