2022 Subaru WRX Spare Tire?

Hi,

I just got a 2022 Subaru WRX and I have been trying to figure out what to do about the spare tire issue.

I have done some research and so far the only solution that I have been able to find is using a spare tire from a 2018 or older Subaru WRX or STI and retro fitting it.

I tried searching online to see if any companies have come out with a spare tire kit for the 2022 Subaru WRX and I was unable to find anything reputable.

I wanted to know if there are any recommended companies that have a spare tire kit for 2022 Subaru WRX?

If there are no reputable companies to purchase a 2022 Subaru WRX spare tire kit. What is the best way about on getting a 2018 or older Subaru WRX/STI spare tire and how to go about retrofitting it with the foam piece?

I'm sure the 30lbs they save helps them edge a few fractions of a percentage towards some goal. It drives me insane.

I'd rather drive 30 miles to a tire shop on a full size spare than on a god damned donut that's going to explode if you hit a bump too hard.

The other one that drives me absolutely bonkers is when they use a donut with a load rating so low that even blasted to 80+psi the weight of the vehicle flattens it. Looking at you jeep.

I can't access the australian subaru parts site. Wayback machine or vpn might work. This is another interesting one:


World car is just a ford mktg gimmick, every car has some changes between countries & subaru has made r160 lsds before so it wouldn't be much effort for them.

I'm not sure what this has to do with anything. It's a well known fact that the 2002-2007 USDM WRXs and Forester XTs came with a viscous rear LSD.

I disagree. I can understand why this isn't well understood outside the manufacturing sphere, but as someone who spent 15 years in engineering in (primarily) Aerospace and Automotive manufacturing, there is MASSIVE financial value in consolidated supply lines and reduced SOP complexity for mass-produced cars. The value is monumental from an operations and quality control perspective as well. It isn't just about "how easy is it to design a new product." @XJman also works in automotive manufacturing and will very likely have the same input.

There was some press release or something that stated the Australian vehicles did have a torsen rear diff. I have never seen anything to dispute it.

I personally doubt they would. Usually component assembly of that nature is pretty automated and it would cost a fortune (read increase overhead enough they loose a fraction of a percent in profit) to have a line dedicated to a small production. The US is still the largest market by a fair margin.

True, they could be selling old inventory, but I still find it unlikely.

The issue with viscous LSDs is that they have a shelf life. The viscous silicone fluid does degrade over time. It's accelerated with use, but even sitting on a shelf the LSD will become less effective.

As I recall (and that requires heavy fact checking because my memory sucks lately), there was a Torsen rear LSD available for JDM WRXs in the late 90s and early 2000s. Keep in mind that the STI used to run the R160 rear in the Version 6 and earlier, so it's most likely a carry-over from that generation.

Otherwise the USDM WRX only ever had the viscous rear LSD for 6 years and then an open rear differential since VDC/TC appeared in 2008.

I tried to order a spare the day I picked up my WRX. Found out it is not allowed in the U.S.A.. I purchased a spare tire from Modern Spare dot com. The tire is rated for 80 MPH, safe to mount on the front of the car, and it is a half inch taller than the spare you can't get from Subaru (bringing it within two tenths of an inch of the height of the OEM tire).

After purchasing my spare tire from Modern Spare dot com I noticed the size of the center hub hole on the spare (72.6mm). With the hubs on the WRX being 56.1mm. I picked up a box of 4 Hub centering rings from Amazon. Should I ever have to use the spare. I didn't want any problems with the wheel not being center.

subaru got rid of spare tire for 22. Just pump n tire goop now. It still has spare tire well but not deep enough for full size tire.
I tried that. The tub of goop is well over $100, plus Subaru Service wanted to charge me another $230 for replacing the TPMS which they said the goop ruined. Add the cost of the patch and it's something like $500 every time you get a nail? It sucks
