The present invention is a wheel alignment gauge for checking the ‘toe’ and ‘camber’ of the wheels. The gauge can be used with the vehicle on the ground. The gauge uses three identical magnet-ended extension rods which are inserted through the vent holes or spokes of the wheels. The rod's inboard ends magnetically attach to the disc brake rotor surface leaving the outboard ends clear of the vehicle's wheel and bodywork. Flat plates rest on the ground and magnetically attach to the outboard ends to create a plane parallel to the rotor and wheel. Laser-ended alignment arms magnetically attach to the plates, are level, and have forward ends that extend beyond the front of the vehicle allowing the lasers to project ate target sheets centered on the lasers. Each arm also has a perpendicular location arm that contacts the front of the wheel (or rotor when the wheels are removed). The laser's dots provide a off-center measurement, which, along with the arm's spacing, one can calculate the trigonometric SINE of the wheel's angle. The gauge can be quickly changed from vertical to horizontal for camber or toe measurements respectively. If adjustment is required, the vehicle is raised on its suspension, the wheels are removed and the gauge re-attached to locate on the rotors to direct alignment adjustments.

The invention provides a self compensation floating swing arm independent suspension system, comprising a self compensation floating swing arm independent suspension device and a centrifugal force control scissors-type anti-roll bar device.

The self compensation floating swing arm independent suspension system has a simple structure, excellent performance, and low cost, and is easy to realize.
