It didn't come with any shims. Keep in mind, I did not get this bulb from CSC but it appears to be the same manufacturer and style. I actually just came in from modifying it. I cut off the light deflectors on each side and orientated it so the LEDs face up and down instead of side to side. Obviously I am destroying the bulb but for experiment sake I don't care. I also have another brand new bulb as it was pack of 2.
This is the bulb.
Original install is in my blog here:
