This is an optional Hot Bodies V2 Wing Mount, adding an additional 10mm over the standard mount (HBS1144114). Intended for use with the D8 series of nitro buggies.
This one-piece, lightweight wing mount is approximately half the weight of the standard wing mount assembly and is 10mm taller than the standard version to allow you to fine tune the aero balance of your car.
Used by Ty Tessmann to win the IFMAR 1/8th Off-Road World Championship 2014.
Note: Hot Bodies also offers this V2 wing mount in standard height (HBS114414)
