Wow. What size wheels are those then? They don't look very big. What brackets did it take to get the 7er calipers on the front and the 5er on the rear?

Sorry, I know this isn't e30tech haha. I am just so interested as I want to do bigger brakes on mine and am not sure which way I want to go. I have not heard of this setup before.
