I thought you were just running 10mm front spacers in the pictures I asked you about, and they looked about flush, but its been a while since i've seen them as the wonderful HP laptop I have them on died, either way, IMO it looked pretty damn good and not sunken.

Either way I dont know how much I believe the rears being sunken with a 15mm spacer, I can easily see where the 8.5+40 with no spacer is at that i've got bolted to my car at the moment, *shrug*, at any rate when it comes down to time for me to buy wheels i'll be going with a 9-9.5" rear, and 8" front, with all the offset I can get without the wheel actually touching the coilover
