Any one?

Yes all WRX front rotors should work, or at least 2002-2007 will. All the same rotor, 294mm vented. (~11.4")

Yes the 98-01 RS wheels will clear the calipers, with no spacers. They're JDM STi wheels and were designed for this purpose.


Great thread, I'll Stick it.

So i just became the proud owner of these babies.

So any year WRX rotors should work with them... I'm guessing that any year WRX pads will too? OR do i need to get the 2006/07?

Also, is it necessary to have the backing plate?

Does anyone have the part numbers for the black calipers? I ordered the red ones and got them in today, but just really want black. Im not gonna paint calipers black when theyre factory painted already. If not im gonna just stick with the red ones.

Blacks have some fitment issues in the back. I suggest you stick with red or paint the red ones black.

Honestly i'm not even sure they will send you black anymore unless you buy used from japan.

True, the only ones in Subaru's warehouse inventory in the US are the '06-'07 red ones. The JDM black ones were never sold here so there's no part number. If you paint the red ones black, you can get "SUBARU" stickers from Paranoid Fabrications to make them look factory. They have the stickers in a couple different colors.

I ran into an issue with the parking brake when I swapped over to '06 4pot/2pots. I also swapped over to complete '06 WRX rear hubs as well so this may or may not apply to all cases. I used the '06 wrx parking brake cables and had to purchase a the splitter (or whatever it is called - place where cable splits from one to two to go to each corner. The '06 WRX one is slightly longer than the 2.5RS one.

Thought some people might be interested. As far as cost, I spent just under $1500 for hubs, calipers, upgraded and stock pads, upgraded and stock rotors, upgraded and stock lines, and motul RBF600 brake fluid.
