If you own a Z3 or have ever driven one you have probably noticed the absolutely horrid position of the rear view mirror when attempting to look through any right hand turn. Be it in the mountain ripping it up and down the passes or simply just trying to turn right out of the grocery store parking lot, the mirror makes you momentarily do you best bobble head impression to insure nothing is in your path.
The stem utilizes the original tension spring mount reusing your existing hardware that can be seen in the V1 photos at the bottom of the page. The stems are 5-axis CNC machined out of 6061 aluminum and have a bead blasted and matte black anodized finish applied.
Fitment notes:
- The ball is still tight even after slimming it down a bit from the V1’s, but better tight than too loose. It is highly suggested to disassemble all mirrors to ensure the aging plastic casing does not break.
- There was an error during the redesign that is easily remedied – The OEM mount has 3 bosses for the screws that attach it to the stem, the respective counterbores in the V2 stems are too small, I sanded the bosses off my mount with no fitment issues.
- Dose NOT FIT Mirror PN: 51161932854
- For facelift non-M applications that have the alarm antenna/circuit board embedded the 8 lead wiring is UNLIKELY to fit through the stem
- Due to aging plastics, it is HIGHLY recommended to disassemble all mirrors to install the DBG stem to avoid breaking the casing/glass of the mirrors during reassembly.
