Added a Spare to my 2024 Performance Z

[Shuino]

Well since the new Z does not have a spare, and it has the room, I figured why not.

I ended up buying two things from eBay. A compact spare from a 2015 Q50 (18x4) and the jack/tools from a 370Z. (Spent around ~$190)

Next, lets get into the back of the Z. First we have the Rear mat.

We get that out of the way, and we have the under-liner.

Now that we got that removed, we go down one more level, and we hit a plastic insert.

Finally, we are at the the bottom and we can see our foam inserts.

The entire middle foam insert was removed, and I'm in business with a spare tire. The jack, tools, and tow hook all fit into the OEM foams.

I ended up stuffing some old towels around the tire just to make sure it does not slide/move around. The plastic insert, under-liner, and rear mat fit back on top without any bulging or fitment issues. For under $200 bucks I'd say it was worth the addition.

So did you have to remove the sub? It looks like it is still in there.
Nice job!

Sub fits perfectly right into the spare tire which was nice, I believe the 370Z was the same way, so I was hoping to get the same fitment!

It was actually designed to fit in the spare.

That was genius!
Great job

Certainly a pretty great engineering idea. I do wonder if it has any effect on how it sounds? Sitting inside a wheel hub vs sitting in all foam. (Not that I particularly care, but would be interesting to know)

I did the same thing with my Z Nismo. Except I bought the 20" EZ Spare, because I wanted to make sure that it cleared the larger front caliper, and the outside diameter of the tire they use is pretty much exact to the stock tire's diameter. I also bought the Jack/handle/wrench etc. from ebay for about $150 from a 370Z, it all looks brand new too!.
I feel like the stereo sounds better with the tire, that was a nice surprise. It seems to have a tighter bass with a little more punch to it! That was a nice side effect of the change. I guess the foam surrounding it was absorbing the sound and muffling it, so now it sounds a little "higher end".

I'm pretty sure anything would make that sound system sound better. It's so bad as it is...

MY EZ spare in the trunk with the Bose sitting on the original location.

My jack and tools are in the cloth bags tucked in beside the spare, and I did not reinstall any of the foam panels. I normally just have the carpet laying over the spare/Bose as it seems to allow for better/more sound from the Bose. Note: I have never put any luggage/packages in the rear...if I did I would just reinstall the fiber board panel as needed.

This has been on my list of things to do and finally I got to it. These posts have been a huge help in figuring out what I needed to get. I got a 2015 370Z space saver spare size T145/70R18 from EBAY for 180.00 and will be adding that to my 2024 Performance Z that I bought in October. I looked at the EZ Spare and it was over 300.00 so I decided based on scouring this and other threads to try ebay. I also sourced a jack and tools from amazon with a bag that should fit nicely in the rear like yours did. So far I love the car and have had it since 10-18-2024 and just now have 1000 miles on it. I am hoping I got the correct wheel and as far as I know I did. I expect the Bose to fit the same as yours did and I'll post again after I get it checked and on/in the Z.

The 2015 370Z T145-70R18 space saver spare fit perfectly and actually replaced the thing that was holding the sub-woofer. The jack and tools were placed back in the spots that they would have been in. I also mounted the spare on the front and rear to make sure it would spin freely with no interference. The lug nuts worked OK as well. Here are before and after pictures. Also notice there is plenty of clearance in the spare/caliper on both wheels. The enclosure that held the speaker just lifts out and will be stored somewhere.

Ordered the "modern spare" spare tire and jack kit for my 24 Performance.

M speed rated tire on a 19" aluminum wheel.

I took out the passenger side styrofoam so that I could fit the jack, tools and still fit the pump and fix a flat that came with the car making a roadside repair of two tires possible.

Does the Modern Spare use standard Nissan shank lug nuts? Does the spare change the way the subwoofer sounds?

I added a Modern Spare to my Z and can now definitively state that the subwoofer sounds an order of magnitude better mounted inside a spare than it did surrounded by foam. I also did mount the spare wheel on top of a sound deadening pad for additional insulation from unwanted noise.
