01 and newer C5s had dynamic rear brake proportioning.
The dynamic rear proportioning (DRP) is a control system that replaces the hydraulic proportioning function of the mechanical proportioning valve in the base brake system. The DRP control system is part of the operation software in the EBCM. The DRP uses active control with existing ABS in order to regulate the vehicle's rear brake pressure.
No need for a spring. Basically, it means if the rear tires have traction the system will add more rear brake bias. If you are running sticky tires on the track it could add a lot more rear pressure and cause the rear brakes to wear faster.
