Picked up a hirsch style spoiler for my 07 9-3 sport combi for a self xmas present and it really didn't come with mounting instructions. Looked around but couldn't find anything online or even a thread about anyone having one. Anyone have any experience installing one, etc...didnt know if you just pull back the headliner, undo some screws and take off the old spoiler. Also picked up an aero lip too......I have no clue why every pic i upload always displays flipped. They look good on my computer.
