All manufacturers recommend you have a digital or 3D 4-wheel alignment. With systems like ABS, traction control and cruise control all four wheels need to be aligned. Wheels and tyres are getting bigger and wider - which ultimately means more expense - it is vital to get your alignment checked. We would recommend annually in most cases. If you live out in the countryside where there are plenty of pot holes, and bumps, an annual check would certainly be wise.
Our Alignment machine use cameras and targets attached to each wheel which create a 3d image of the wheels, and where they are pointing on every axis. Conventional methods of checking the tracking only measured the front, toe in and toe out, angles. This was fine 20 years ago, but not anymore. So, wherever you take your car, make sure you have a 3D 4-wheel alignment!
