Roof rail holes.

[loanrangie]

Can some one please tell me how many holes there are under the gutter trim on the lower part of the roof.

[Globetrotter]

There is an easily seen rubber plug in each one, so count the plugs

I put short rails on mine, there were 3 each side. Obviously for long rails there would be at least one more each side. One thing to note is that if your car is a few years old, these holes may be a little rusty so I would recommend you tap the thread first.

Yes, the plugs. So 4 a side then for long rails.

So is that just one each side at the front ?

[IndusD4]

Correct. See this video from Powerful UK on how to fit the long rails.

Yes 3 on the raised part and 1 only on the front lower end. Today I put the backbones on for the Rhino rack and tapped out the holes first as they're full of paint. Makes life much easier when trying to get those bolts in.

Just a note.
The plugs on earlier D3s just push in but on my MY08 they screw in.
Worked that out after trying to pull the first one out as per YouTube video and snapping it off, leaving the threaded section in the hole.

Uh huh, that must be how they keep stripping the thread when fitting rails(dealer i assume). I was wondering how they managed that on what must have been a brand new car when mine were fitted.

I'm not the only one who has had to drill out and tap the old screws from factory roof rails when fitting a front runner/other new system that requires removal.

I like the idea of backbones but when fitted with the platform rack to our Colorado the wind noise was unbearable over 80 KPH.How are they on the Disco noise wise?
