I made my own lower control arms last year, solid aluminum bars, with 3/4" QA1 heim joints.


I forget off the top what size bar i used, 1.25" dia probably

couple of questions...
1) those heim joints make this think rattle and clunk like a damned tank, normal? I'm assuming any TINY bit of slop is what I'm feeling

2) should I have any concern what so ever of breaking these LCA's at the track? These things a pretty beefy, but with launching at 5500rpm or so, just want to make sure my rear end comes with me.
