We were just wondering if there was a cost minimum for titanium ($/lb)? We have a few parts that we may decide to use on the car but we were not sure what to use for the costing table.

As I understand it, cost minimums that are given are given, everything else has to be costed at retail. So, our Ti fuel tank for last year had a bunch of receipts for Ti plate. Mighty expensive fuel tank.

I have a question regarding the Materials Costing.

The rules say Mild Steel (like 1010) is $0.30/lb and Alloy Steel (like 4130) is $0.60/lb. Does this mean that all 1xxx Steels must be cost at $0.30 and all others at $0.60? I take it 4340 must be cost at $0.60, right?

In the rules, Aluminium is $0.75/lb. Does this mean that all alloys of Aluminium can be accounted at this price?

Yes
Yes
and Yes

Why on earth would you use a Ti fuel tank? Aluminum is lighter.. of course theres the whole E85 thing but I'm sure theres a easy fix for that.
