How many parts are transferable from 2013 to 2023?
 

As the title says, how many parts are transferable from 2013 to 2023? I was entertaining an option of moving to the latest generation BRZ/GR86, but wondering what (if anything) I'd be able to simply swap over. Anybody know some items, speaking generally?

Define "parts".

The gas in the tank, transmission, seats all swap over.

Pretty sure coilovers, suspension control arms, headers. Brake kits can swap over to GR86 but not 23+ BRZ (because of aluminum knuckles). I am sure there is more.

Probably closer to categories of parts:
- wheels
- coilovers
- sway bars
- braces
- pulley wheels
- transmission parts
- brakes
- etc.

Wheels: no, they switched to a 5x114.3 bolt pattern
Coilovers: yes, but they may not be “balanced” correctly for the new Gen.
Sway bars: yes
Braces: maybe, the 2nd gen uses a new front brace style that may not be compatible with aftermarket front braces. Everywhere else, braces should fit.
Pulley wheels: maybe, but the only aftermarket pulley I’d ever rock is the fluidampr which I’m 90% sure fits.
Transmission parts: I believe all bushings should be similar on the new gen but I am unsure
Brakes: yes they should be transferable but I know the 22 BRZ may have BBK caliper fitment issues due to the aluminum knuckles.
Etc: seats are transferable

They didn't

Dang it, thought for sure they had! That’s a good thing I guess

A few bolts & screws too.

i'm pretty sure the fuses swap as well.

Battery.

Def not a good thing.

5x114 has a much better wheel selection and range of offsets.

On topic, I have 2nd gen 86 door stoppers on my 2013 and my doors don't slam themselves on my shins any longer. Makes getting out of a bucket seat much easier.

Maybe you're being sarcastic (this is the internet) but gonna give the benefit of the doubt here - I have these, any idea whether these transfer?

STI Steering Rack Hardware (much longer bolts, nuts, subframe fills/spacers)
STI Steering Rack Bushings
STI Rear Subframe Bolts

Strongly leaning towards all of those parts fitting, but it’s something you’ll need to confirm for us :)
