I have just replaced the original Tein coilovers on my 2007 3.0 with latest version, as one of the shocks snapped. It was not cheap at all, as I had to replace various other suspension bits as well including the rear axle beam bushes, which is a big job. But Tein seems to be the way to go. I was recommended to have the rear suspension higher than the front, which I think means I am maxed out on ride height. I don;t like the rake so much from a visual perspective, but speed bumps are fine and I can still get in car parks with max 2m height restrictions.
