I strongly recommend getting actual gauge faces from Venoxy.com as you peel and remove your stock face panel for a proper OE quality one.

They are not stickers that you slap on top of your OE faces (like Eurocustoms lol). They are proper OEM material and thickness, with blotting ink on the backside so it lights up 100% stock. The font consistency, spacing, typeface is 100% OEM. I am incredibly OCD about details such as this, especially when modifying the M. I was legitimately impressed and did not expect this level of quality especially at less than what crappy sticker overlays cost.

I bought a set of grey ones for my 328i and red for the M3 (haven't installed these yet). Absolutely perfect quality and he can even make the "///M" backlit.
