Hi....welcome to the Forum

I suppose it depends on how good condition the roads are where you are as I personally wouldn't run on 40mm drop with low profiles but 30mm all round would give the car the right stance and still return sensible (?) driveability.

Let's see a pic of it once its lowered....be good to see what it looks like
