I couldnt find a direct comparison thread. Is there a significant handling difference from the z51 to z06 shocks? Any info would be great.
Sure there's a difference. The Z51 shocks are for a base cars sway bars, weight and F to R balance and the Z06 shocks are for the Z06 sway bars, weight and F to R balance.
As we all know ; the factory set ups are a compromise. Trying other componets may suit your needs for your driving style.
I'm guessing the z51 shocks are close to or the same as the Grand Sports.
I put Z06 shocks on the rear only, of my GS . These worked better for me than the GS valving. They cut down the amount of oscillations over bumps.
My experience was different, I found the Z51 shocks on our factory Z51 to be too harsh for normal driving on the bombed-out roads of Illinois. I actually replaced them with base model shocks and felt that real-world cornering suffered only a little, but the ride got much better. Other folks have been happy with Koni FSD's or or Bilstein HD's.
I would consider Z06 shocks only if I lived where the roads were smooth, and was doing track weekends with the car.
But, YMMV.
Sways and springs are designed to work together as a package, so I'm not sure how that combo would work on a base car.
The Z06 has wider rear tires, so the Z06 pckage is designed to work with them. Putting a full Z06 suspension on a base car is reported to produce oversteer.
