Are there any differences between the Z06 between year to year? I'm looking into picking up a Z and was wondering what years were problematic, what I need to check, what to stay away from, etc etc. Just pretend you were to buy another Z, what problems have you had so I can check when looking at cars.

 

There were numerous differences from 2001 to 2002; then relatively few between the years that followed in terms of how they are built and optioned.

We have an excellent sticky'd thread which outlines everything you'd ever want to know about these differences, and about Z06's in general. I spent several weeks digesting it all before I made my purchase decision, and have since forgotten a lot of it. So, have a look here:

Hope that helps!

 

Thanks for the helpful link

So my question is, between the 01 and 02+, is it a noticeable difference (other than the hp/tq gain) from the two. Better handling or lighter and so forth?

Also, common problems that go wrong with these cars would be good to know about for me to check out when I get out the cars.

 

More Power
Last year's introduction of the Z06 Corvette, based on the former hardtop model and the legendary 1960s Z06 option package, is aimed at true performance enthusiasts at the upper end of the high-performance market. And now, an extra boost of 20 hp, to 405, makes Z06 the quickest production Corvette ever.

This upgrade to the LS6 engine's output is the result of new hollow stem valves, a higher-lift camshaft, a low restriction mass air flow (MAF) sensor and a new low restriction air cleaner design. Eliminating the PUP converter from the exhaust system enables better flow of spent gasses and reduces vehicle weight, without compromising Corvette's NLEV (National Low Emission Vehicle) status.

Suspension Upgrades
The Z06-specific FE4 High-Performance suspension system features a larger front stabilizer bar, a stiffer rear leaf spring and specific camber settings - all calibrated for maximum control during high-speed operation. The 2002 model year Z06 also has new rear shock valving for a more controlled ride.

Although retaining the same design and color finish, the unique aluminum Z06 wheels are now produced using a cast rather than a forged process. The magnesium wheel option for Coupes and Convertibles is no longer available.

Maximum Agility
The foundation of Corvette's agile handling is hydroformed frame rails. Its four-wheel independent front suspension features cast aluminum upper and lower A-arms. The Z06 and models equipped with the available Z51 package now have aluminum front stabilizer bar links for lighter weight. A transverse leaf spring system is used for the independent rear suspension.

All Corvettes have the second-generation Active Handling system as standard equipment. The system features dynamic rear brake proportioning to prevent rear wheel lockup; rear brake stability control to assist the driver in maintaining control under light braking and high acceleration conditions; integral traction control calibrated to allow drivers to experience the vehicle's power and handling while maintaining control over excessive wheelspin. It also has an on/off switch and a "Competitive Mode" which allows the driver to disengage the traction control feature without giving up Active Handling's other benefits.

Additional Refinements
Now standard on Z06, the Corvette's Head-Up Display (HUD) projects vehicle speed and many other gauges digitally on the windshield ahead of the steering wheel, enabling drivers to keep their eyes on the road. HUD remains an option on Coupes and Convertibles.

For 2002, the transmission cooler case is constructed of lightweight cast aluminum, replacing the previous stainless steel design.

Corvette's exterior color palette adds Electron Blue, replacing Navy Blue Metallic previously offered on Coupes and Convertibles. Electron Blue also takes the place of Speedway White as one of five choices on the Z06.

That should get you started.
