sparco seat and sabelt 4pt harness

back to the storage room to check out some parts. the red sparco seat i bought last year struck my eyes and i decided to mount it on the lancer. removed the railings it came with, i took off the shoulder and lap strap hole cover(whatever that is) and stitched the gaps to make it presentable. added a nice sabelt 4pt harness and "viola"! a nice bucket seat waiting to be mounted.



scoured the net again about diy installation for the seat and harness. and much to my surprise, it's very technical...

here's an exerpt from the clubgti.com forum

1) MSA requirements:
  • Racing requires FIA homologated safety harnesses. Must be 'in date'. The expiry date stitched onto a label on the harness is the last date the harness can be used in MSA / FIA regulated competition
    • FIA Appendix J - Art. 253 states that "one anchorage point for two straps [is] prohibited for shoulder straps." Since the MSA refers to the FIA for racing, 3-point harnesses aren't allowed for UK racing.
  • Sprinting / hillclimbing requires:
    • 3 point safety harnesses for Road-Going Production and Road-Going Specialist cars
    • 4-point safety harnesses for Modified Production ('Mod Prod')
    • 6-point for Hill Climb Super Sports Cars, Sports Libre and Racing Cars
      (all as defined in the MSA Blue Book)
    • ... but does not appear to specify FIA Homologation (please shout if you know this not to be the case)
  • Rallying requires FIA Homologated 4 point safety harnesses (minimum)
  • Rallycross and Autocross requires 3 or 4 point safety harnesses (minimum) but does not appear to specify FIA Homologation (please shout if you know this not to be the case).

However, the MSA encourages FIA-compliant harnesses:

2) Trackday harness requirements:
  • Subject to any event officials checking cars, eg whilst noise testing, none

Rough guide to types of harness in existence:
  • EEC Approved
  • Latch closing mechanisms
  • Turn buckle release mechanisms
  • Push button release mechanisms
  • FIA approved harnesses

Also, design differences:
  • 2 inch straps, 3 inch straps, or 3 inch shoulder and 2 inch lap
  • Clip on harness straps, designed to fit over eye bolts
  • Non-clip on harness straps, which are 'permanent' fixtures
  • 3-point, 4 point, 5 point and 6 point harnesses

other sites also have their own version of this. but what am i gonna do? since, im gonna use it for motor sports, i might as well follow fia/aap (philippine local governing body) rules...

off for further research
