I bought the Bilsteins and Eibach's from Heasman's in Sydney, the Bilstein distributor in Australia.
I got both front / rear B8's and front / rear Eibach pro-kits for $1900. I think the B8's were just above $1100 on their own. If you're interested just speak to Tony at Heasman's and just mention that you were referred to him by another MPS3 owner whose girlfriend came and picked them up a couple of months ago. He'll look after you well ... and if you do choose to purchase, you get some nice Bilstein vinyls, a couple of official Bilstein hats and a nice lanyard
