Why is it a must? What is the fascination with upgrading the brakes on the car? Especially since nobody here has driven it yet and has no idea how much it will take to fade the brakes.

Errrrrrm.... is it me or are those front hubs lifted straight from the Impreza and have holes for front driveshafts

Boosted 4WD 86 anyone? GT-486

AWD won't happen with the engine where it is unless they shove a diff in front of the engine

Yes that was the first thing I noticed lookin at those pictures! it's surprising if true. I would have expected the car to have its own knuckle design. I have no interest in 4wd but I wonder if greddy could have swapped them in from the Subaru for some reason.

Edit
You can clearly see it in this picture

Good article I thought, not edited together very well as lots of stuff gets repeated but there is some interesting insights.

Edit2
He goes on about how the struts are quite far inboard giving a high leverage ratio, if the hubs are lifted from the scoobie that could explain it as I imagine it has wider/different offset wheels which need to clear the struts.

It's not. That's been my point for awhile

It's only for looks at this point because it doesn't make much sense to use brakes designed for a car that's 500 pounds heavier with a 60/40 weight distribution. I think it would be wise to wait until someone can test a BBK with the proper rotor diameter and piston sizes, especially if looking to track the car.

This actually makes me wonder if the front hub design is similar to the rear hubs on 90's Nissans. If they're a bolt on design as opposed to a press in design, then the 5x114.3 hub swap that everyone is clamoring for should be pretty straightforward.

Looks like a bolt in wheel bearing to me

I pointed the Impreza front hubs out on the concept car (old thread somewhere on this forum) so i was totally surprised to see the hubs still from the impreza on the road car!

Im positive we'll see somebody do a total WRX Engine/Drivetrain swap shortly after the car is released meaning a Turbo'd 4WD GT86
