I purchased a full set of seals for my 78'Z from Motorsport. I only installed the door seal on the drivers side because it seemed too thick. I have to slam the door really hard to close it tight and the road noise is more than before. I was hoping that over time, it would compress. It has been 6mo. and no improvement. Does anyone have any tips. thanks

Try searching "Kia weatherstrip". No, this is not a joke.

Thanks I'll check it out!

Weatherstrip from Precision is generally one size fits all crap. I installed it on my 240's inner rear hatch and the doors and could not get either to close without violent slamming. It also raised the height of the hatch nearly a quarter of an inch above the roof on the passenger side.

The old adage of "give it 6, 8 months or a year to relax" is BS. Not acceptable. You have two choices as I see it: buy the oem weatherstrip from Nissan (good but expensive) or go to the pick and pull and get creative. I found a Kia sportage with very nice door strips and took the rear hatch seal from mid-nineties Acura Integra. The doors close as they should with no air or water leaks and the hatch closes with a nice tight thud.
