Don't remember who the maker was, but a couple of years ago, a lower rear billet aluminum a-arm broke in two while a Pantera owner was out driving. Look closely at any aluminum arms offered: if they have cut-aways in their construction ANYWHERE, for any reason, I'd avoid them. Especially in the heavily loaded rear suspension.
There are aluminum covers available for stock steel arms- which are lighter and stronger than alloy arms and look as 'blingy', or stock steel arms that are plated. The stock alloy arms on other brands of sporty cars are forged aluminum which is far stronger and tougher than machined or welded 'billet' aluminum.
