The Team Losi Racing 8IGHT 4.0 Gen II Wing Mount is included with the 8IGHT 4.0 Tuning Kit (TLR248000). This wing mount allows for the polycarbonate or the standard plastic wing to be used by allowing 5-40 screws, aluminum support washers and nuts to secure it to the mount, but as an added feature you can install the included machined post to continue to use the body clip method for attaching the wing to the mount.
