This has to be a joke. Conservatively, that would be a NINE HUNDRED POUND block of aluminum. 7075 is about $7-10 per pound. That's a $6000-9000 block of aluminum. No sponsor is stupid enough to waste that kind of material. This also ignores the fact that there is no such thing as 7071 aluminum. The frame would also be substantially weaker than a properly constructed welded tube or sheet-metal chassis.

Basically...obvious troll is obvious.
