Stock sway bar size list

[Shorty]

I get asked a lot what comes stock for sway bars on which Impreza. Here is a list I compiled:

FRONT

02-07 all models came stock with a 20mm bar in the front.

*Except STI's built from 8/21/03-3/31/04 which had a 19mm front bar.

REAR

02-07 Sedan/wagon

Exception:

Measured the rear sway on our 04 WRX Sedan. It is 17mm. Front is 20mm.
