This is a rear diffuser version that is also a bit more aggressive, much like the front and sides. It is extremely lightweight, and attaches directly to the rear fascia. This product will likely not work with the Mopar rear diffuser, but will work with dual exhaust and no exhaust cutout setups.
There is a new version of the diffuser, Diffuser Plus, and each fin is twice the width of the original, or 12mm wide. This is two sheets of Alumalite, bonded together. The screw holes will be to one side of each fin.
The fins are made of alumalite, are extremely durable, and attach to the back with mounting tape and screws. There is a hinge underneath to attach upwards to the existing undercarriage, and also screws into the fascia. *You will have to make holes in your fascia!
Drilling is not needed, the kit includes self tapping screws, and the fins are pre-drilled, so a simple screwdriver will be all that is needed for installation. The diffuser fins are made from 6 mm, gloss black alumalite. Double sided tape & screws will be included for mounting. This kit has been on Dartlene since 2015 without incident.
For a more professional installation, we recommend removing the adhesive, and applying a thin bead of black silicone. You can use dish soap and water to clean the overage, and this will dry incredibly solid on the car!
The standard version is 6mm thick, while the plus diffuser fins are 12mm thick. The screws do show, or you can use a small amount of liquid electrical tape (black) to cover the screws, as shown in these pics. The mounting hinge can be seen underneath:
These are made to order, and require painting, so delivery will be about a week out. These are all made by hand, and are available to order today, for $159.00, and the Diffuser Plus version is $219.00. Shipping is ~$10 to most of the US.
This includes 4 (or 5) fins, mounting screws and hinge, as well as double-sided tape for added strength. Black silicone is recommended (instead of the adhesive) for a more professional installation.
New in 2018, we now offer a 5th fin! The fifth fin goes underneath the license plate, so it is a bit shorter. This is an additional $45 for the Diffuser, and $65 for the Diffuser Plus version, pictured below:
