Thanks everyone, as Sudesh has so kindly posted the diagram, I have the stock 4 arm standard wheel now. So far, I was looking to go to the last diagram he has listed, believe its the latest 4.8 wheel. But the board seems to suggest going for the M wheel so I have some research to do. Is the airbag under my stock wheel different from that of the sport wheel? I know the casing is different, but can the airbag be transferred? I know it's probably a stupid question, but have to ask. TIA
