Much depends on how much camber you're running. I just completed this exercise yesterday for a new set of wheels I'm getting made. I'm running -1.6 camber in the front and rear of a lowered car. To achieve a near flush stance, I'm going with 9.5x20x36 and 12x21x51. With a 12.5 rear, the equivalent would be ET64. The 5mm or so difference between the numbers you were given and mine is that mine account for camber.

Not aftermarket wheels, but had a local wheel painter re-paint the wheels on my 992 GTS. He mixed the color for me and it took a few iterations but it is meant to be sort of a dark bronze (there is no specific paint color/code). Almost like the Aventurine Green color, depending on the time of day this wheel color always seems to look different.
Was sick of the stock painted silver color getting dirty after just a few minutes of driving... One of these days I plan to get some custom wheels (maybe like pad bender's) but these will do until then.
