Anyone know of any special way to install the roof vane diffuser. The one I have has a lip in the front that seems like it's not going to sit flush. I figured someone here must have experience with this piece. Any advice would help!

 

are you talking about the rear spoiler vane from an STi? the one that goes over the upper part of the rear window??

 

Ya that one. Just the vane part tho. There's no spoiler.

 

Is it the OEM one or an eBay product? Snowflow did a great write up, just put his name in the search and look for the thread.

Are you taping or drilling into your frame?

 

im taping it. ill look it up lol

 

do it yourself, its very simple. It just takes time and some kajones (*****).
put double sided sticky tape on each end and put on the car where you think it looks level. take 30 measurements and than double check those all again, when your good with the placement, COMPLETELY mark around the end caps with sharpie, not just the holes.
NOW, once its marked you get a center punch and you drill ONE hole, put the spoiler up there and put a bolt thru it, make sure ****s still is lined up good. Repeat this process until all holes are drilled.

and i forgot to add, DO NOT drill thru all 3 layers of sheet-metal!!! (this is stupid that people actually do this)
Drill thru the outside layer and ONLY the outside layer. Go to the hardware store and buy short stainless steel wall anchors http://www.almabolt.com/images/mason...allanchors.gif Those will suck up to the top later for sheet metal and hold the spoiler on stronger than you need, do not over tighten.

Before you screw it down, get a clay bar and a rag with some WD-40 on it to get that sharpie right off, Than just put the damn wing one
