Here you go:

• Firm Feel or Magnum Force Tubular upper control arms
• Ditch the KYB's and put in a set of Edelbrock Performer IAS shocks
• Go to the 1 3/8 front sway bar from Hotchkis and a 7/8 rear bar
• ABSOLUTELY install sub-frame connectors and if you can, get the XV motorsports chassis stiffening kit. It includes inner fender well braces and under hood shock tower brace.
• You've already got the FF stage 3 steering box with Fast ratio idler and pitman arms - good move.
• Minimum of .96 on the torsion bars. This will help you out A LOT.

The biggest thing I can see right off the bat are KYB's - ditch them, they're junk. If you really want to improve the ride and handling Ridetech makes a beautiful set of single adjustable. I just got them and am just waiting to do the install.

Remember, this an 18-foot, 4,000 lb car so if you're looking for Corvette handling it simply ain't gonna happen without going to a coil-over conversion and 3-link rear but that big $$$

Hope this helps.
