I'm a little nervous with my install because 4130 steel is a significantly stronger material than 6061-T6 aluminum. The aluminum has a yeild strength about 60% that of the steel, and it has a young's modulus (deflection rate) about 30% weaker than the steel. Not to mention aluminum is generally considered a much softer material. While the billet version is beefier than the tubing version it still has thin flanges where the arm attaches to the upright.

What I'm wondering now is, how much load is actually going through the rear camber arms under cornering, and is it enough that it could potentially be an issue? The billet version is also newer, have there been any accounts (yet) of them failing? I understand SPL is very well respected in the community for making quality parts. And seeing how NISMO also makes a similar billet aluminum camber arm there should probably be no cause for concern. This is most likely me just being paranoid... but I also couldn't find any other threads discussing this topic so here we go.

The Nismo part is an SPL part. They make them. No issues with SPL period. Stop worrying.
