GR86/BRZ Track Comparison (Japanese)

Why?
The springs primarily have to deal with sprung mass (body), especially when it comes to handling (as opposed to handling bumps).
We don't change suspension spring rates when we change wheels/brakes, right?

I wouldn't spend too much time drawing conclusions based on the lap times mentioned in early "shallow" reviews.

If the same driver was only doing a few laps in these cars and on a given day, the difference could just be due to
a) the driver progressively adjusting to the track, power level and grip
b) weather conditions changing throughout the day
c) tire wear and heat throughout the day (I believe the cars were shared between many people?)

Pretty sure in apples-to-apples comparison the difference in lap times between same-transmission cars
will be negligible for most beginner-to-intermediate track drivers.

i'm just saying if toyota/subaru never told the public, the journalists wouldn't even know when they drive the car.

the biggest difference will come from the spring/damper and roll bar package. the fact that the translation doesn't even explain why the changed the hub and rear bar mount location is already suspicious.

Looks like the early GR86 prototypes had aluminum knuckles and chassis mounted ARBs.

They do indeed!

So it seems like in a last ditch effort to please their boss, the Toyota team have raided the spare parts department and fitted the old suspension parts from the gen 1 to 'differentiate' the driving experience

If this is true, this could indicate that coilovers would swap between generations.

Often (not all the time, and maybe not even the majority of sports cars) cars move to aluminum suspension parts for fuel economy and take advantage of the lower unsprung weight to reduce spring rates for a more comfortable ride.

As you say, this is primarily for handling bumps, not handling...

Fair enough, sometimes cars are designed for comfort, not handling

That being said, I reckon different knuckle weight affects the performance of dampers more than it affects the performance of springs?

I'm genuinely surprised about the suspension tuning of the 86. I'd have thought Toyota learned something from the pushback about the Supra's random bump oversteer (something a lot of people, including Keiichi Tsuchiya and some other prominent YouTubers complained about).

Between that and slight chassis differences, it seems like the BRZ is slated to be the more linear, predictable car.

I may very well end up getting the BRZ over the 86 for this upcoming gen.

5 minutes in

It actually sounds less genuine than a video game

I think it’s impossible to judge the sound from a video. You’re missing a ton of frequencies and between the mic, encoding on the camera, and the device you watch on, the EQ is probably all over the place. If they actually use noise cancellation to remove unwanted frequencies it may turn out very interesting. Either way I’ll reserve my judgement until I drive it. Worst case scenario you turn it off.

Sorry if it has been confirmed somewhere. I not sure if the auto-translated videos seem to show that it's noise cancellation (which would be nice) or just dumb old artificial engine noise. Or.... (this would be interesting) a mic to record and then reproduce (with the necessary frequencies amplified/suppressed) the sound in the cabin, kind like a modern interpretation of the sound pipe. Hmmmm.....

[Yoshoobaroo]

An autotranslate bit from one video is very thin evidence to go on, it could very well be regular old fake sound.

Also interesting how this ties into the sound system. It’s probably not the headunit doing it since the Japanese cars all have aftermarket units installed.

I hope the english-speaking car reviewers get to the bottom of this and more! Can't wait....

It depends on the camera. They're using Sony Action Cams and those little things have surpriaingly good mics when they're not shoved into a sealed case
