Rieger diffuser owners, how did you secure the top part?

Delta Goose · 08-05-2013, 01:49 AM

It seems like the tabs only slide in, as opposed to snapping in. It probably wont ever slide out unless someone pulls on it, but I was hoping there was still a fix.

Thanks!

I left mine alone. I secured the whole thing with the middle bottom screw and 1 side screw on each side. I found that if more of the bottom screws were used, it deformed the shape of the diffuser.

They include a couple black screws to anchor the taps on the top of the diffuser but its over kill if you bolt the side fins up your good to go

I screwed in the 2 on each side that requires drilling, as well as 2 on the original holes. It seemed pretty secure, but pulling on the top edge popped it right out.

I just slid them in place, and secured the bottom.

I think most people just slide the tabs in. The instructions from Rieger show using self-tapping screws from the inside of the diffuser to secure it. I personally think it's overkill.

Just trying to figure out how to straighten out the bottom at this point. Looks kinda jacked from the rear with the muffler side being like 2 inches lower than the right.

So far no issues, even at autobahn speeds.

anyone ever figure this out? I have the same issue and can't tell if this is by design or if it is deformation from shipping or something....

Any thoughts?
