What size brake rotor does the 4-pots Impreza WRX brake caliper use? Not the Brembo brakes? Are the around 11.4-11.6 inches?

Where is the cheapest place online to get the Subaru 4-Pot brake calipers?

Which 4 pot?
JDM WRX
22B
WRX TR

Cheapest places vary... usually a take off from a WRX owner is the cheapest place.

Non-Brembo, I think I'm talking about the Red ones they sell on www.subaruwrxparts.com (http://www.subaruwrxparts.com)

I wasn't aware that there were any differences in the calipers. Honestly I don't care which they are as long as they fit, reliable and cheap.

All 4-pots use the same rotor, a standard WRX front rotor (same as the factory 2-pots on the WRX's).

Any front rotor for a 2002-2007 WRX will work.

Well it looks like I share the same front rotors as the 2002-2005 WRX, looks like I can get the Calipers without changing my rotors. Now where to get them is another story altogether.

More than I care to bother with, pretty much everything needs changing when going with 2 pot rears, rotors, pads, back plate, that's something I'll take care of much later.

2 pots rears are the same as upgrading the fronts!

Actually they aren't.

For my car, I need the calipers and the pads only, I use the same rotors for the 4 pot. A bolt on affair.

The 2 pot on the other hand uses different everything so everything has to be replaced pretty much. They aren't bolt on, since my rear rotors are solid.

All subbies require the 2pot adapter brackets that various vendors sell for about $200 to get the 2 pot caliper on.

You will also need vented 11.3" brake rotors (06 wrx, 05+ LGT)

They're all the same design. The only difference is that the JDM IHI 4pot has "SUBARU" casted onto the caliper vs. a decal for the WRX, and different colors (black, grey, red).

22b had different brakes depending on who ordered them, majority used the same calipers as the JDM models, some used brembos.
