2 major issues,
1- The inner and outer bushing MUST be spherical. I have seen broken ears on stock uprights from this style but beyond that these will cause a bunch of stiction as the bolt holes dont necessarily sit parallel and move a lot in angle through suspension travel.
2- Threads in bending are about as awful of a decision on a track car as you can make. They are about 10-15% of the strength of a rod sized at the MINOR thread diameter. And these make it worse with threads being so far outward towards the shock mount.

i bought on amazon, but its the same brand summit sells (design engineering)
anyone got a rockauto discount code that's still good? lmao
I'm still surprised SPL hasn't done anything for the Evo platform. I recently purchased a bunch of arms for my Supra and they are seemingly very nicely done.
For the momentum parts, this is what kills me. I would never trust this joint. Carrying bending loads through threads, and high load with the entire suspension load going through it is just bad engineering. These things basically aren't engineered, they're just designed and made.

I'm not an engineer, but I think you only need tensile strength there.
