I would like to ask you two more practical questions. 
1. Are FIA bolt in cages that have been modifyed by adding more tubing 
are still legal?
2. If a rally car has no separate rear compartment and a fule cell is 
added in rear and this fule cell is FIA certified and has aluminum case. 
If the pump and filter are covered with aluminum enclosures are we still 
required to construct a fire wall? Many cars that have this setup don't 
have custom firewall and pass tech. The only car that I have seen to have 
this was Sprongl's S2. The rule book is unclear to me. How do you 
interprite this fire wall requirement.

Thanks for your expertise.
