If the intent of this rule is to keep a suspension member from contacting the track surface if it were to fail?,,,,Then I feel comfortable in my attempt to comply.
Lets face it,,,the rule book is written to keep us SAFE and play fair. Its GOOD. But at times can be vague. That why we have these forums, poles, questions,etc.,,,,
In my application, 'four link', the bottom bar is in compression and the top bar in extension. If one was to break, it could be held up off of the track surface with a simple piece of 8lb test fishing line.
So my 5/16 cable is kinda overkill.
As far as the diagional link goes,,, it would only fall as far as on top of the driveshaft.
thanks, RICK
