C REATING A NEW ATTACHMENT POINT
• Follow the recommendations for geometry and strap routing
described on Pages 24 to 26 to define the proper anchor point
location.
• FIA does not allow welding or drilling to roll cages, except those
conducted and certified by the roll cage manufacturer. Only
manufacturer specified roll cage bars must be used for racing harness
installation.
• For new attachment points to the chassis heed the following
WARNING box.
If you intend to drill a hole, make sure not to damage the fuel
tank, fuel lines, electrical wires, brake lines or other important
components. Any damage to such components can result in
fire, explosion or mechanical failure and severe injuries or death
can result.
• For new attachment points to the chassis you must use a FIA specified
reinforcement plate [see “Accessories & Spare Parts”].
• Drill a hole of 12 mm [15/32”] diameter for lap- & shoulder belt and
standard anti-sub strap attachments.
