I have a question about the allowance of chassis stiffening for use in EP.
15.2.B of the '01 rulebook(sorry, it's the latest I own) states:
        Chassis, frame, or subframe may be reinforced, provided components and 
attachments are not relocated except where specifically permitted....
This is a pretty broad allowance and I want to make sure I apply it 
properly.  At what point does an arrangement of steel tubes within the 
passenger compartment, engine bay and/or trunk with the sole purpose of 
stiffening the chassis, become a roll cage controlled by the rules of 
the GCR?
Basicly, I'm looking to stiffen my chassis with a 'cage like structure' 
but don't want the extra complexity, cost and weight of a full cage 
under the GCR.  For example, I see no need for side impact foot 
protection...
It would seem that 15.2.B is sufficiently broad that I can pretty much 
do anything I want to stiffen the chassis and as long as it's not deemed 
to be 'unsafe', I'd be legal.
Thoughts?
