Default New car, couple of questions

CAGS -- How do I disable it -- trying to shift into 2nd and it wouldn't go, had me all freaked out until I got back to the house

Was the Active Handling system an option for 98?... Car has the Z51 handling package (according to the Sales guy), and also has the Active Handling system as well (included with the Z51 package??)

Column Lock Bypass -- Somthing I should definatly do? Some have told me yes, some have said no?


Oh man I love this car

Default RE: New car, couple of questions

You can buy a CAGS defeat at almost any Corvette supply house like Zip, Ecklers, MAD, etc. I never did this, since I normally shift as soon as the shift light goes out. The CAGS is active only when you see that shift light.

Definitely do the CLB if it has not been done AND the dealership had not previously removed the mechanism (They have been doing this for a while). After about 1500 actuations, the CL will fail, potentially leaving you stranded.

Here's some info regarding changes throughout the years:

2001 had the greatest number of changes of all the 5th generation models.

1997
* Completely new, redesigned Corvette. Base (FE1) and Z51 (FE3) suspension packages.
* All Z51 cars include: Power Steering Cooler
* 97-00 C5 LS1's produce 345 HP @ 5600 RPM and 350 Ft Lbs of torque @ 4400 RPM.

1998
* Convertible becomes available
* Active Handling becomes available late in year
* The two slots of a 1998 (and possibly late 1997s) curve toward the rear at the bottom. (versus straight down)

1999
* 26# injectors substituted for 28#
* Fuel pump revised to reduce noise
* FRC "Fixed Roof Coupe" aka the hardtop, becomes available. All FRC's are MN6 (6-speed) cars with the Z51 suspension package, and are about 60lbs lighter than coupes.
* HUD introduced
* Only one line in driver's side fuel rail cover (no fuel return line?)
* Power telescoping wheel becomes an option
* Steering hardware changed to combat wandering
* Door sill trim plates added

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)

* Alternator 'clutch' pulley added on A4 cars
* New soundproofing + foam in all cars

* 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

* 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
