Fitting wind deflector - solved 'how to'.

Hello. I'm about to do this, marked up the roll bar in accordance with the dimensions, but checking the hole distances from the body I get approx 5 mm out vs the marked holes using the brackets.

Measured a couple of times, can't see where I am making an error. - any suggestions?

Have you got the brackets the right way up?
 
Yes I think so. though if i were to mark the holes with the bracket the other way up they would match the dimensions !!

This is a 2006 car, would the rubber trim at the bottom of the roll bar be different?

the only thing I can think of as one measurement (10mm) is from the top of this and the other is from the bottom?

The first hole measurement is 65mm up from the bottom of the trim around the roll hoop up the centre of the bracket and the top hole 145mm from the bottom up the centre of the bracket.
Your measurement seems to be from the top of the trim around the roll hoop.
 
Also looking at your pics you don't seem to have the bracket forward enough. From the back of the bracket it needs to be 7mm forward of the edge of the front roll bar cover.
 
thanks for your comments, ill double check everything again. i measured 10mm from the top of the rubber trim to the bottom of the bracket with the bracket 7/8 mm from the split line as per your post, marked the holes, then checked the holes from the bottom of the trim. doing this i get holes at 60 and 140, so 5mm shorter than your dimensions, which seem very clear

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

I know you'll want holes in the hoop covers exact, as would I, but if you are out by say 5mm up or down, the bracket will cover the slight mistake.

Thanks Russ59.

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!! :oops:

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

Many thanks for pointing out the obvious :rofl:

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 :thumbsup: :thumbsup:

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
