HJT,
I do all my wheel alignment at home for the track car using simple home-made laser beam alignment tools. To be able to set the toe and camber for the rear tires, you must be able to read or observe the change during the adjustment process. This is how I do my alignment from condition 'A' to condition 'B'.
Toe and camber setting for initial setting (condition-A):
1. Lift the car or just the rear end off the ground.
2. Remove rear tire.
3. Check the vertical and horizontal planes of the brake rotor. I use a tool that has vertical and horizontal laser pointers attached to the brake rotor. These laser beams will point to the ground (camber) and to a wall (toe). These laser readings are specific to condition-A. Place a masking tape to where these laser beams projected and this is your initial setting.
4. If you need more camber, adjust the beam to move slightly outward (away from the center of the car) using your reference point on the floor. Same with the toe , moving the laser beam outward would decrease the toe reading.
5. Tighten the adjusting nuts and bolts, take the final reading and drop the rear to the ground. The rear of the car would be higher than normal and allow the car to settle. Or drive it around the blocks to bring the ride height back to normal.
6. Measure the new toe and camber readings.
You could get as much as 2.75 deg. but not all the time. 2.5 degrees is most you could get consistently for both sides. HTH.
