These shots were sent in by braindilley, and clearly illustrate the seat back clips that have failed on several cars. They are a very tight fit, and take quite some work to slot back in place once they are glued. The glue info come from our team chemical engineer, FWK-Z8

1.) Clean both surfaces with a fine 80-100 grit sandpaper to remove any residual adhesive/roughen up the mating surfaces.

2.) Spread a thin coat of cyanoacrylate (like MXBON 105, or any other good industrial superglue) to each surface - make sure you get it to the edges of the parts so as to eliminate stress concentrations that would allow peel.

3.) After getting the initial adhesion, run a bead around the perimeter of the clips to allow the adhesive to get in by capillary force . If possible clamp the two pieces together for about 2 hours.

4.) Wait overnight before reinstalling the shells.

5.) The top hooks, which are the ones that fail, slide up to engage. The bottom ones push in when the top hooks are fully engaged. The hardest part of the fix is re-installing the seat back. Due to the thickness of the leather, it's difficult to get the top hooks to "click" in place. Go slow, be patient, and you'll eventually get it.

I have "fixed" my seat clips numerous times; but eventually they come loose again.
I notice that they flex whenever you enter or leave the car (driver or passenger) ad this pressure eventually breaks them loose.

Has anyone discovered a permanent fix?

Not sure it applies, but I haven't noticed any ALPINAs with this problem. Andrew would probably have info on this, though if they have. The ALPINA seat backs are different than the Z8 (they're not glossy), but the entire seat could also be different as far as I know. I don't think that's the case, but may be something to check out.
