DIY: Installing OEM Spoiler for Pre-Facelift & Facelift (Excl 2020) Hatch Mirage

[Tsukinoma]

Hi all,

Backstory:

Australian Base Mirage's (ES) don't come included with the OEM spoiler, and to be honest, it doesn't look as good without it, so I decided to add one.
This is where I purchased mine: https://www.ebay.com.au/itm/MITSUBIS...10cc%7Ciid%3A1

Compatibility:

For those wondering if 2013-16 pre-facelift OEM spoiler fits onto the 2017-19 facelift mirage, Yes it does. I had posted a query a while back but no one had tested it. So I took the liberty of finding out myself. Although MetroMPG mentioned that "the difference was a slight change in the angle of the 2017+ spoiler for drag reduction".

The boot lid between an installed spoiler from factory and non installed is drastically different but is still doable to install a spoiler onto the mirage.



Guide:

Warning: Should you go ahead with this DIY, please note that I am not liable for any damages you may cause to your mirage. Thanks for understanding.

Issues:

• Water leaking through the interior access may possibly be an issue. Will update
• You will be drilling 2 holes into your boot.
• You will lose windscreen cleaner jet.

(Please check Imperial Measurements)

So here are the things you require:

• OEM Spoiler
• Tail Light (If your spoiler doesn't come with one)
  
• Optional: Spanner
• Optional: Ratchet Spanner
  
• Drill
• 3mm Drill Bit
• 6mm Drill Bit
  
• Optional: Your pick of rust protection topcoat
• Optional: Touch up paint
  
• 2x 5mm M6 (1/4") Hex Head Bolt
• 2x 5mm M6 (1/4") Hex Head Bolt
• 2x M6 (1/4") Nut
• Optional: 4x Nylon or Rubber Washer M6 (1/4")
• 2x M8 (5/16") Flat Washer
  

First thing, open up your boot and remove the plastic cover to access 3rd light.



For the Rear Brake Light, there should be 4 clips, 2 on each side you should be able to just push them and remove the light from the boot out the other side. Unplug the cable as well.



Now for the hardest bit, you will need to remove the windshield wiper jet since it will not fit with the spoiler on. You can do this by getting scissors or needle-nose pliers and pinching the 2 points which hold it in. Good luck! (Thanks to Jeff for his help on how to remove and my chicken for motivating me to not give up)



Once you removed the brake light and the jet you are ready to prep the spoiler!

For the spoiler, since the boot design is different for a made to go with spoiler boot panel you will have to make some alterations. For the spoiler, there will be 4 points which plug into holes on a spoiler boot lid. Grab your wire cutters and go at them removing all four. (Image only shows 2 out of 4)



Once you have finished prepping the surface, whip out thy drill with 3mm and drill holes for both sides on the indentations shown beneath, after the hole is created, swap to a 6mm and enlarge the hole. Once done, test fit your spoiler with the holes to make sure the hole aligns.



Optional: Use your rust protection and touch up paint if you choose to do so on your new holes. I chose to do rust protection but not touch up since no one will see it anyways

Now, if you spoiler comes with adhesive for the corner mounts, prep the boot surface so it adheres properly. Remove one side of the tape backing and attach to the boot aligned with the hole. Remove the other sides backing and attach to the boot aligning it with the hole again.

Next, attach your 2x 10mm M6 bolts with nylon washer onto the outer threads. The configuration is shown below. (Note: The bolt in the image is longer than needed)



Now to attach the M8 Flat washer, M6 Nylon washer and M6 nut onto the inner bolt. ( I recommend doing this since you have lost the 4 extra mounting points which attach to the boot, this will give more stability for the spoiler.) The configuration is shown below.
(Note: The bolt in the image is longer than needed)



Replace the plastic backing over the interior access panel.
Test the light by pressing on the brakes (Car On or Off doesn't matter)

Congrats you now have a rear OEM spoiler on your mirage!

Note: for where the original brake lights used to exist, I am considering 3d printing a plate to cover it. Let me know what you guys think.
