So an overall look compared to a set of NOS seals provided by
@Paul Baker
Gen bmw on the left, pattern on the right. About 2mm thicker but the rubber is slightly softer, I'm hoping that this means it will be a tighter fit on the top and helps with wind noise
Bmw on the bottom, pattern on top. Bmw is more like a low density rubber whereas the pattern is like a rubberised foam which deform more and is thinner. I know the bmw ones do need some shaving to fit up properly so this is probably a good thing. They also look a damn sight better.
Up at the top of the b pillar the bmw part has a taper where the rubber piece hollows out before the sealing strip. The pattern is solid throughout. One thing to note is the left and right seals on the bmw parts aren't consistent in firmness, one being much stiffer than the other, whereas these are both similar.
The biggest, and imo only detraction for me on these is the fact the seals glue on, there is some exposed glue and does look a bit unsightly.
Overall, I'm happy with them (other than the issues with contact which we have found). They are well priced and were shipped quickly once the order was placed was finalised, they fit and seem to seal well and are a better option than the bmw seals if you can find them.
