Default H6 Rear Rotor Options for WRX

I feel like I've never really gotten a full handle on the products available for this upgrade, and I imagine there are only a few... humor me.

What are the brand, model, part number, etc for H6-sized rotors that will fit on the rear of an USDM MY02 WRX with stock 1-pot calipers?


Make: Subaru / FHI
Model/Line: H6 (I guess that's what you'd put here)
Part#: Unknown
Size: 290x10
Design: Solid, non-slotted, non-drilled, uncoated hat (rusts)
Site(s): http://www.subaruwrxparts.com/wrx-braking.html
Notes: Of course... requires H6 rear brake upgrade brackets.

Make: Frozenrotors.com
Model/Line: H6 (I guess that's what you'd put here)
Part#: 96359
Size: 290x10
Design: Solid, cryogenic treated, slotted and non-slotted, uncoated hat (rusts)
Site(s): http://www.frozenrotors.com/
Notes: Of course... requires H6 rear brake upgrade brackets.

Make: DBA
Model/Line: Longlife
Part#: 657
Size: 290x10
Design: Solid, non-slotted and slotted, only the slotted version has a coated hat.
Site(s): http://www.dba.com.au (Manufacturer's site)
Notes: Of course... requires H6 rear brake upgrade brackets.

Make: DBA
Model/Line: 4000 Club-Spec Series
Part#: 4657
Size: 290x10
Design: Solid, non-slotted and slotted available, coated hat (resists corrosion)
Site(s): http://www.dba.com.au (Manufacturer's site)
Notes: Of course... requires H6 rear brake upgrade brackets.

Make: Stoptech
Model/Line: Direct OEM Replacement Rotors
Part#: 50-47017-101 (left, slotted) and 50-47017-102 (right, slotted)
Size: 290x10
Design: Solid, slotted or cross-drilled available, coated hat (resists corrosion).
Site(s): http://www.stoptech.com/ (Manufacturer's site)
Notes: Of course... requires H6 rear brake upgrade brackets. Search on website under '2002-2004' Subarus and you will see an Outback H6 selection. Cross-drilled is a different part number than slotted -- look it up if you want those.

Make: Carbotech
Model/Line: Direct OEM Replacement Rotors
Part#:
Size: 290x10
Design: Solid, non-slotted, slotted can be had from Boxer4Racing.com according to Carbotech sales.
Site(s): http://www.carbotecheng.com/ (Manufacturer's site)
Notes: Of course... requires H6 rear brake upgrade brackets.

Make: iON Performance
Model/Line: Direct OEM Replacement Rotors
Part#:
Size: 290x10
Design: Available slotted or cross-drilled. Cryo treatment available. Cadmium plating available (silver, gold or black).
Site(s): http://www.ionperformance.com/ (Manufacturer's site)
Notes: Of course... requires H6 rear brake upgrade brackets.

The 4653's WILL NOT FIT.
You must use a 290x10mm solid rotor.

Your options are the 657's or the 4657's

See: http://www.dba.com.au/dba_catalogue_...Out/Subaru.pdf

http://www.dba.com.au/dba_catalogue_...subaru_web.pdf

I believe Stoptech and carbotech have this size rotor available as well.

Some suggestions.

Describing either of the 657s as model 4000 is incorrect. You need to use just model or PN cause theyre the same.

IIRC DBA offers all their standard series in three configurations. Plain, slotted, or slotted/x-drilled. So in theory you would have:
657
657sl and sr(slotted left and right as theyre directional)
657x(non-directional)

You could call the 4657 a Club Spec rotor if you wanted to, its designed for more serious use. The 4657 is also slotted IIRC.

You might try PMing DBAStave for clarification of their current model lineup.

Are those hats coated a dark grey color and are your slots directional, one rotor for the left and right?

Are any of these options cheaper??

The pads fit in the caliper, not the bracket.

The bracket attaches to the knuckle and to your existing caliper to move it the proper distance radially from the larger rotor vs. the stock one.

Oh, and I meant to ask... this is probably well-known. Do H6 rears fit under stock WRX rims?

Where? I don't see it on the site.

FYI Carbotech gave me a 10% Nasioc member discount the last couple times I ordered parts from them directly.

No. The H6 rotor isn't vented so it is much narrower. Plus if you were to put a front rotor in the rear you would lose your parking brake.

Most of the info is great but a couple of points of order.

1. The pads do in fact fit into the caliper bracket, not the caliper. The caliper bracket dictates the pad shape more than the caliper itself does. The ears of the pads "snap" into the caliper bracket.

2. When discussing the rear brakes, the caliper bracket attaches to a heavy steel backing plate which is bolted to the rear knuckle. The caliper bracket doenst bolt directly to the knuckle. (The front caliper brackets, if so equipped, do directly bolt to the front knuckle.)
Rear hierarchy: caliper attaches to caliper bracket via slide pins, caliper bracket bolts to the rear backing plate, rear backing plate bolts to knuckle.
