I have Dave's shortened A-arms for wider wheels. These are probably the lightest, strongest, best fabricated arms you can buy which aren't custom made.
These are TIG welded also.
I was looking for something cheaper that 400 bucks for A arms. For 600 I can get the UPR kit with K member, a arms, coil-over & struts, so its not really worth it then. I just happen to have a set of H&Rs springs I wanted to use.
