JWAT bodywork reinforcement bosses
These bosses prevent the wing from lifting the Spage base plates at speed. M6 bolts hold the Spage base plates and trunk down onto the reinforcement bosses, which is secured to the bodywork underneath with M5 bolts.
Recommended installation method (per side):
Install the Spage base plate onto the trunk
Drill a 6mm hole in the Spage base plate as perpendicular to the surface as possible (location as shown)
Install an M6 nyloc/similar nut into the boss. Note that the nut cavity is on the forward side of the boss
Roughly position the boss on the bodywork (as shown) and refine the location by eyeing the top boss hole through the closed trunk
Mark the locations of the M5 drill holes and install M5 rivnuts
Secure the boss to the rivnuts with M5x16mm screws
Just before you head out onto the track, secure the trunk to the boss with an M6x35mm screw
