There is a new forumite (several months ago) who's mate bought a set for his Silvia or Skyline and IIRC he stated that one (or both) snapped after a few corners on their local track.
It may be fine day to day normal driving, but please be careful when you start to push the envelope.

I have read about these arms hitting the subframe or chassis when you have a low ride height, basically results in them bending and snapping eventually - CHECK IT OUT http://forum.miata.net/vb/showthread.php?t=342639

there are some thoughts here too - http://mx5cartalk.com/forum/viewtopic.php?f=30&t=35984&start=0&hilit=camber+arms

I was looking at them, but decided to not bother.

Si.
