Roll Cage

[Greg Amy]

I'm not sure where the confusion is, it's pretty simple.

The SCCA GCR governs how cars are to be built. Section 9.3.39. "ROLL CAGE/ROLL BAR" states:

"Shall comply with Section 9.4., Driver Protection Structures."

Section 9.4 has two different areas* describing roll cages:

- 9.4 ROLL CAGES FOR GT AND PRODUCTION BASED CARS
and
- 9.4.5. ROLL CAGES FOR FORMULA CARS AND SPORTS RACING
CARS

Super Touring cars are not formula or sports racers; they are based on production cars. Thus you will follow those regs. If there are any Super Touring-specific deviations within those rules, then you'll follow them.

GA

* Yes, there's Appendices I and J, but those are both for cars that have already been tech'd and received their logbooks. Since you're doing a new build, you must follow 9.4.

Okay I think I get it now. So if no specific exclusions within 9.4 for ST (i.e. 8 max attachment points vs unlimited) we go with the general rules in 9.4.
Thanks

Correct.

And off the top of my head, I don't think ST is subject to the 8-pts of attachments limitation. - GA

Read 9.4.E.1 and 9.4.E.2. Page 102 and 103 of the GCR linked by Greg. It doesn't get much clearer than that..

for STx, you can build whatever you want for a cage- anywhere from as simple as an IT/SS cage to a full-monty GT cage with 87 attachment points. good luck meeting min weight with that though.
