XA.3 - COMPETITION/COMPETITION STYLE SEATS & 6-POINT COMPETITION HARNESS
The Competition Seat is made by Corbeau specifically for the Elise for race track use, and features
prominent shoulder 'wings' and raised side bolsters designed to provide maximum lateral support in racing
conditions. Four point multi-position mounting brackets connect the seat to new seat mounting rails which use
the original chassis fixing holes. A wide range of seat position, height and tilt is available, but once chosen is
not readily adjustable. Note that the seat needs to be angled towards the car centreline (as does the standard
seat) and uses different fixing holes in the inboard and outboard rails. The seat and mounting rails are de-
signed for use with the 6-Point Competition Seat Belt Harness, in conjunction with the Roll Over Bar Reinforce-
ment Kit.
Only one Competition seat can be fitted, as a similar passenger seat would result in a clash between the
seat back 'wings'. However, a Competition Style passenger seat is available, which uses the standard seat
shell, trimmed to match the Competition seat and modified to allow fitment of the competition seat belt har-
ness.
Alternatively, a pair of Competition Style seats may be fitted using either the standard 3-point inertia reel
belts, or, in conjunction with the roll over bar reinforcement kit, the 6-point Competition Harnesses.
The 'Kruss' Competition Harness uses 70mm wide shoulder straps wrapped around the roll over bar
reinforcing frame, 70mm lap straps and 50mm crotch straps, all of which plug into a single buckle with a bi-
directional lever release. The installation of the harness is illustrated overleaf for both seat types. Pay particu-
lar attention to the threading of the shoulder straps through the adjuster buckle, which should be positioned
close up against the reinforcing bar. Reducer studs are supplied with the harness kit and are to be used for the
lap strap anchorages on only the Competition Style seat.
Recommended seat and seat belt fitment combinations are as follows:
1. - Competition Driver's Seat (A111V6034S) 1 off
-
Competition Style Passenger Seat (A111V6035S) 1 off
Roll Over Bar Reinforcement Kit (A111A0245/6S)
1 off (LHD or RHD)
6-Point Competition Seat Belt Harness (A111U0378S)
2 off
2. - Competition Style Seat (A111V6035S) 2 off
-
Roll Over Bar Reinforcement Kit (A111A0245/6S) 1 off (LHD or RHD)
-
6-Point Competition Seat Belt Harness (A111U0378S)
2 Off
3. - Competition Style Seat (A111V6035S) 2 off
(using standard 3-point seat belts)
Note that fitment of the Roll Over Bar Reinforcement Kit precludes the use of the standard 3-point belts,
and that the Competition Seat Belt Harness is not approved for road use. Consequently, only option (3) above
is suitable for road use.
