If you search around the forums (search feature in the upper right hand of the page) you'll find a couple people who have also wanted to lift their Foci. From what I have read, lifting is far more expensive than lowering and nobody has done it yet besides rally drivers. If I'm not mistaken, the lifting coilovers will run you about $3k-$4K since they are built for rallying.
