I'm leaning towards the Wagner FMIC since it doesn't require a bumper removal or cutting the trims to fit.
As for more aggressive tires, I have 19" on my black Z4 and it's good for Europe but the poor road conditions in Asia makes the 18" more practical. Might give the 19" tires a try on the next tire change.

FMIC will only get you to "stage 1+" you need the downpipes for stage 2 off the shelf tune
Use the 18" tire but get a more aggressive compound. You are already traction limited in 1st with the PSS and your Cobb stg1
