X5 looks great Jake! Glad you started a build thread, we need more of these on the E70 forum.
iND sells the painted front and rear reflectors, that's where I purchased mine from. The rears are super easy to swap on the M Sport - you can reach up from the underside and release the clips on the OEM red reflectors.
