Which is why it needs an engine boost to keep up with the other mods... to stay balanced.
The Z06 is already a finely balanced machine. Now you are upsetting that balance with bigger brakes and stiffer suspension without any power increase to use it.
I never saw the point of it in the 15 versions of Mustangs with the same stock GT engine either. 16" brakes, 8 piston calipers, 500 way adjustable coil overs, this and that... and the same virgin 260-300 HP engine. It's mostly just for looks and to take money from non car people who don't know any better. Big profit margins on brakes and coil overs, not so much on engine parts; $5000 brake kit costs $1000 to make, $5000 supercharger costs $4000 to make, etc.
Good suspension and brakes can be fun too, but only if an upgraded engine is a given. That's the first thing anyone cares about when you build a car like this.
