Can you confirm that the new '06 red 4-post DO NOT have the "Subaru" cast into the caliper like the old grey ones?
I test drove an '06 WRX Limited Wagon and took a close look at the front and rear brakes. Both front and rear calipers have a white "Subaru" sticker. The older style had "Subaru" cast into the caliper and then machined smooth so the words are shiny.
Also, it looks like the new grey calipers are the same way as the new red ones. Can you verify this?
I guess Subaru figured out it was cheaper to slap sticker on there instead of milling the calipers!
