Aluminum Vs Steel

[FRpilot]

i want to start a debate between aluminum and steel parts. which one would you guys prefer and why? i know that aluminum is lighter than steel, but how strong is that stuff? my friend said aluminum is better than steel for certain parts. what i'm talkin about is suspension and bracing parts in particular. for example, would you rather have an aluminum strut tower bar or steel? how bout do-lucks tension gauge set and floor support bars. they have aluminum and steel versions. wouldn't steel be better since it should be stronger and thus stiffer for bracing? what im worried about is aluminum crumbling up under pressure. i would love to have a lighter car, but im not sure if aluminum is strong as steel for bracing purposes. how bout aluminum coilover casing vs steel. i was looking into zeal functions and they offer the b6 (steel) and s6 (aluminum). which one would you guys go with?
