2005 Corvette Part Two
The C6 was more evolutionary than revolutionary. The suspension was mostly the same, with some tweaking that resulted in better on-center steering feel. Chassis specs were similar, with C5 advances like the transverse leaf springs, balsa wood floor construction and hydroformed side rails also part of the C6. A similar setup was previewed in the 2004 Cadillac XLR. The C6 was essentially the same highly regarded suspension as found on the C5.
The famous Z51 suspension was packaged differently starting with the 2005 C6. In 2004 it was known as the "Performance Handling Package" (RPO Z51; $395.00) but in 2005 was promoted to "Performance Package" (RPO Z51; $1,495.00).
Along with different springs, shocks and anti-sway bars, it included larger cross drilled brake rotors (right), power steering and transmission fluid coolers, special gear ratios and Goodyear Eagle F1 SC Extended Mobility Asymmetric Tread tires. This would be the option to get if race track duty was your intention; think of it as the Z06 for 2005. The F55 Magnetic Selective Ride Control was not available with the Z51.
