Is there a big difference?

I wouldn't take a newer Z51 suspension and replace it with Z06 stuff. I think the difference would not be worth the money spent.
IF you have older suspension, then I think it would be money well spent to match the springs/sways. This is what I did and I really appreciate the improved handling.
Of course I went from base suspension on a newer car, so the difference was more dramatic.
I matched these up to the Bilstein Sports and the combo is very streetable. Firm ride with great handling and no side stepping of the wheels (still on Mich PS run craps) yet I don't get beat up on everyday roads.

FE4 Suspension
The Z06 features a suspension system all its own designated FE4. It's not available on other Corvette models but is standard equipment on the Z06. It features a larger front stabilizer bar, a stiffer rear leaf spring, revised camber settings and unique shock calibrations, all engineered with a bias toward maximum control during high-speed operation. The suspension component specifications are:
Front stabilizer bar diameter (hollow): 30mm with 4.5mm-thick walls.
Rear transverse composite spring leaf: 125 N/mm versus 113 N/mm of the Z51.
Camber, front and rear: Z06: -0.75° (coupe/convertible: -0.25°).
The Z06's negative camber helps to keep the tire flatter in relation to the road, and raises the tire contact patch for greater grip while cornering. When coupled with other special Z06 components, the combination provides unparalleled, all-out racetrack performance, which is what the Z06 is all about. During development testing, Corvette engineers were able to generate racetrack speeds that improved Z06 performance by an average of 3 to 4 seconds per lap over last year's hardtop model on typical 2-mile closed-circuit road courses. This we were able to test for ourselves at the Mid-Ohio Sports Car Course in Lexington, where we had the chance to drive a standard coupe and a Z06, back to back.
If you add Z06 or better anti-roll bars and do not increase the rear spring you may not the way she handles in a curve.

So the main difference is in the rear spring the front springs are close.
