This is the rear diffuser I have been waiting for. I have a Rallye Armor Mud Flaps and usually rear diffusers messes up with this mud flaps. This recent rear diffuser is very Ideal. It fits flush. With all accessories that needed some double sided tape install I would always use my 3M VHB double sided tape and 3M Adhesive Promoter instead of the any double sided tape sent by any seller. This item is highly recommended. It is not painted but you can just ceramic coat it and its good to go. Buy while supply lasts.
