I found out the hard way when I was reaching into the trunk for something and the damn hatch came down on me and almost knock me out hehe. I have the replica Nismo wing but it was fine in the summer, I notice it gets worse when the temp gets colder and now with 25F the shocks are not holding up at all.

 

Yeah I know how you feel, I got a good bop in the head while working in the cold under my 4th gen Maxima. Those shocks suck in the cold, that's why I like the Z's hood prop. That thing'll last forever and it saves weight.
