The first couple I did when they first came out... I heated the crap out of each of the dozen or so little fingers up and down each side of the little window... It's such a small space in there anyways and I always dreaded those two windows. Then I had an epiphany.
The reason I hadn't even bothered to shrink was because it's problem was not top to bottom it was side to side. 
Why it took me so long to realize that I could easily solve the problem I'll never know. 
What I needed to do was simple. I cut those out of a strip from an eyebrow where the film was running longways along the factory edge instead of the usual up and down like you normally would on a side window. Now ...with the grain turned in that direction they will shrink just fine where it needs to be shrunk. Other quarters are the same way...depending on which way the majority of the curve is ...I think about it when I cut the piece of film for it so that the shrinking can be done where it needs it the most...
Just thought it might save someone new to tinting a little anguish.
i hate those little mothers. Putting the grain to the sides is a big help. 
you are a real blonde ar'nt you . just kidding
ha ha ha bs i was bieng sarcastic. saying taking that long to figure that out was showing you where a true blonde . but im glad to know of your decorating pattern 
See there? I was editing as you were typing. I knew what you thought ...Didn't take me long to "get it"...
