Z51 vs. Base Suspension
One of the biggest takeaways is how different ride quality is between the base suspension and the Z51's performance suspension. Base and Z51 Corvettes may as well be two completely different cars.
For $2,800, the Z51 package adds invaluable performance features to move the 'Vette as fast as possible around a racetrack, including a sport suspension, unique chassis tuning, larger wheels with higher-performance tires, and much, much more. A Magnetic Ride Control suspension with adjustable firmness is a separate $1,795 option available only on 'Vettes with the Z51 package.
The Z51 is a more refined performance package than the former Corvette Grand Sport, which was a fast but raw experience. Similar levels of handling are achieved without the Grand Sport's disturbing front tire chatter, which reverberated through the steering wheel when turning into a parking space.
The Z51 package's awesome performance for the money is offset by its ride quality. Z51s ride with the subtlety of a battleship speeding through a no-wake zone. I struggled to differentiate ride quality of the optional Magnetic Ride Control suspension's Tour, Sport and Track settings over choppy roads. Enthusiasts may not find the ride quality overly offensive coming from a car with lowering springs or stiffer shocks.
Dropping the Z51 package transforms the Corvette into a car completely capable of driving cross-country in comfort, with a soft ride that's still taut enough to be considered sporty. Many Corvette owners enjoy driving and do a lot of it — whether it's from car show to car show or cross-country on vacation. A base-suspension 2014 Corvette is the car those buyers want. Getting from home to the racetrack may be as far as you want to drive the Z51.
