The caliper/rotor combinations chosen work very well with the OE master cylinder. Bias is shifted slightly rearward as OE is too biased too heavily on the front. Most owners lower their cars, often using stiffer springs and better dampers. This decreases weight transfer to the front under braking, allowing the rear brakes to contribute more. Pedal travel is reduced as compared to stock, mostly due to stiffer components and stainless steel brake lines.

True, but there are also other caliper features that can decrease pad knockback than just springs. Knockback is not an issue at all with AP Racing brake kits on the 370Z. Also, there are several AP Racing street calipers that use anti-knockback springs as needed. The setup in question here is not one of them.

Possibly, in certain cases. There is no blanket answer. The stiffest monoblocks ever made used very expensive and very eco-unfriendly materials that have been banned in most racing series. Kits which cost
less than $12k per axle would
not have those type of monoblocks. At "normal" BBK prices, many monoblock caliper designs have a very difficult time competing against the better designed and manufactured 2-piece calipers.

The kits are available with slotted-only or cross-drilled AND slotted discs. For heavy track use, slotted-only is recommended. Cast-in holes are a Internet myth.

I think weiboi718 should answer that one! But his review highlights some of the benefits he has already enjoyed.
