Yeah, I TOO was thinking on getting rid of the car. But it just works too good for me in Stock. Plus lately I've been playing around more and more with setups. And that's helped out too. Wish I had the MS (just to have the one piece lower bulkheads). But my IV is just fine the way it is.
Yes, the EvoIV and EvoIV MS both have the same LW suspension. Only difference with suspension "change" is the MS comes with 415 suspension mounts that are 1mm lower than the original EvoIV mounts. Basically changes roll centers. 415 mounts have the "1"X or 1C, etc. It has the "1" on it before the letter. The EvoIV mounts just have a letter on it... "C" or "A"... etc.
