IAG site says this, but I'm with you. It sound like the rotors fit non Brembo packages. I guess you need to call and get a definitive answer.

DBA 5000 Series T3 Slotted 2 Piece Front Brake Rotor (Single) For 2002-14 Subaru WRX, 04-13 FXT, 13-20 BRZ / FR-S

and

The DBA 5000 Series is a lightweight 2 piece design that features a aluminum center hat and steel rotor. The 5000 series utilizes a High Carbon Alloyed Iron rotor with Thermal Stability Profiling allowing for constant heat cycles generated from "late braking" scenarios. weekend track race events. *Does not fit BRZ limited.

According to google they're only a little bit lighter than the oem pieces, but not sure if that means brembo or non-brembo. I have the latter, so anyone know if there is a weight reduction there? Are those 17 lb or is that for the brembo rotors?

326mm cast blank rotors for Brembo are 23 lb.
294mm cast blank rotors for base are 17 lb.

Cost for weight reduction of 2pc rotors for base brakes isn't compelling. They'll wear out not much slower than blank rotors, you barely lose any weight, and you're paying 5x more.


Finally overall, DBA 2pc solutions seem to be pretty inefficient with weight reduction.
- For example, the DBA 2pc for Brembo comes in at 20.3 lb, while Girodisc's comes in at 16.5 lb

Thanks, I figured. I was gonna combine it with lighter wheels for a significant weight drop per corner but only if it was 5lb+. From the sound of it it's not even 1 lb

I wonder if there is a heat dissipation advantage?

Apparently they overheat more cause of less metal for the heat to dissipate into, but maybe that's just conjecture

That's what you asked for.
