I installed my Robbins top just before winter myself and yes it was extremly tight almost could not get it to close. I didn't take it down until this spring. The first few times I had to help it close, now it will almost close with no help. Seems to go up and down just fine.
The problem I am having is it got up to 80 degrees a couple of weeks ago for the first time (Salt Lake City, Utah) and the glue around the window heated up and came loose.
I talked to Robbins they were very friendly. They said they had some tops go out with bad glue and they are in the process of replacing them. They are shipping me a new top this week. I just wish I didn't have to put it on again......not that fun!!!!! We'll see if this new one holds up.
This was my 3rd top. 1st one window cracked and porsche replaced it under waranty. That one only lasted 2 years and cracked again...this time no waranty. I bought the robbins top with glass thinking this would be my last top, guess I was wrong, here we go for number 4
