Anyone experienced or dealt with installing vis spoon style diffuser? If so, any modification needed like drilling and trimming required? Thinking about picking one up from a local retailer.

 

Have to drill 2 small holes in each bottom sides of the bumper. You will not be able to tell the holes are there unless your under the car. The rest you use brackets that come with the diffuser. Or make your own.

 

Also, make sure you get or make the brackets for the attachment points near the diff.
