07+ Brake upgrade on a 00-06 NBS, is it worth it?

What is the difference between the Police Pursuit calipers and the standard calipers?
Is it just seals?

Basically, the non-metallic stuff in the calipers is made of a more heat-resistant material, including the seals.

Sorry I must be late to the party but does REAR calipers from 900/K2 fit Tahoe 800 bolt-on?
