I’ve been quietly reading along for a while, but I figured it was time to introduce myself. My name is Mike, based in the south-region of the Netherlands (Limburg), and since January 2026 I’ve owned a 2003 BMW Z4 (E85) with the 3.0 engine and a manual gearbox.
I’ve already carried out a number of OEM+ upgrades on the Z4, including a fixed wind deflector, an upgraded head unit with BluMusic, US-spec rear lights, and the cruise control retrofit. I also had the wheels refurbished; they are the original BMW Style 108 alloys. A suspension drop with an ST coilover kit will also be carried out within the next few weeks.
My next project is already planned: installing white indicators in my headlights. I’ve bought two sets. I might need some tips for cutting open the headlights, as I noticed many of the photos on this forum—where useful tips were shared—are no longer available.
