GR Monoblock Brake Kit

Also, would they fit with the stock wheels on the premium trim?

they have these weird manual only disclaimers on a lot of the parts for some odd reason, and I imagine it's because they didn't bother testing them on it vs the manual, but there should be zero reason why you cant on the majority of them. One I can think of that does not fit is the underbracing and that is actually due to the AT being different dimensions iirc.

Yes, the BBK fits the Premium wheels (not sure on the base).

Talked to a Subaru development driver about the Subaru Performance Pack BBK for this model year. Apparently, there are huge issues with ABS calibration. Previous gen cars had ABS calibrated differently for the BBK.

interesting ^

I remember reading that even the old system on the first gen could do weird things brake wise with EBD (if not disabled), wonder if that's what he was referring to.

Are you planning on getting these GR brakes?

That's likely not aimed at me, but I'm planning on it personally if the performance pack doesn't come out prior.

Nice, as much as I want a BBK, I'm just going to paint the stocks calipers, I just want the looks so I don't think it'd worth it for me as someone whos just going to DD this car lol

I only DD it as well, but I want as close to the full catalog on the car as possible lol.

But it's $3500, so it will be a while before I get there.

The parts on RR racing for wilwood calipers are close to 2k for the set. Pretty decent.

I was thinking I would do that too, just from a DD standpoint. Are you going to use red VHT spray paint, with a clear coat VHT as well?

I'm not sure yet, I don't have my car yet and most likely will have my sister's boyfriend help me out as he knows a lot of about this stuff.

there are def much more reasonable options if one just wants an effective BBK. I have a Wilwood kit on my Supra and my friend has them on her ND Miata (they were not expensive relatively speaking).

I was wondering about ABS. On the one hand, you'd think that lockup would be lockup, who cares what combination of braking & traction caused it? On the other hand, the system has to react dynamically, so if the brakes are more aggressive than standard, the system might continually overapply pressure and keep initiating lockup to the point that the ABS function essentially no longer works.

I think the idea is that ABS is unclear on how far it needs to release the pressure in the line to allow for slip. Since there's a larger volume of fluid in monoblocks, it might release it too car and create too much slip.
