This is the 1/8 off road Plastic Rear Wing from Ultimate Racing. It’s intended for both, buggy and truggy. This rear wing provides more rotation in slow corners while improving stability in fast corners.
It’s common for racers to add holes to the back of the wing with hand trimming and tuning. The Ultimate wing has pre-marked locations to allow the opening of the rear dam to allow more wind flow and air to escape during jumping. A grid is positioned and molded into the design to allow the racer to mount squarely and accurately to just about any 1/8th off-road vehicle.
