I daily drive my FL5 even though I have a bugeye Subaru. One thing I did not know about the FL5 is that it didn't have a spare tire. Thanks to original poster hhkb for his post, I was able to get my hands on the OEM Kit and Spare tire at my local dealership in SoCal. If you want to see the original post, please go here. https://www.civicxi.com/forum/threads/exploring-a-clean-fk8-spare-tire-kit-install-in-the-fl5.53627/

If you are wondering if the OEM FK8 Spare Tire works in the FL5. It does, with modifications and finessing the trunk floor mat.

Note: this installation is opposite to what some users have done in removing the 4 squares of foam. I will be "adding" foam and supporting stress areas in this install. I put several groceries in my trunk and would really like a planted flat surface.

Things you'll need to do:
Order the following parts from your local dealership. This will cost around $380 or less depending on your dealership. You do not want to have this shipped to your house. Save yourself the cost and pick it up. Note: The OEM box for these items is VEERRRRY bulky but will fit in your FL5 with seats down.

06421-TGH-A33ZA - FK8 Spare tire kit, includes the rim, FK8 floor board, scissor jack, scissor tools, FK8 tow hook, spare tire psi stickers and stickers for driver door jam as well
42751-CTL-039 - This is the continental tire
The dealership can install the tire to your spare for $30 or you can take it to any cheap tire shop and they do install only for $12, in my experience. (balancing is not necessary because you aren't supposed to drive beyond 40 mph with this spare anyways)

Amazon order:
-Quantity of 2 9"x6"x3" Yoga blocks
-Quantity of 1 2" Inch Thick Foam Yoga block to cut to pieces
-Goop trim glue

Various items and tools needed:
-Masking tape from harbor freight or anything similar
-Pair of scissors, screw driver, wire cutters & serrated knife

Step 1 - Remove your FL5 Tray cover and replace it with the new FK8 tray cover. Two screws under a cover at the holes

Step 2 - Remove your privacy retracting screen from the trunk

Step 3 - Cut your 2" yoga block using your serrated knife. You want to cut enough to add to the green areas in the first picture. It should boost each block to at least 5" in total. I wouldn't worry too much about how it looks, it will all be covered in the end. Add 2 strips of masking tape to test fit all the pieces. Adjust as needed.
>>Green indicates the need to add material to boost to 5"
>>Red indicates the need to create your own stack/block to support the added gap
>>Blue indicates an area where you can wedge the large Yoga blocks without modification

Step 4 - This is an optional but recommended step, create your own stack of blocks or a solid block to fill in the red squared areas. These are stress points that are empty and would benefit with support, otherwise you will feel like the board has gaps that can cave in.

Step 5 - Cut down the left flap board with wire cutters, use the adhesive side of masking or tape to pick up the dirt and debris

Step 6 - After test fitting the board and you are satisfied, remove and add 'Goop' to each addition. I used the same masking tape to hold it in place along with closing the board down so that it all stays in place. Give it time to dry.

Step 7 - Modifying the trunk mat requires your hands and scissors. You can use a heat gun if you would like, but I skipped on this and cut some corners, literally.
>>Red squares indicate areas where you'll want to invert with your hands
>>Teal indicate where you want to invert the orientation of the mat by reverse folding the mat with pressure
>>Red lines indicate where I cut off material or made cuts.

The result is a nice flat surface right from the trunk lock with the same benefit of the trunk tray mat. If you prefer to run it without the mat, it looks even better. My car is a daily, so I do not mind how this looks and would prefer coverage from dust and accidental spills.
