Yea they list their brembo conversion kit as having the rear backing plates so unless they have custom ones made they must be coming from sti. Would just grab that if the price wasn't horrendous.
On a side note, is there any way of getting the jdm cd's to work in english. Have us working in us program and jap in jap program but can't interchange to get jap cd's in english. Surely there's a way since the guys at subaru dealerships can get around it without too much trouble?
