Disc size

Would anyone have a definite answer as to what size are the rear brake discs on a 02 wrx with 2 pot calipers as standard.
I'm not sure if there a 290mm disc with 170mm or 190mm hub size.

Cheers
James

james it says on godspeed brakes site that the 01-09 wrx using a 290mm rear disc has a 170mm handbrake shoe hope this helps
