The ST coil overs are exactly the same as kw variant 1 coil overs but mild steel bodies ( confirmed by KW)
They ride very well on most roads, if the road is very poor they can be a little to firm . I have to drive some horrible back roads which is making me consider swapping them out. I am running fairly low so I am going to raise it 10mm all round first to see if that improves it.
