GR86 Real World Road Tests & Reviews

IIRC correctly it was specifically mentioned in the Japanese comparison thread that the rear subframe was less tight to the body to encourage toe-out under compression. The toe arms are mounted to the subframe so letting the subframe rotate around the Z axis could provide a similar effect without having to make different toe arm assemblies for the Toyota.

I’m so curious to see the front suspension of those cars they had.

They are effectively reviewing the 86/BRZ 1st gen with headers, e85 and a tune.

I think its fair to say that the proper amount of torque and power they are talking about is just as readily apparent for all those who would of upgraded their cars.

In the Throttle House video it seems that good tires would make up the difference on the track considering a 1G had a better time. The camera man has an FRS and ran a "low 1:15" compared to the 1:15.90 of the 2G. I would have liked to see them do a drag race between the two.

really comparing apples to oranges.

i would like to see lap times from pobst in showroom spec (factory tires) on a real race track. i'm not a fan of trying to equalize the cars with the same tire spec.

all the arms are mounted to the subframe, so letting it moves provides zero change in suspention geometry, just where the suspention is under the car. the thrust axis would move around, but not geometry under load.

I am now more confused than ever. How hard is it for the manufacturers to simply tell you what they are selling?



Thanks to Paul at TFL for getting the info.

However, after some googling, the 2013 FR-S runs 0-60 in 6.2 according to many tests.
Has anyone tested the 1/4 mile?

Btw, please don't start a MK1 MK2 trend.
I think it should either be ZN6 vs ZN8,
or FT86 (FR-S/BRZ/GT86/86) vs GR86 (GR86/BRZ) Edit... Wait that doesn't work.

Toyota quoted something like 7.3 seconds for the old one. Magazine tests got that down to around 6.2 seconds with an aggressive launch.

Toyota is quoting 6.1 seconds for this new one. Magazines should be able to get that down to the mid 5’s or better with a similarly aggressive launch. Jason Camissa has already said he’s done an “easy” 5.6 seconds with the new one.

Fair, the geometry doesn’t technically change, it’s the thrust axis. It can provide a similar corner entry effect though, provoking the car to step out.

Seems a bit misleading if they’re planning to change it still, since the sway bar mounting and subframe bushings determine the toe out on compression that they wanted to create, to mimic the Supra suspension behaviour. That’s been pretty controversial on the Supra.

GR86:



GR86 at us press event:



BRZ:


Edit: Just had a thought. The BRZ seems to be significantly ahead of the Toyota in the release schedule, The BRZ must be finalized by now. Could these be early production BRZs that were modified to match the toyota spec and cosmetics *but not 100%*? Some parts like the new subframe may not be ready, so the BRZ version was used. Do any of the videos from yesterday show the front knuckle? I haven’t seen any.

Edit2: this could explain the absence of a Neptune car at the event too.

Follow up:

I did a quick scrub on YouTube and managed to find a shot where the top of the front knuckle peeks above the brake disc. It was confirmed further in the thread these are aluminum.



Brz knuckle for reference:

I just don't see any way is a stock 86 beating a stock gr86.

I think that what the journalists said was the upgrade was pretty clear. They drove them back to back (the TRD updated version too).

We're very lucky that both the BRZ/86, and the new Nissan Z, are being introduced. It might be 'last call' for these kinds of cars. Let's enjoy them while they're here. Once they're gone, they won't be back.

Also the new integra coming out!

All of this strangeness and we dont even know what size swaybars those cars were running!

Saved?

Matt Farah found his footage, I guess.

Tires affect the lap times more than almost anything else.
Almost nobody does time trials on stock tires, and only "spec" classes designed to be beginner friendly run 215s.
Why should results of performance tests depend on what comes from the factory? What if I buy a car in winter and it comes on winter tires?

On our cars, the tires only really matter for the first few feet of a drag race. In the TH video, the 2nd gen was clearly pulling away more and more as the speed increased.

i get that tires impact lap times the most, but the modifications can be endless.

but i still prefer to see lap times with 0 modifications/straight in showroom spec. the data is too messy when you start modifying the car.
