But as I said above, I don't recommend simply putting STI springs on the stock Forester struts.

The rear bars on the 04/05/06/07 are all different rates between model years, but all with the same fitment. This means that they made damper and spring rate changes through the different model years. The 04STI uses I believe a 21mm and the 05 used a 19mm. The 06 went back to a 20mm and the 07 went back down to a 19mm again.

This is why when we were testing out the Swift Stabilizers for the STI we were trying to see how much of a difference the bars made for each model year. Because we did not want it to be at a point where the bars created any ill handling affects. So it took awhile to find the necessary model years to test the reactions on each model. Another reason why Swift did not originally want to design the bars for the STI because of the rate changes for each year. They warned us before we began any testing on the bars.
