Dean, you yourself have said many times that the STi strut clunk comes from single bushings on the strut; you are assuming that the Ohlins have the same problem. I haven't seen anyone complain about noise from them, although there is of course a limited sample of real-world use to draw from.
Also, the RCE/Ohlin combo meets all of the requirements Dan listed, except that it doesn't have EDFC compatibility, which didn't seem all that important, and the
possibility that it will be less capable in snow.
The three of you seem far more interested in shooting down my suggestion than in giving Dan options. But clearly, the Tein Flex is now the superior suspension solution for every Subaru owner on the planet, so why not just lock the thread now and submit Dan's order?
