I hate to see an unanswered question especially about shocks.
I have Edelbrock IAS on my 92 GMC Jimmy. I know it's not the Vette, but I can still tell you how they feel.
I've had them for 2.5 yrs. and the ride is great! The truck stays level on hard corners, it firms up over bumps and rides smoothly with normal driving. My truck handles extremely well and I feel confident with these shocks. If I didn't, I wouldn't have them on my everyday car. IAS shocks self adjust, from performance to touring as your driving style changes.
Three years ago, the Guldstrand GS-80 Corvette, was used to develop the IAS as a performance shock. After months of development and testing, they proved themselves to be excellent shocks for either performance or touring. The shocks were very impressive and held up to quite a bit of punishment.
The shock was a prototype when it was used on the GS-80, but today it uses the same valving as it did then. The IAS are fabulous shocks for everyday casual driving, but when you need to flex your cornering muscles, the IAS won't disappoint.
