where can i get a aluminum car chassis? or magnesium?

Question

for front engine, 4 cylinders, wheelbase 106",rear wheel drive,track about 59"

Answer 1

I wouldn't recommend either for a couple of reasons. First, aluminum is not a suitably strong material to construct a "regular Chassis" (I know, race cars have aluminum chassis, but they are usually "bird-cage" style and impractical for street use.

Magnesium is even worse. Did you know that magnesium burns really well? Why do you think the use magnesium in flares? The so-called "mag wheels" are usually alloyed with another metal - usually steel or aluminum to reduce theitr flash point!

I'd suggest you just go to your nearest steel supplier and welder and have them whip up a suitable frame. Don't forget, you'll need suspension mounting points, crossmembers, engine mounts and a whole lot of other stuff.
