Looking to lift the front end of my 2014 Z71 CC up a little bit and I am wanting to avoid putting any strain on any of the suspension components. I have read through this entire thread and I have seen that with the 5100 at the top setting they seem to ride a little bit more rough, which I am not worried about. The thing I am worried about is how they perform in the cold (around -15F temps)? Are they even more stiff?
