I was just reading Tien's site, based upon an url furnished as part of the Maxximumtuning GD. The coil-over and EDFC looks like the way to go. If you compute what a good adjustable set of struts (if they made them yet for 5th gens) cost $450, and springs $200....you might as well tack on a couple hundred more and go full blown Coil-over and EDFC.

I would be interested to see how this works on the Max since its listed as an available part.
