Below is the actual rules that I was referring to. This is in the Solo II modified section (Autocross) where our cars compete. Here is a link for the entire rule section.
http://cdn.growassets.net/user_files/sc ... 145885779418. 3. Materials (all tubs)
a. Ferrous metal (containing iron) must be used for all primary load
bearing structures of the car. The primary load bearing structure is
the main tub or chassis and its connections to the suspension. No
aluminum cages or roll bars are allowed. Any ferrous or aluminum
alloy is permitted for suspension arms, location links, and uprights/
spindles. Beryllium and beryllium alloys are not allowed anywhere
on the car.
b. The exceptions to the above are parts of the donor production cars
that were originally non-metal. In all cases, replacement of these
parts or addition of more load bearing structure must be by metal.
Lighter replacement sections may not be used between bulkheads in
a Stock Tub without it becoming a Modified Tub.
