XA.4 - ROLL-OVER BAR COMPETITION REINFORCEMENT KIT
This kit is designed to provide additional bracing to the roll-over bar for competition use, and allow the
fitment of the 6-point competition seat belt harness (see sub-section XA.2). The standard 3-point inertia reel
seat belts cannot be used with this kit. Note that the roll bar fairing and audio speaker panels must be removed
or modified, and that some drilling of the chassis is required to fit the forward bracing strut.

Fitting Procedure
1. If fitted, remove the following:
Roll bar fairing and rear window;
Both audio speaker panels;
Both inertia reel lap and diagonal seat belts;
Passenger footrest
2. Remove the end spigots from the 'A' frame harness bar, and fit the 'A' frame into position. Locate each
bottom end of the frame with a hex. head bolt and washer to the existing inertia reel fixing point.
3. Insert the end spigots into each end of the harness bar, and fit the fixing bolts to the roll hoop and harness
bar. Tighten the 'A' frame bottom fixings to 33 Nm, the harness bar end spigots to roll hoop to 45 Nm, and
the harness bar to end spigot through bolts to 22 Nm.
4. Remove the nut and washer from the passenger side front lower wishbone rearmost pivot bolt, and fit the
bracing strut corner plate over the end of the pivot bolt into the corner of the footwell. Mark the four fixing
hole positions in the corner bracket against the chassis before removing the bracket and drilling the
marked holes 9 mm diameter.
5. For access to the corner plate fixings inside the chassis side rail, it is necessary to cut an access aperture
in the underside of the chassis rail. With a centre marked as shown in the diagram, use a hole cutter or
similar tool to cut a 35mm diameter hole and remove the sharp edge.
