I'm not saying anyone should or shouldn't do this mod. Just pointing out that the standard 135i ratio isn't exactly slow.

Uhm 14.9:1 @ 2.6 turns is massively different from 16:1 and needing 3 complete turns. The M3 12.5:1 rack takes that 3 turns down to 2.5 or so which would put it more in-line with feeling the same as your Porsche.
There are also track width and wheelbase considerations that need to be factored in to just how well the car turns with x or y steering ratio.
If you think 16:1 isn't that bad on a bmw then you've never autocrossed lol. You need 2x as much hand movement as an FRS/BRZ, Miata, or even older BMWs that got quicker racks like the Z4.
