Is there anything else I need for an R1 lip to be functional? Installing on a non R1 car

Thanks

 

R1 lip should just replace the touring lip and use the same hardware, nothing else needed for mounting

As far as function, I think the R1 trim had brake ducts guiding air from the air dam channels to the wheel wells (?) But someone else will have to speak about mounting those.

 

Yeah, the Right and Left brake ducts that snap into the Right and Left undertray pieces on the R1 model to get the air from the lip into the wheel well.

The two under tray pieces Right and Left of the center undertray have different part #s from memory- not sure if the R1 brake duct pieces will snap into non R1 R/L undertray or if you have to get R1 pieces for those as well.

 

There's longitudinal slots on the oil cooler guides to accept the brake duct pieces, when I had several sets here. Only problem is, not available as a separate piece and judging by the scapes and grazes on the used ones, not very long-lived, if sloping driveways or spoon drains are encountered regularly.
