Frequently Asked Questions

How do string lines work for wheel alignment?
String lines are stretched parallel to the vehicle's centreline at wheel height, creating a reference datum from which toe, thrust angle, and four-wheel alignment can be measured accurately. B-G Racing string lines use machined grooves in the stringing bars to ensure the string is always positioned consistently, giving repeatable results.

Do I need hub stands to use string lines?
No — string lines can be used with wheels and tyres fitted. However, combining string lines with B-G Racing Hub Stands gives the most accurate and repeatable results, as hub stands eliminate tyre and wheel variation from your measurements.

Is a carry bag available?
Yes. A black nylon carry bag (BGR203) is available separately to store and transport the complete string line kit.

Is this a genuine B-G Racing product available in NZ?
Yes. Harris Race Radios is the official Australasian distributor for B-G Racing. Note: this item is bulky and heavy — contact us for a freight quote before ordering.
