Shout out to hhkb for their post on installing the FK8 spare kit in an FL5. This post is on my experience installing this kit. I ordered the parts (06421-TGH-A33ZA and 42751-CTL-039) from a local Honda dealership in Houston. Total came to $349 ($378 after taxes). A local NTB mounted the tire free of charge.

It took a week for the parts to arrive at the dealer (no issue), but about 30 min for the guy to find the parts. The box for the spare kit was beat to sh*t and it turns out the lug wrench was missing. I wrongly assumed the parts would fit into the CTR but the box was HUGE. I had to remove all the parts and place into trunk individually. The jack was loose in the box and I am certain I didn’t leave the lug wrench on the ground. If you order a kit, consider picking it up in an SUV or truck. Removing the parts on site might still be a good idea to confirm nothing is missing before leaving the dealership. Rather than deal with the missing wrench, I went ahead and ordered a lug wrench from an online Honda parts store that specifically listed the FL5 for fitment (89211-SE3-003; note: FK8 is not listed under vehicle fitment).


See hhkb for images related to removing the stock trunk floor. As indicated by hhkb, 4 short rubber pieces need to be removed in order for the new floor to lie flat.

The spare fits in the trunk fairly well. I saw one video on YT where the guy may have had the mounting clamp facing the wrong way (the molded tool tray is recessed on the bottom to account for the screw height (more on the tool tray below).

The molded tool tray is very nice and fits the spare wheel fine but has two problems for the FL5. First, the tray sits well above the rim thereby preventing the floor from lying flat over the spare. Second, the FK8 molded tray tool does not include a space for the jack. I assume this is because the FK8 has a storage compartment that the FL5 (in the US) does not have?

I took the molded tool tray from my 2024 Civic Sport Touring (that has a space for the jack) and found that it fits pretty well, a little loose on the sides but does not prevent with the floor lying flat over the spare. I modified the tray to fit the longer tow hook for the FL5. It also has molds for the lug wrench and jack handle under the jack. I have ordered a replacement tool tray for my Civic Sport Touring (84545-T43-K00).

Here is the floor without and with a cargo tray. The floor seems to fit well. I am keeping the original floor in case future solutions utilize the original floor, which has a much thicker underside. The Civic cargo tray still fits but not as well as before (no I did not get the mat with the TR logo).

Now, having done all this, I should probably confirm that the spare actually fits on the rear. It is my understanding that the spare will not fit over the front breaks and it is not ideal to run a spare on the front of the CTR. I have seen people complain that if the front tire needs replacing, changing two tires is a deal breaker. In my opinion, once you are changing one tire you are already having a bad day and its fairly trivial to swap a good wheel to the front if necessary. At least this gives you more options than calling for help or losing your trunk to a full size wheel. Hope this is helpful.

I bought an ebay spare and found I needed a hub spacer on the front for brake clearance. Amazon had a 5mm thick spacer, which works great and leaves enough stud threads to secure the lugnuts.

Do you have the link to that spacer on Amazon?

Same here. It's a big box.
As a bonus, the dealer mounted the tire for me for free.

Saw from another video that running the spare on the front will mess with the limited slip. Best to move a rear tire up if you get a front flat.

The 135/70 has a closer diameter to our stock size than the 125/70, so just wondering if you think a wider tire would still fit flat?

So I did the 135/70-18 which almost the same exact size as OEM diameter. Not sure if it made it too wide to sit flush, but it's a bit lumpy on the sides. So probably 125/70 is the way to go. I did lose a bit of height as well, but would rather have the spare in there.

Note: Type R Trunk cover does not fit nicely any longer either. as the trunk is now elevated vs going down.
