know for sure of struts in the last 18 months requiring x-ray and that is what my certifier has indicated to me for mine.
no weld, no x-ray.
but mine are for changing height and changing spring rates in a club/rally car.
Relax, I'm not in NZ anymore....
I've been pricing it up, and camber plates + sleeve kit
= thereabouts of a cheapish coilover kit
which will bolt in and work without discovering how not to build suspension....although it will become a game of working out which coilover packages are crap out of the box...
**** Awaits the raging debate of bc's, d2's, Tein's, HSD's etc etc****
Although there is the advantage of buying relevant bits and building the suspension up, rather than spending $$ on things that are not required.(i.e. camber plates)
Just to confirm - the diameter/ shape of coilover springs is definitely different to regular springs?
if so, its a shame - -otherwise could buy bits as I need them, as opposed to in one go....
