Installed e63 M6 seats in my 4.6is today.
Direct plug n play 20-30 min swap just as the e46 m3 seats are. Note: both the e46 and m6 seat belt anchors attach to B the pillar -vs- the e53 which attaches to the seat frame. You could potentially swap top seat rail, but the e53 seat belt anchor fits perfectly to the rear bolt hole where the seat and rail fasten to the chassis. Also note: unplug the battery to avoid airbag warning light. Never liked the e46 m3 seats when I had one(e92 m3 seats are nicer in every way) and these m6 seats and also have adjustable lumber and side bolsters and so far they fit my frame(6’2 205 pounds) perfectly!
If anyone in SoCal wants a pair of original 02 sport seats let me know. $250 for the pair(driver side heat element imperative.)
