As I write this I think it might apply to other Spyder variants but I've never seen one in person so I don't know how the electric top is designed. So 987 Spyder owners do you cruise the highway with the back section out? Does the AC keep up? How bout the top do you think this adversely affects it in any way? I read in the manual it's normal for it to stretch and return to form hours later. I feel like the factory back piece is not great for rear vision but it's probably advisable for pop up rain to keep it on. Anyhow what say you fellow members?
