Z51 performance handling package
 

What was included in the Z51 Performance handling package on a 2003 Coupe? How did it differ from the standard FE1 suspension?

Stiffer springs, different shocks, bigger torsion bars and a power steering cooler. All but the power steering cooler are easily added in the after market with Z06 or better parts.

:iagree: The Z51 Performance Handling Package consists of the RPO FE3 Sport Suspension and the power steering cooler. We ordered the Z51 package in our car and it is my favorite of the C5 suspensions. Here are a few more links on the C5 suspensions that you might like to review:

What are the differences between the C5 Suspensions?

Whats the easiest way to determine which suspension is installed on your non Z06 C5 since the build sheet is somewhat difficult to view :)

Look on your RPO tag. It will be listed there, either FE3 (Z51) or FE1 (base)

The RPO tag is either on the underside of a rear compartment lid OR inside the glove box on the door. Depends on year of car where the RPO tag is located.
