Just dont do what I did and order ALL the M3 parts, deliver it to your mechanic and realise you are missing just 1 rubber mount for the rear sway bar.
ARGH!
Tried to order from BMW spare parts here in Sydney and they said that the part number had NEVER been ordered before and would take 3 weeks.
Such a shame to express a $20 part from the USA for $60 in shipping...
You learn i guess
