Did you consider or research replacing the struts with KYB or Bilstein's?
Please do! If it’s easy I may do it.
The reason I want to install the RSSs is to bring the rear camber back closer to OEM specs as much as possible since rear camber is not adjustable otherwise; and the rear shock extensions to bring the shock travel closer to original. Here's the rear alignment specs from service manual.Please do! If it’s easy I may do it.
However, Eibach has produced more suspension components than probably all the other companies combined. The lead engineer races Subaru’s. I have no reason to doubt what they recommend. I will post up if something happens but nothing looks stressed at all with this mild lift.
Best part for me is beyond the increase stiffness and handling. I no longer bump my head on a open rear lift gate and it’s easier for me to put my daughter in her car seat. I stand straight up vs an awkward semi squat.
Good work, looks great!I finally gave in and did the installation despite its being a little cold. Just plugged in an electric heater, cranked it up and went at it while drinking Covid-19 antidote.
I ended up NOT installing the rear subframe spacers, the brake line bracket extensions, nor the rear shock extensions. If you guys look at the photo comparing the Eibach spring assembled vs the OEM spring assembled, you will understand why (both are the same length). The way Eibach achieved the lift is by making their springs stiffer and hence can hold the weight of the car while not sagging like the OEM. Unlike the LPAventure, Anderson Design, etc. lifts using strut spacers, since the Eibach assembled struts have same dimensions as stock in fully extended (relaxed) state, there's really no need to do anything to correct alignment. Shock's travel shouldn't be a concern either because the max extended length is the same as stock.
Primitive's lift kit using King springs works similarly to Eibach for the front, but they use longer springs + rear shock extensions for the rear so the final assembled rear strut length is longer. So they require the use of subframe spacers. Even though Eibach rear springs are longer than OEM, once assembled they're still same length as OEM.
Once I get a wheel alignment, I will confirm my conclusion above by checking the rear camber numbers. But I'm pretty sure I wasted money on the subframe spacers kit and the shock extensions.
Sorry for being long winded, here are the photos during & after installation.

Like I said above, the king springs on the rear are longer and they also use the shock extensions to make the springs work at that longer length. The Eibach rear springs are longer too but compressed by the top hat after assembly into the strut (without using shock extensions) so same exact length as stock because Eibach designed them to work at stock length.That is very interesting. Still surprised there is no extra stress on other joints that require the sub frame spacers. I mean it is still lifted about 1.5 inches, right?
Curious why Primitive recommends and includes it with their kit. Apparently the King springs are 25% stiffer than OEM, which I thought was even stiffer than the Eibach's? Does that mean that the King springs are not only stiffer they are actually taller as well?
I think this is not advised. I’m in the reverse situation. I have the primitive 1.25” lift. Love the springs and ride. I want one more inch. The usual suspects LP, ADF, and primitive have told me not to put 0.75-1.00” strut spacers on top of the spring lift. Many reasons. Subaru’s are not trucks or Jeeps.So, what happens if you install lifting springs with a spacer lift? Double the lift?
Since installing the lp lift kit I've been thinking about upgrading my springs for a little more stiffness, but am not necessarily looking for more lift...
Wow yours looks great! Hoping I can get a couple more details and even some additional photos of your Subaru. I’m looking to do the same to mine. Did you put the sub frame spacers on as well? About how high did the front and rear lift after the install?
