I got some MB copies through Rob last week for the Aero.... they are the AMG style 810. Front is 18x8.5 with the Kumho Ecsta 235/40's and rears are 19x9.5 with 285/35's... here are pics of the rears..(the lug bolts were too long and need to be trimmed)...






The rear wheels have a small problem (for me)..... when I pulled the OEM wheels off the new wheel/tire combo would not go on the hub... the tire interfered with the body at the bottom front of the wheel well... .... I just put a jack under the arm at the spring and jacked the hub up some so the wheel could be mounted, tightened it and then lower the jacks... they are fine in normal operation, just not with the suspension hanging free in the air.....
The plus side is the -32 offset and wheel size/style puts the wheels out at the fend edge with NO spacer...

The fronts also allowed me to remove the spacers and clear the C32 brakes easily.... I do have to grind that one bolt down to make sure I have no possibility of touching the inside of the tires...

More pics on the car when I get it back from the shop....(another story)
