*If you choose to add the rear sparts with your diffuser, we need to know if you have or not the underbody spoiler kit. The shape of the rear spats will be different according to your application.

This piece is made to fit under the factory rear valence (Base or A-Spec) and will align and bolt with 2 holes under the rear bumper. You will only have to drill one additional small hole each sides in order to mount it properly (they won’t be visible if you remove it). Double sided tape will already be applied on the back of the fins so you just need to peel and sticks to prevent vibration and damaging the paint on your bumper. The CNC machined fins fits precisely over your factory valence. This is a must for a more aggressive look that flows with the style of the TLX.

What does w/aero or w/o aero kit mean?
The "aero add-on" refers to the underbody spoilers that may have been added to your vehicle at the time of purchase. Some TLX models come with this option, while others do not. Refer to the photo below that illustrates what the w/aero package looks like.

*Please note that we do not sell the aero package on our website, and it is not included with the product you purchase. If your vehicle does not have the aero kit, please select only our products with the w/o aero option.

Not as tall as anticipated
Color: Black, Size: Wheel-6 Panel
Definitely not 6 feet tall, more like 5 1/2. Very sturdy and the fabric is thick. Works well for what we're using it for.

Nice room divider!
Color: White, Size: 8 Panel
The white panels are a nice off-white color. shipped in perfect condition. Already assembled so set up was quick. We use them to separate a photo studio from the main entry. Easily covers a 6 Ft. opening to the room. They are a woven material with wood colored sticks to support the weave. They are about 6 Ft. tall at the top of the curved section but less at the hinged sections. Light and easy to set up and take down. We are straddling two different floors so the extended legs at the bottom make this easy. Not sure how to clean them but they look great so far!

Instant Privacy
Color: Beige, Size: 8 Panel
Bought this to separate a ground level living area used as an office. Works well to cover visual clutter; allows a clean look when entering the front door. Comes fully assembled. Hinges are sturdy enough, as long as the panels aren’t stretched too far; have to allow some bend between them. For the price point, quality and functionality are satisfactory.
