Default Re: Sheet metal formed trailing arms - WHAT THICKNESS

Boy tell me about it. I was just quoted $1,600 in materials for my trailing arms. .085 for the main structure and .125 for the two internal ribs that the shock will attach to. From what the water jet guy said, they don't make 4140 in sheet form (as in a gauge size) and they were going to have to start out with .250 plate and grind it down to thickness. WTF???

I spent the better part of a week designing and redesigning my trailing arms just to find out they'll end up being prohibitively expensive.

Needless to say I said F that. I may consider doing my arms in 1018, but I'm so totally pissed with my 10Dez (everything has been a compromise) that I'm ready to take it and throw the damn thing in the dumpster. Someone hands me $35K, comes and gets it and they can have the f'n thing.

I'll be redesigning trailing arms and be using 1.25" tubing now. Why not, it's all been a compromise and a constant kick in the balls.
