Why use offsets?
Offset upper shafts are used for several reasons
• Repair alignment because of frame damage or frame sag.
• Repair alignment do to ride height change
• Fine tune alignment for racing or performance applications
For most conditions, offset shafts are used for frame issues. They generally give you about 1-1/4 degrees of additional adjustment. However, in the performance world, they are perfect for getting the best possible alignment using stock suspension.
Tech Tips:
One of the keys to better tire life and performance on these older muscle cars is to increase caster and induce some static negative camber. These older cars roll positive, which means as the tire goes up into the fender, the tire tilts out of the fender at the top and increases outside tire wear.
Therefore, by changing the static factory alignment settings from 1/2 a degree positive camber to a 1/2 of a degree static negative camber, dynamically you will reduce outside tire wear. Increasing the caster will also give you better tire life because of the camber change do to the combination of the spindle inclination angle and increased positive caster.
Note: Caster is an indirect wearing condition where camber is a direct wearing condition. So increasing caster is going to help straight line stability, corner entry, and tire life.
