I don't think these were the ones I saw. Anyways, members in these threads were saying they need to retro fit A8 airbag on the wheel. However, the wheel I might be able to get through a friend already has the original airbag on the wheel. Not sure if it's a direct bolt-on replacement without any coding or error message though.
As much as I want a flat bottomed steering wheel (and I really REALLY want one) I think there's something really "basic" looking about the wheel in your pic. Something about the centre just doesn't work for me, I understand that an AirBag needs to squeeze in there but there's too much design compromise IMHO.
Again, it really shits me that an S3 gets a flat bottomed wheel and not an S5, when the S5 is double the price! (In Australia)
