BMW Alignment Specifications
BMW automobiles have a sterling reputation for durability and overall customer satisfaction, according to Pelican Parts. In addition to engine and electrical components, alignment specifications are important to keep your BMW physically balanced and safe to handle. If your steering wheel seems misaligned or your car veers to the left or right it may be time for an alignment adjustment. Standard BMWs may included "nonadjustable" alignment components, so see an automotive professional with questions or concerns.
BMW Camber
Camber alignment specifications are included on the front and back end of a BMW. A zero camber design means tires sit perfectly upright on both the left and right side of the vehicle, making tire pressure evenly distributed. Negative camber indicates tires that tilt towards one another while positive camber ers to tires tilting outwards. BMWs may require various manipulations of camber, depending on the model. A BMW 3-Series, for example, best handles on standard street conditions and vehicle turns when the camber is slightly negative.
BMW Caster
Caster relates to steering alignment. Zero caster ers to a steering axis that, when angled vertically, provides for straight driving. Positive caster indicates strut angling toward the back end of the vehicle, while negative caster means strut angling toward the front. BMW caster --- as with camber --- varies depending upon the model, although most models require 3-9 degrees of angle variety. Front-end and back-end caster can be analyzed independently.
BMW Toe
Toe-in ers to tires where the front edges are angled closer together than back edges. Alternatively, toe-out means tires that angle into each other more on the back edge. Toe helps cars handle while making wide and sharp turns. Toe is adjusted by manipulating the tie rods. Minimal toe-out calibrations may be required for some BMW models, although tires with "neutral" toe are usually most reliable.
