Brett,
your brackets are very similar, but being for the front, mine look a bit deeper. Overall demensions are 185mmx52mmx37mm, I checked with a local supplier for material 2040-T315 and found prices of £60 for one peice so it isnt cheap. Together with machining and stainless spacers between radial mount and caliper, its loadsamoney.
Cost aside, the brakes are the most important part on the car, so I havent compromised here. But to reduce the impact on the wallet of the total front and rear brake system cost, I took my Impreza off the road, and am currently saving £100 month in fuel -thats dedication to the GT40 for you
