I have a factory truck spoiler that I want to install. Does anyone has a patern or a diagram showing where I need to drill the holes in the truck to attach it?

3M tape? lol

What kind of spoiler is it? There were a few different OEM spoilers for e30s.

doesnt matter what spoiler it is lol....what i would do is put a couple of rows of tape along where the bolts from the spoiler sit. Then gently sit the spoiler where you want it to sit. Mark around the bolts with a permanent marker onto the tape.You drill in the middle of where your mark is, drill all the holes, put the spoiler on and tighten a bitch down.

Hey Matty, yes I understood what you meant. It's was a simple, logical way to do it.
But I think the specs that Sam provided should ease my pain a lot..

That diagram look slike someone drew it free hand. It just looks wierd.

Just use 3M tape as mentioned. Why drill holes in your metal

Thats how I mounted mine on my 325, used that diagram.

I tried the diagram and the tape methods. A combination of both will ensure you don't "miss".

After you drill, get some of that touch up paint in the little jar with the brush on the lid, any color, and paint the bare metal. Let that dry THOROUGHLY BEFORE YOU INSTALL THE SPOILER unless you love rust traveling under the paint and ruining your trunk.

I finaly did it today.

I used to dimensions provided above and I was right on on 5 of the 6 holes. I had to work the last one a bit.

Looks good!

Once the car is clean!
I'm doing bodywork right now, so you can imagine how dirty the car is...

i went through the same thing.. by using the tape on the end of the trunk did help, however it was not perfect and you need to keep on making some holes bigger than the other ones so that it would fit. it is hard to get this right the first time as the used part has saged/aged/moved around a bit. you should also apply black silicone stuff around the holes to have no leaks, and dont worry as it is removed easily from part and body if needed.
