Does an after market black grille come with the R emblem attachment or do I have to creatively build a bracket for it?

 

You have to get creative...
It's pretty easy though. Just remove the clip that attaches the R to the OEM grill so the back of the emblem is flat. Then hot glue away once you have the R where you want it to be...
Here's mine...

 

looks cool, thanks.. Did you replace your front bumper? Or does it have splitters?

 

Nope, That's the OEM front bumper with the winglets from the factory S60R aero kit.
