vince,
Wilkinson pantera makes a complete aluminum set up front and rear.The only thing is i don't believe any of it is adjustable,just a replacement of stock.I have a completely adjustable front aluminum suspention from jhp motorsports that absolutly looks and works perfect.You can obtain a large amount of castor and camber settings which means alot in the handling of the car.It also incorporates std ball joints that cost @ $40 to replace.Price out ball joints from detomaso.I do believe jb offers a rear set up also but i already had a steel adjustable set up from ppc in colorado.As far as weight goes,the stock system is just as light as the billet system so weight savings is not great.I would not go for the expense of aluminum unless it can be used to adjust geometry of the car.
