Fitting wind deflector - solved 'how to'.

I actually completed my install on Saturday having visited a dealer to get just those measurements.

Also for info, the boot brackets need 4 x small plastic speed nuts to secure the screws. These are not listed on realoem.com or anywhere else that is easy to find. However, I can confirm they are a standard BMW part, no. 63171367868 and cost a very reasonable £0.23 + VAT each.

Hope this helps,

James

Hi James
Excellent write up and very helpful, my issue is with the boot fitment, I've bought the "rawl plug" style speed nuts but the right hand side won't tighten up enough to allow the diffuser to be held tight in the boot are these what you fitted?

Here's another photo to hopefully explain the situation. The pic I wanted to post is too high a resolution /file size so I can't post it.

Hi ScoobyR1,

These appear to be the speed nuts I bought. I just pressed them into the holes in the boot and screwed the bracket into place. Are the screws definitely the same as used on the LHS ? The speed nuts should be quite hard to press into place.

I hope this helps.

Cheers, James

Hi James

Thanks for reassuring me I had the correct fittings. I could only fit them in one way, turned through 90 degrees and they were really to tight, the other way - 90 degrees and they were really loose. Maybe I need to put them in the tight way and just be a bit more forceful? Possibly the size of the screws I got which seemed a wee bit small, although I got the part number off realoem.

Will check this out when I'm back home on Tuesday.

Cheers Stu

D'oh!!

Can't believe how dozy I feel!
Simply rotated fittings through 90degree and pushed home more forcefully and job done.

Many thanks for pointing out the obvious

I can use the body as a reference point, OR the top of the rubber, but i get a 5mm difference.... quite a lot!

well after a lot of "faffing and measuring" finally mounted these. used a small 4 mm drill bit and used a piece of wire to "find" the threaded hole behind, and opened the small holes in the cover with a dremel . all worked out just fine with a tidy job.
noted the comment about the threads being tight so used some plastic grease on the threads which made them much easier to tighten without feeling i was just about to snap one.
I cant believe how much difference the mesh makes, at motorway speeds there is far less buffeting. I've ordered a kit to stow the mesh in the boot, but i cant see it coming off much unless i have a long journey with the roof on and want a little better visibility....

thanks all

Just got a set of brackets today big thanks to jamesditchy for sending me his spares

I've noticed they are marked let and right but anyone tell me if that is as if I'm stood in front facing the car or if I'm sat in the car? Probably a really stupid question but thought it best to check before I take a drill to the car

It's on! Even had time to take it on a run to celebrate before it started pissing it down.

Thanks for posting the pictures made fitting dead easy

Well done 85 genius. I finally fitted mine last Monday (Bank Holiday) and as promised previously I said I would post some pics, so here they are and I hope they might help.
Remember measure 6 times and then try a small 2mm hole! Takes a lot of nerve before drilling, but once you start it's fine.
I recommend a bradle a hand drill, but each to his own

Good luck

Did my measurements measure up

or did you have to make adjustments?

Hi Russ, sorry for delay.
I think your bottom measurement was spot on, 65 mm from bottom of the trim at the base. as well as the 7mm measurement between the side of the bracket and the back edge of the hoop. These were the two that I really found the best as it enabled me locate the bottom hole exactly. Once I had put a small pilot holel through the plastic of the hoop and found the fixing, I knew it was going to be ok. The top hole I didn't use a measurement (except the 7mm gap between edge of hoop and bracket) and just centred the drill point having lightly fixed the bottom end of the bracket. That meant the top hole was also spot on.
I did the same for the next hoop, taking your measuremants for the bottom position. That was spot on too, and then for some stupid reason thought it would be clever to take my own measurement for the top fixing from the side I had already done, rather than use the bracket as a template.
The result was as per the photo, a nice key hole! because my measurement was out by about 3mm. I did the pilot hole and must have hit a void because it went in ok and I thought that meant I had found the centre of the fixing...I hadn't! So I had to exppand the hole downwards.
I should just have used the bracket as a template, and that shows how accurate you need to be, which I wasn't

So the moral is, your measurement for the bottom hole is just what I needed and correct, and I would forget the top measurement, just use the bracket as a template with the 7mm measurement between the edges.
At least I think thats the best way, and as someone said earlier, if you get it a bit wrong like I did, there is a bit of leeway to cover it up.
So now I have had to expose my incompetence with a photo, doh!

So I am really grateful for the original post, I would not have been able to do this without your measurements.
Thanks.

Hi all. Great post. I just received my wind deflector and of course now realised my car needs to be adapted to fit the deflector. The place on eBay I ordered the wind deflector from only supplied the wind deflector. I am after the part numbers for the brackets, torx bolt and cover cap. Anyone know what they are so I can try find them on eBay?
