I know the 914 steel front cross member really doesn't weigh that much but wondered if the ounce counters have weighed it compared to an aluminum 911 cross member and what the savings was?
I believe the aluminum was stronger and cheaper to produce (not to necessarily save weight) by Porsche.. Andrew |

I was considering the Al cross member also and got to thinking that Aluminum isn't as stiff as steel. The cross member is the part that actually reacts the forces from the front torsion bars. The torsion bars put the cross member in bending and the Aluminum being more flexible would transmit more of the loading to the chassis. In noticed some cracks starting to form around the area where the cross member mounts............ anyway I ended up welding a flat piece of steel to the bottom of the steel cross member to make it even stiffer. FWIW
