I've always wonder how much truth/validity there is to the saggy butt syndrome that everyone complains about. Is it really saggy butt because take-off setups drop the car incorrectly, or is it because the fenders just look that way from the get go.
Today's project involved taking my '05 FXT from stock struts with Forester specific pinks to '04 take off's w/ RCE Blacks.
Notes of interest. As noted in Porter's thread, the front struts in terms of knuckle to spring perch relationship are indeed the same. The rear Forester struts have ~0.5" more space between the knuckle mount and bottom of the spring perch. So with that said, the same given spring on both struts would result in 0.5" taller rider height in the rear. This does promote the theory that saggy butt does occur with STi/WRX take-off's.
I took some measurements using suspension mounting locations as "control points" versus the fender. Installed the '04 STi struts w/ the RCE blacks, jounced the suspension and remeasured. Hmmmm...
So the front dropped nearly another 2.25" whereas the rear only dropped about 1.5" End result is the car actually sits higher relative to the front than it did previously. Go figure.
Argue away. Very important note is that these are RCE Blacks so the spring rate is pretty high on them. I'm wonder if the front/rear weight split on an STi may result in the rear sitting down a hair more. Uncoming plans involve an R180 out back, so we'll see how that affects things.
