This is a super simple mod to give your rear diffuser a nice little pop! All you have to do is take off your rear diffuser which takes about 5 minutes and is super simple. Then run down to your local auto parts store and grab the paint color you want to use I chose black. But before you paint you will want to sand down the diffuser with 480 grit first and finish up with 1000 grit. After that clean it up with acetone and you are ready to paint!
