Just got the RFY Diffuser for the ap1, but I have no idea how or where to mount the brackets. It came with 3 sets. Long, medium and small. It's like they dont fit anywhere, I've had two different diffusers before, but this one I dont understand at all?.. Any diy out there?

I don't know many people running that diffuser... I was looking at getting one of those myself but came across a good deal on a JDP one.

Anyways, post some pictures of the underside of the diffuser and brackets... maybe we can suggest ideas.

 

have you hit a vendor like Evasive Motorsports and ask them maybe to help contact RYF for at least a template?

 

Have asked both RFY and Evasive, still awaiting reply. Heres a pic of the brackets, I will take a pic of the rest if the hardware once I get home:

 

Heres the screws, 3 of each except two big. I think the black are for the side CF vents? and the silverish for the center diffuser?

 

This is the centerpiece, I tried to mark where there is drillmarks, but those places doesnt fit anywhere under my ap1 if I was to cut them out and put a bolt in:

 

Looking at pictures of the diffuser installed on other cars it doesn't look like they drilled a hole right in the center of the rear portion of the diffuser.
Look at this picture. Looks like they drilled a hole on either side of the center tunnel.



Im assuming you'd use the long bracket on there and it would mount somewhere to the chassis or body of the car and not the rear bumper.
Try that and see if the other brackets are useable elsewhere.
I wouldn't rely on those drillmarks.
That center one could be for an additional rear fin for all we know
