On these LH body cars, camber is not adjustable. Neither is caster. Those angles are preset by the suspension geometry. However, specifications for them ARE published. Generally, if either of those two parameters are out of spec, then it's likely something is worn or damaged and needs to be replaced.

The only adjustable parameters are to the front and rear toe but specified as "Total Toe" - see note below.
The alignment specs are as follows ...

ALIGNMENT SPECIFICATIONS AT VEHICLE CURB HEIGHT
A. FRONT WHEELS

1. CAMBER
   Acceptable -0.6° to +0.6°
   Preferred +0.0°
   Side to Side Differential
   Acceptable 0.7° or less
   Preferred 0.0°
2. TOTAL TOE - Specified in degrees. See Note Below
   Acceptable 0.4° in -to- 0.0° out
   Preferred 0.2° in
3. CASTER* (reference angle)
   Acceptable +2.0° -to- +4.0°
   Preferred +3.0°
   *Side to Side Caster Difference not to exceed
   Acceptable 1.0° or less
   Preferred 0.0°

B. REAR WHEELS

1. CAMBER
   Acceptable -0.6° -to- +0.4°
   Preferred +0.1°
2. TOTAL TOE** - Specified in degrees. See Note Below.
   Acceptable 0.2° out -to- 0.4° in
   Preferred -0.1° in
   **TOE OUT when backed onto alignment rack is TOE IN when driving.
3. THRUST ANGLE
   Acceptable -0.15° -to- +0.15°

Note: "Total Toe" is the arithmetic sum of the left and right Toe settings. Positive is Toe-in. Negative is Toe-out. Total Toe must be equally split between left and right wheels. Left and Right Toe must be equal to within 0.02° (2 one hundredths of a degree).

If the car is stock then I would run the caster at .05 higher on the right than the left to adjust for the crown of the road. the front alignment looks good other than I am not sure which one is camber and which one is caster. To adjust the rear camber on these cars you have to have a camber kit. From the angle I am seeing you don't have a camber kit. Also the only way to adjust caster on the civic is to shift the sub frame.

the camber has to be adjusted on an wheel alignment machine. after that is adjusted, then the "toe in" is adjusted. You cant adjust one with affecting the other. but camber has to be done first.

It does sound like you've got an alignment problem. The only solution to that would be to take it to a shop and get it aligned.

Before making wheel alignment adjustment, perform the following checks:

1. Tires should be equal in size and runout must not be excessive. Tires and wheels should be in balance, and inflated to manufacturer's specifications.


2. Wheel bearings must be properly adjusted. Steering linkage and suspension must not have excessive looseness. Check for wear in tie rod ends and ball joints.
3. Steering gear box must not have excessive play. Check and adjust to manufacturer's specifications.
4. Vehicle must be at curb height with full fuel load and spare tire in vehicle. No extra load should be on vehicle.
5. Vehicle must be level with floor and with suspension settled. Jounce front and rear of vehicle several times and allow it to settle to normal curb height.
6. If steering wheel is not centered with front wheels in straight-ahead position, correct by shortening one tie rod adjusting sleeve and lengthening opposite sleeve equal amounts.
7. Ensure wheel lug nuts are tightened to torque specifications

Ride Height Adjustment

Before adjusting alignment, check riding height. Riding height must be checked with vehicle on level floor and tires properly inflated. Passenger and luggage compartments must be unloaded. Bounce vehicle several times, and allow suspension to settle. Visually inspect vehicle from front to rear and from side to side for signs of abnormal height.
Measure riding height. See figure. Riding height between left and right sides of vehicle should vary less than 1′ (25.4 mm). If riding height is not within specification, check suspension components and repair or replace them as necessary.
Wheel Alignment Procedures

Honda recommends using commercially available computerized 4-wheel alignment equipment. Follow equipment manufacturer instructions to obtain vehicle alignment settings. Use following procedures for necessary adjustments.
Civic Camber Adjustment
Compare camber settings with vehicle manufacturer recommendations. If camber is incorrect, check for bent or damaged front suspension components. Replace faulty components. Recheck camber.
Civic Caster Adjustment
DO NOT use more than 2 shims. If more than 2 shims are required to adjust caster angle, check for bent or damaged suspension components.
Compare caster settings with vehicle manufacturer recommendations. If caster is incorrect, check for bent or damaged front suspension components. Replace faulty components. Recheck caster.
Civic Toe-In Adjustment

1. Secure steering wheel in straight-ahead position. Measure front wheel toe-in. If adjustment is needed, loosen tie rod lock nuts. Turn both tie rods equally in the same direction until front wheels are in straight-ahead position and toe-in reading is correct. Tighten tie rod lock nuts. Reposition tie rod boots if twisted.
2. Ensure parking brake is released. Check rear wheel toe-in. If adjustment is needed, hold adjusting bolt on rear compensator arm and loosen lock nut. See figure. Adjust rear toe-in by sliding rear control arm until rear toe-in is correct. Install NEW lock nut, and tighten it while holding adjusting bolt.

hope this helps you out.

Since the rear wheels do no steering, there is no toe in or camber adjustments. Why do you believe you need these to be adjusted? Has the car been in an accident and the rear suspension is out?

There is likely an eccentric bolt on the lower contorl arm. The one on the arm closest to the bottom center of the wheel hub is the camber adjustment, the other eccentric is the toe adjustment. You really should have it aligned with a computerized alignment machine. Changing the rear camber changes the rear toe and vise versa. It would be nearly impossible to get both within an acceptable range without the proper equipment. You can crudely measure rear toe using a tape measure but you won't know what the thrust angle is and that could cause some serious alignment issues.
