Installation Notes

No installation hardware is required. This is considered an accessible, easy DIY. The original caps need to be pulled. Trim tools may be useful.

build journal: product series

Recreating the discontinued original.

BMW M has began discontinuing the M Performance product line for the E9X M.

They started with one of it's most sought after product: the carbon fiber mirror caps.

They were their most popular product in the lineup for a reason: they improved the overall aesthetics and they were 10/10 quality.

In this Product Series, I document the initial development of the 1:1 Carbon Mirror Replacement Caps with Karbonius back in 2020. I discuss the prototype, my first impressions and its eventual discontinuation in 2023.

In 2025, I have set out to create a new option for sourcing 1:1 replica of the original BMW Performance caps.

Enjoy,
- Matt
