SPL Parts Discussion

Also, shouldn't these pieces only be loaded in tension and compression? Should be plenty strong for that since they're made from a billet of aluminum. The struts do the load bearing, these only help to locate and control the wheel and upright. It's not like the toe arm replacement which has a load structure right in the middle.

Yeah I was skimming your suspension build threads earlier. IIRC you installed yours before the aluminum ones came out. Unless you've upgraded since?

Yeah they're only in tension and compression, but there's still pretty high bearing stresses on the upright flanges given their small cross-section.
Also the camber arm is one of the lower members on the upright. This means it experiences high cornering loads since it is closer to the contact patch.

If you want, buy a set of the billet one's and I'll trade you my steel one's for the billet one's

I haven't up-graded.
