I just stumbled upon the Nismo front upper arms.

Are they anywhere near as good as SPL?
My friend works at Nissan parts specialist, and can get lots of Nismo parts directly from Japan for cheap. If those ones are good I could get him to get them.
EDIT: OK upon more investigation, it seems the Nismo version are the exact same as the SPL brand? That is amazing if it is, my friend should be able to get them from Nissan at much cheaper price than me shipping it from the states.
