Morning,
Just wondering if having bent rear stays or braces is allowed under CCDA Spec. Have tryed to read the reg but cant decifer a yes or no answer.
Oh by the way it is on a ute.
Also what you normally make the roll bars out of 50NB SCHED40?
Cheers,
Welchy

Rear stays have to be straight for CCDA.
5.3.4 (rear Backstays)
They shall be at angle of at least 30 degrees with the vertical, shall run
rearwards and be
straight and as close as possible to the interior side panels of the bodyshell

but does this still apply for the tray mounted bars in a ute?
i have seen Extreme winch challenge cars with bent rear stays but was wondering if this is strictly legal.

Extreme winch challenge is not a ccda event.
Back stays have to be straight
If you have backstays inside the cab, you don't need them in the tray, but becasue of room restrictions in a ute you can have the backstays on the tray.

so in that case do the back stays "have" to go to the chassis or is there a way around this?

Back Stays do not have to be chassis mounted. Under CAMS the tray is considered the body, but the regs on plates and attaching stand.
Same as within the Cab, cage is only attached to the floor not to the chassis.
I queried a CAMS advisory board member on this, and he stated that it is more likely that the body would separate from the chassis in high speed roll overs, if this happened then the cage being body mounted still provides a level of protection (seats / harness stay with body also).
