I have the hatch pop kit. It has the 600N struts. I know it is only supposed to pop the hatch open...but when warm it opens the hatch completely. So, my thinking is "would a 600+N strut open when not warm" and "has anyone found a 600+N replacement?". I am unaware of which auto the pop kit's struts come off of...but think that an aftermarket replacement may be 600N plus given there's a 550N replacement for the oem 535N strut.
