How To Install 2024-2025 Mustang RTR Rear Spoiler

RTR designed the decklid spoiler using OEM CAD data to ensure a seamless fit and installation. RTR constructed the decklid spoiler from durable, injection-molded ASA plastic to withstand the test of time. To further increase durability and UV resistance, automotive-grade satin black paint has been used over top. Installation is a breeze, as the RTR decklid spoiler is a direct replacement for the spoiler, eliminating the need for complex modifications. Fully compatible with a backup camera, so you retain all of your safety features. Simply remove the factory spoiler and install the RTR decklid spoiler to transform the appearance of your S650 Ford Mustang.

Installation Instructions

Step 1: Remove & Transfer Reverse Camera

• With the OEM spoiler module removed from the car, loosen and remove the (2) T15 Torx screws securing the camera hold-down bracket.
• Remove the camera. Take this time to wipe down the camera as needed.
• Place the RTR spoiler on your workbench and install (2) of the provided speed clips for the camera hold-down screws.
• Situate the camera in place followed by the RTR supplied bracket.
• The camera connector will face away from the RTR logo.
• Install the supplied T20 Torx screws to secure the camera. 

Step 2: Transfer Factory Hardware To RTR Spoiler

• Working from left to right on the OEM spoiler, remove and transfer the hardware one at a time over to the RTR spoiler.
• To remove the speed nuts, you may have to pry up on the keeper tab. 
• If the speed nut isn't secure once on the RTR spoiler, remove it and push down on the tab and reinstall it.
• If the T bolts are difficult to remove, a very light tap of the hammer will dislodge them.
• Continue working untill all of the hardware has been transferred to the RTR spoiler. 

Step 3: Install RTR Spoiler

• If you have not already done so, take this time to ensure that the top of the trunk lid has been thoroughly cleaned and old adhesive has been removed.
• Wipe this area with a microfiber towel and prep spray.
• Dog ear the backing of the double-sided tape on each end.
• Hold the spoiler near the trunk lid and reconnect the rear camera.
• Insert the harness into the slots on the spoiler.
• Align the T bolts with the holes in the trunk lid and slide the spoiler into place. Open the trunk lid and hold the spoiler in place while you do this. 
• Reinstall the OEM nuts, run them down until they barely touch the trunk lid. 
• Reinstall the (4) 7mm screws and run them down until they also barely touch.  
• The outward 10mm bolts will NOT be reused. 
• Lower the trunk lid and remove the backing of the double-sided tape. 
• Firmly press onto the leading edge of the spoiler for a minimum of 30 seconds to achieve proper adhesion. 

Step 4: Reinstall Trunk Components

• Open the trunk lid and torque the nuts to 49 lb-in and the screws to 22 lb-in.
• Reinstall the outward grommets followed by the trim panel and push pins. 
• Reinstall the bumpers and latch cover.
• Finally reposition the emergency release handle into its slot on the trim panel. After this you are good to go!
