Not a ZHP. But my wife's E39 '03 530i.
Replaced front and rear Struts & Shocks with necessary associated kit (FCP Euro) with Bilsteins B4 (ECS Tuning). Alignment.
Replaced spark plugs with NGK and Mahle Fuel Filter due to jerking when shifting gears like fuel starvation. Solved the jerking.
Replaced Transmission and Differential fluids with Red Line.
