I've driven around 90.000km with 42mm spacers on my old WG and 30.000km with 35mm spacers on the new WG, the tire wear is ok, front bearings and ball joints never complained, Moog tie-rod ends lasted 60.000km.
I can't comment on handling too much, with the Addco rear sway bar it's been just fine on twisty roads, I like keeping momentum around turns
My wife doesn't enjoy it as much though
