These wheel alignments are not factory standards. These are derived from tests, professional drivers and chassis engineers.
You should always consider driver, fuel, and cargo weights when your Corvette is aligned. Please note that these specs are symmetrical. For examples, when we recommend 1/8″ toe in, that indicates 1/16″ on each front wheel for a total of 1/8″ total toe in.
Daily Driver – These specs are designed to minimize tire wear and dynamic forces on front end parts. Driver effort is minimum, the car will steer very “light” and may wander or be “darty” on road with wear ruts. If you are uncomfortable with this feelings, toe the car in up to a maximum of 1/8″ total toe in.
Advanced Street – These specs are designed to give an even quicker steering response with minimum tire wear. If the car is “darty,” toe the car in. By toeing in, you may lose some turn-in qualities gained by the initial specs.
Autocross – These specs are a good baseline to start from. The driver must take into consideration the size, compound, and condition of the tires. The chassis is affected by the valve package in the shocks, spring rates, and sway bars. The Autocross course design and the condition of the surface will also have a bearing. These specs do not work and are not recommended for street use because of adverse tire wear. The car will act “nervous” when ever changing street surface.
Track – These specs are by far just a baseline. Those of you who race know alignment specs will change based upon weather, track, and unique setup. These specs can also change on each corner of the car and driver to driver.
Chevrolet recommended alignment settings:
Front (with power steering)
*Caster +2 ¼ degrees +/- ½ degree
*Camber +3/4 degree +/- ½ degree
Toe-in (total) 3/16” to 5/16”
* Must be within ½ degree of opposite side.
Caster & Camber Information
Increasing the number of rear shims in relation to the front increases caster. If static camber is already correct, generally speaking you’ll need to split the difference to increase caster by adding about half as much shim at the rear while removing that approximate amount at the front. However, the ratio isn’t linear as the CA shaft rotates further from parallel with the chassis, and you want the upper ball joint’s distance from chassis CL as seen from above to remain constant to maintain a given static camber. Uneven caster will pull to the side with less.
If caster is already correct, pretty much add or subtract the same amount of shim front and rear to adjust camber.
