RLCA length was the same when measured with a tape measure.

The Limited trim's wider wheels would... push track width wider as well.

2022 BRZ Limited 18x7.5 wheels should clear 17-20 PP brakes without issue.

Needs a 5mm spacer to clear the CSG V2 Brembo BM4 caliper.

Please add more details to this thread!

Yes, but some wheel/tire combos that have no issues on 1st gens might have issues in the rear on 2nd gen, see the thread referenced above.

They're 7.5" wide, same as Performance Package on '17-'20's though?

Subaru Part catalog confirms same RUCA as previous gen.

Catalog also shows that the rear knuckle and rear subframe are specific to the new gen, but the Wheel Bearing assembly is the same. I'm assuming that the track width difference is coming from either or both of those.

Almost makes me think the changes to the rear may have affected camber gain or other alignment geometry, which may have an effect on the wheel fitment difference @trippinbillies40 is reporting. But its just a theory at this point

Some ACS footage showing a clean lap, as well as comparisons to the 1st gen car in LONG straights.

So Mike, 1st Gen with header and Zach tune compared to stock Gen 2 as far as performance?

Roughly yes. Not quite 1:1 as the powerbands wont be identical, but pretty darn close.

How much Ethereum do you want to send me a CSG goodie bag?

hey mike, i dont think i've seen you do a brain dump of your thoughts on the 2nd gen yet. specifically, in stock trim and how it compares with the 1st gen.

I haven't. Still gathering my thoughts and need to spend more time in the car.

Any updates on the oil temp situation?

I presume you've switched to 5w-30 oil?
The car still only has the OEM oil cooler?
How much cooldown does the engine require throughout a typical track session, compared to e.g. tires and brakes?
Do you plan to keep the OEM oil cooler, or install a separate radiator?

No updates.

Still on factory oil.

Still on the factory oil heat exchanger

Zero additional cooldown needed.

Unknown, as I don't know what's needed.


If you'd like to fund the R&D, I can probably get all of this done quickly, within a week. I'd need to hire a CANBUS expert to sniff and identify the relevant channels, as well as a fabricator to figure out an oil-air mounting solution, factory cooler delete, thermostatic plate solution, and line routing. I'm sure some time can be saved by having new existing GReddy and Jackson oil cooler kits on hand, but that alone is already easily a $5000 bill.

Remember, I have to work a job too, and only have so much resources to put towards this car.

there's no oil and pressure data on the dash? is there factory oil temp sensor?

does ecutek from 13-17 work, or does the ecu need to be jailbroken to access the ecu tables?

Only temp, and it's one bar that reads from 120F to 340F, so the resolution is quite garbage. Once we have a digital reading to equate to positions on the bar, it'll be more useful, but at the moment, nothing.


Ecutek doesn't even recognize the ECU. None of my existing hardware reads any data out of the ECU other than base channels.
