Burning Brakes
2001 and newer have a higher power version of the LS1, 350/375 instead of 345/350. I can't remember any of the other differences but the engine upgrade was fairly substantial, the newer motors have much more low end grunt.

Here was info posted on the forum a while back. There may be other differences too, but these are a good start.
Difference in Corvettes by year:
2000
• Millennium Yellow available
• "Thin Spoke" versus "wagon wheel" design wheels become standard.
• Pup cats added to all models for LEV emissions requirements (5hp loss relative to 97-99)
• Steel swaybar endlinks instead of plastic on Z51 equipped cars
• Z51 swaybar diameters grow (25.4/21.7 to 28.6/21.7 to 28.6/23.6 (note: new rear same as Z06)
• No keyhole on passenger side doorhandle
• Passenger airbag 'off' switch added to console (light by TC/AH button)
2001
• Return to 28# injectors for all models.
• Second Generation Active Handling
• Nassau Blue discontinued
• Alternator 'clutch' pulley added on A4 cars
• New soundproofing + foam in all cars
• Smaller keyfob
• Electrochromic dimming rearview and driver's mirrors
• Lighter AGM battery
• Thickness + Material in Convertible change
• Chrome exhaust tips for coupe + Convertible
• 85MM MAF with integral temp sensor (versus 74mm with separate plug for IAT)
• LS1 cam profile changed to: .500/0.500, 198/208 on 115.5LSA (From: 0.472/0.479, 202/210 on 117)
• All Corvettes now have the LS6 intake manifold
• All Corvettes now have the LS6 engine block (windage passages in block), which includes a beefier oil pump.
• LS1 changes result in new output of 350 HP @ 5200 RPM and 375 Ft Lbs of torque @ 4400 RPM (MN6)
• Hardtop/FRC discontinued
• Stronger synchros in all transmissions
• Exhaust manifolds revised (5hp regained) - thin wall cast replacing SS manifolds
• Metal valvestem caps (late year)
• Torque Tube changed from metal-matrix composite to aluminum alloy 6061, increased in diameter from 55 to 63 mm.
• Driveshaft couplings have also been upgraded on manual-equipped models for additional strength and durability
• Introduction of the Z06, which has as differences:
• Hardtop body style
• Rear brake ducting
• Screened inlets on front fascia, without foglights
• F1 Supercar tires 265-17 front, 295-18 rear, on 17x9.5 and 18x10.5 (one inch wider, respectively
• New LS6 top-end with new style head design (10.5:1 compression, 64cc chamber), LS6 cam (0.525/0.525, 204/211 on 116) - 385hp
• M12 transmission with shorter gearing (1-2-3 analagous to MN6 with 3.90 rear diff
• Titanium exhaust system
• Lightweight windshield
• New, stronger clutch with redesigned master + slave cylinder
• Stronger rear differential (shotpeened ring gear)
• Red brake calipers (otherwise identical)
• Transmission overtemp warning light on DIC
• 6500 redline gauges with special checkering + Z06 font
• Redesigned PCV system to help combat oil burning
• Red LS6 Fuel Rail Covers (FRC's)
• FE4 Z06 suspension - uprated springs, bars (30mm/23.6mm), shocks (note front spring and rear bar same as Z51)
2002
• Z06 Changes:
• Z06 LS6 cam changed to: 0.551/0.547, 204/218 on 117.5
• Less restrictive intake airbox lid
• Descreened MAF
• Removal of pup-cats (total with changes = 405hp)
• Z06 shocks revised with less rebound for better launching
• Z06 brake pads revised for better stopping (generate more dust)
• Lighter, sodium filled valves w/ stronger valve springs
• Higher tension rings installed to prevent oil burning problems
• Slight piston redesign *
• Clutch strength upgraded.
• HUD available on Z06 (not avail '01 model year)
• Wheel supplier changed to Speedline, moved from forged to cast. Weight nearly identical
• Electron Blue color offered
• Steel endlinks changed to aluminum
