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.


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 :party0030:

I would be in for that

I don't understand what's all the whinning with the 5x100 bolt pattern.
Every freaking Rota wheel comes with that pattern and they
make knock-offs of every freaking wheel out there.
They have an amazing selection of wheels.

He never said that they were the only wheel, only that they had a lot of options for the bolt pattern.

I can't support a co. that can't have an individual thought and has to copy off of others hard work.

yep, i'm in the same boat as you. my MR2 has the weeniest brakes ever put on the SW20 chassis, yet with just some decent pads and fluid, it stops plenty hard enough. not sure why people are SO fascinated with putting the biggest brakes in the world on relatively light cars. and if i ever get it back on track and start experiencing fade (which i fully expect on the slicks with 2.5-3 times the horsepower), i'll step up to a more aggressive pad compound.

Jamal on motoiq brought up a good point...on the STI the brembos are on the rear side of the rotor and for the BRZ the calipers are on the front. So it's not going to be as straightforward of a swap as you think (if you want it to work correctly). I have other ideas, but still premature at this point.

When your rotors start turning blue, you might want to think about some ducting as well. :D

There doesn't seem to be anything preventing just swapping the front calipers left to right.

The issue is the piston sizes are staggered....so you'll end up with nasty pad wear if you swap left to right (which you have to do in order for the bleeder to be on top). Fine for "the look" but not worth it for me.

unless you have lots of money to throw away thats the only way to go for most people.
I have WAY better uses for the extra $1k-$2k I'll save purchasing
the Rotas vs the original brands.
I have no need for forged wheels so Rotas are the way to go.

besides if you have that much money there are plenty of wheel companies that will make you a custom set with ANY bolt pattern you
may need so I still don't understand the whine about the pattern.

haha, yes, blue would clash with my color scheme on the car... :D

I haven't messed with the STI calipers before, but some you can switch the transfer tubes and bleeder to fix that.

Well that does throw a wrench in the works. I suppose the blank bosses will need to be drilled and tapped then.

The sti calipers have internal transfers.

Tell me something I don't know :bellyroll:

You make it sound like forged wheels are the only light weight wheels out there that are right : That is incorrect

You act like ROTAs are lightwieght (well that isn't always the case)
