and from what I can see, there isnt any provision for mounting the shoulder portions of a harness. how will you be handling that?
CARS (Canadian Association of Rally Sport) requires the use of 1.75" tubing for the main structure (very specific) and 1.5" for other tubes.
The cage meats the CARS (i.e. FIA article 253) requirements for cage design. FIA Article 253 can be found easily online if you're still curious.
The shoulder harnesses can be mounted on the tube between the rear shock towers. This is a less popular design lately. HANS requests that harnesses are intalled within 8" of the seats backs for optimal sfety for their product. But, if further, they ask you to cross the harnesses.
