I'm looking at upgrading my suspension to Koni Yellow + Eibach Pro kits, I'm currently on stock ZHP wheels with tire sizes: F:235/40/18 and R: 265/35/18.
Additionally, I have Z4m FCABS which added a bit of caster to the front wheels, Will i need to roll my fenders or RUB?

I think you will be fine. Drops like an 1" ish. Stock wheels have high offsets as well so it doesn't stick out of the fender far enough to become a problem.
