Picture Perfect Wheel Alignment


Our Hunter DSP600 digital imaging technology uses four precision cameras in the aligner tower to measure the position and orientation of reflection targets mounted on each wheel of your car.

The aligner then uses the information from the precision cameras to calculate your car’s current alignment measurements. We then re-adjust the camber, caster and toe to get the proper adjustments and return the alignment angles to the manufacturers specifications.

Improper alignment is a major cause of premature tyre wear Over the years, a properly aligned vehicle can add thousands of miles to your tire life.

How do I know my wheels need aligning?

  • Excessive or Uneven Tyre Wear
  • Vehicle Pulls to the Left or Right
  • Steering Wheel Vibration
  • Steering Wheel is not Centred

How often should the alignment be checked

  • Every 12,000 - 15,000 miles or at least once a year
  • You knowingly hit a kerb or pothole
  • New tyres are fitted
  • Steering and suspension components are replaced

4 Wheel Alignment vs 2 Wheel Tracking

2 wheel tracking only does the front 2 wheel and not the whole car and as a result the car may still pull left or right and the rear tyres will still suffer from premature failure.

4 wheel alignment ensure all 4 wheels on your vehicle are aligned and that the ‘Thrust Angle’ is pointing straight  ahead, only then will the car drive in a straight line.

About your Print Out

When you visit you will receive a print out with the alignments BEFORE and AFTER the adjustments.

The BEFORE readings are how your vehicle was running on the road and RED boxes show which components were out of alignment. Components that are within manufactures specifications are shown with GREEN boxes.

The AFTER readings are how your vehicle is setup once the technician has made the adjustments to the manufactures specifications.

Camber is the angle of the wheel in relation to vertical axis of the vehicle when viewed from the front or rear. With positive camber the top of the wheel leans out from the vehicle and with negative the top leans in. With excessive camber the tyre will wear on one side and this leads to early failure.

Caster angle is the angle of the wheel in relation to the vertical axis of the vehicle when viewed from the side. The larger the caster angle the more stable the vehicle is in a straight line but this also increase the effort required to turn the steering wheel.

Toe or Tracking is the angle of the wheel in relation to the centre line of the vehicle when viewed from above. Excessive 'Toe in' or 'Positive Toe' will cause your tyres to wear on the outside edge, were as 'Toe out' or 'Negative Toe' will cause your tyres to wear on the inside.

Thrust angle tells you if the vehicle will 'crab' or move sideways as it travels forwards.

Steer ahead is the direction the vehicle will take when left to steer itself on a flat surface and therefore how much the vehicle will pull to one side.
