Does anyone have access to a FSM or something so they can help me?

I'm looking for:

Front Caliper Piston Diameter/Radius: 42.8mm/21.4mm
Front Rotor Effective Diamter/Radius: 253mm/126.5
Rear Caliper Piston Diameter/Radius: 38.1mm/19.05mm
Rear Rotor Effective Diameter/Radius: 254mm/127mm

Thanks.

Per the FSM

Front Caliper Piston Diameter/Radius: 42.8mm x 2
Front Rotor Effective Diamter/Radius: 253 mm (OD 302mm)

Hardy,

I know this thread is ancient, but can you or Todd provide the rear rotor OD?

Also, by looking at those numbers and what I have in my spreadsheet
http://www.main.experiencetherave.co.../brakemath.xls

The front rotors are larger then what the WRX even currently received. Has anyone verified the FSM data? It just seems a little suspect to me.

Thanks

It's all accurate as far as I can tell.

I posted what the rear rotor diameter is on nabisco.

I wouldn't be suspicious. The SVX had the largest diameter front rotors of any Subaru up until the brembos. You should see the pads, not that it really depicts rotor size, but they're huge. The rear were the largest up until the 2 pots/BE/BH I forget which came first. The front thickness is huge too, 28mm, BL/BP size. And apparently the JDM spec SVX's had 290x18mm rear rotors, VENTED! Hell of a braking system.
