I just bought a 92 300TE and she's totally stock so here I go - I have lowered 2 190's & a Volvo wagon with Eibachs, H&Rs, Bilsteins, etc so I know my way around a suspension but I'm not knowledgable on the wagon set-up and this self leveling system, what do I have to do differently to install after market springs & Struts? Is it as simple as just removing the old ones or do I have to block off hydraulic fluid and cap the system somehow? Thanks in advance for the help!

you'll have to adjust the arm for the SLS sensor so it can know the new lower setpoint. I would disconnect the arm, lower the car, start the car, and bolt the bracket back together. The SLS compensates for extra weight in the rear of the car from a set point.
