Headliner is complete

Here are pictures of the finished headliner.
We decided to do the C-pillar covers as well, as they weren't perfect and would've needed doing in the near future.
A complication of doing this was the plastic locating/securing tangs on these covers needed extending by plastic welding, as the originals were barely engaged in their mating slots.
We also replaced ten of the headliner clips around the sunroof opening (BMW part #51441938868) - some were broken while others looked like they would break soon.
Ideally, all 16 clips should be replaced but I only had 10 new ones on hand.
Original clips were cadmium plated (gold colour), while the new ones are zinc plated (silver).

Overall I'm very pleased with the final result, especially the fact that all the original headlining fabric (albeit with new closed-cell foam backing) remains in the car.

BMWWGN,

1. Final result looks great. Congratulations.

2. As I am not familiar with the 850CSI I was wondering if he sunvisors were re-done or is that the original seam?

Regards,

Slfan

Thanks rogbmw
Your B12 is definitely worth the effort to restore.
Did you refurb or renew the headliner?

Hi Mate

Just bought a 840ci here in Oz,my question how easy was it to remove the material from the pillar.My car has a broken C pillar ( the tabs are snapped off ) am looking at getting a new black colour C pillar and transferring the material from the broken one onto the new after remoing its covering.

Seasons Greetings David!

I've learned a bit about these pillar covers from having my own set done, so I'll try and offer the best advice I can, based on this.

If the C-pillar cover is the original, the material should come off easily, as the foam backing will most likely be knackered.
Be sure to clean off all foam and adhesive residue from the fabric and the cover, then launder the fabric (cold wash, delicate cycle with a mild detergent, dry in the shade).
Actually I'd recommend doing both covers, in order to have them looking the same.

Get a plastic welder to repair any broken tab(s) and extend them slightly so they engage properly upon installation.
A new cover will give you the same short-tab issue I had, possibly leading to more broken tabs, and will probably cost you more than the weld repair on the old ones.

You can either fix new closed cell foam (1/16 inch recommended) to your fabric sections, or opt to re-trim both pillar covers with just the (laundered) fabric and no foam backing - depends on the look you want.
Also, depending on the colour and type of fabric you have and the weave, etc, adhesive bleed-thru is a concern here. Fortunately this was not evident at all with the tightly-woven backing on my CSi's charcoal-coloured velour fabric.
Use a good quality spray adhesive - ask a reputable trim shop what they recommend.
In fact, if you want a first class result, just give the trim shop the entire job!

Hope this helps.

Thanks Nick,

I'm very pleased with the finished product.

I'm hoping to have the whole car sorted in time for the Classic Car Show here in February.
The BMWCC display will be all E31's, celebrating 25 years since the 8-series entered production.

It's hard to believe this gorgeous coupe was an 80's design, and that my own car will be 20 years old in March:happybirt

Happy New Year!

We recovered everything with new OEM material of the correct thickness. I reread my post - for clarification, my B12 is the only silver B12 5.0 that was made, not "the only B12 5.0" made!

Your car looks great!

Thanks rogbmw

Congrats on the purchase and on the work you've been doing on it (Btw, why didn't you buy the headliner from the dealer? it is not much expensive, i did that to both my e31s).
Unleass you didn't do it yet, please registere to 8coupe.com ..it's the E31 widest registry worldwide i guess :)

Thanks Cosmic.
The two main reasons I did the headliner that way were cost and originality.
Can you imagine the cost of shipping the entire headliner assy from Germany to NZ?
Double that figure for dealer mark-up then add the actual cost of the part - also heavily marked up - and the price would have been exhorbitant.
I was also informed that the Anthracite velour headliners for the E31 were NLA from BMW.
Assuming I could get one, that would have left me with non-matching A-pillar and C-pillar covers, sunroof switch panel and rear shelf.
These could not be re-covered to match, as the original fabric is NLA.
Also it was unlikely that I could buy replacements in the same fabric and colour, but even if they were available = more cost.

Hence the decision to go with the lower cost option of re-using the original fabric for the headliner and pillar covers, and without the need to re-trim the sunroof switch panel or rear shelf, as they are still fine.
The result is a superior (better than new) headlining, utilising an improved closed cell foam backing and retaining both the original headlining board and the original Anthracite fabric.

Regarding 8coupe, if you are a member yourself, you will see that I joined that register early last year.

That is an impressive list of cars you have there!

I recently decided to do some detail cleaning under the wheel arches in preparation for an upcoming car show, where the car would be judged in a BMW Car Club team of two.
Starting with the left front corner, upon removing the plastic liners I came across some surface rust that had developed, due to poor sealant around the aperture for the brake/fuel lines and wiring in the inner wing.
Water had penetrated and soaked beneath the loose sealant, with the result that the metal surface had started to corrode.
It's also possible that a knife or other sharp tool had been used at the factory for trimming sealant or masking tape in this area, exposing the bare metal to the elements.
I had to remove quite a large area of sealant to locate the extent of the corrosion, which I then treated with phosphoric acid and rust converter before applying POR-15 silver rust preventative paint. Finally a coat of Dinol corrosion inhibiting compound was applied.
I was a little anxious about finding a similar problem on the right front side, but was relieved to find the inner wing structure is different on that side and all sealant had been properly applied there, with no induced corrosion.
Each of the four wheel well areas, including cleaning the shock strut, brake and suspension elements and the inside of each wheel, took a little over four hours to complete!
Other areas under the car also needed detailing, then the body paintwork was treated to some 'Meguiar's' compound and finished off with Carnauba wax.
The interior and engine bay required very little preparation.

My car was teamed up with an Alpina B12 5.7 for judging in the Car Club team category at yesterday's show.
We didn't win, but came away with a minor prize which included some more of Mr Meguiar's fine product, and I've learned a lot about this level of displaying cars.
Not sure if I'll to do it again, but I enjoyed the experience all the same....and the car has never been cleaner!

A few pics of our two cars in the concours area.
Lighting was poor for photography, due to trees casting shadows, and the uneven ground didn't help with the presentation of my car.

For those who are wondering, the B12 5.7 is the ex-Peter Rice car, which now resides here in NZ.

[Comment: you know you've been to a car show when you can still smell the Carnauba wax on your fingers three days later!!]

it's actually a PITA living far from manufacturer's main warehouses to get parts. I somehow experience that with the Supra. But be assured that even here in Europe it is not easy to get some E31 parts, many of them are discontinued/NA for long periods of time (until a few orders of that part show up, so they do another batch).

The condition you had your car for the show was absolutely astonishing! I wish i had so much patience to detail the cars! :)
really GOOOOD to see that uber rare B12 5.7 too! i think less than 100 were made, if i recall 8coupé.com correctly!

I'm registered on that website aswell, with both the actual cars, and with one other i owned in the past. I owned another two E31s too, but i was not able to get the cars' informations when i discovered 8coupe.com so i could not register them! :(

Just had my inner wheel liners off my 850 CSI tracing an ABS wiring problem and that part that goes towards the engine looked ok, what was showing signs of rust however was the hole where the wiring comes out of the bulkhead with the big rubber cap that you can just see in your 1st picture so my be worth just pulling those covers as well and checking the edges there.

Car looks stunning well done, and if and when I am in NZ I will come and search you out to check out that motor its on my list of places to visit before I shuffle off this mortal coil ;)

Thanks chadderz - I had a good look around those front bulkhead wiring grommets on my car...all good, both sides.:)

One thing I did find at the rear though, is the four main subframe mount bushings are quite hard and brittle, with their exposed flanges starting to break up.
So a new set of these is now on my shopping list.

If and when you do make it to NZ, you'd certainly be welcome to come and see the car.:cheers:

Just 57 Alpina B12 5.7 Coupes were built - 56 LHD and one RHD.
They are included in the total 850CSi production of 1510 cars.
Cheers.
