Using this K - Tuned rear camber kit is easy. First, make sure your car is parked on a flat surface and the wheels are straight. Locate the old bushings and remove them carefully. Then, install the new bushings from the kit. Adjust the camber within the range of - 2.5 degrees to + 1.5 degrees according to your driving needs. For street driving, a smaller adjustment might be enough, while for racing, you may need a more precise setting. When installing, ensure all parts are tightened properly to avoid any loose connections. As for maintenance, regularly check the bushings for wear and tear. If you notice any cracking or excessive looseness, it's time to replace them. Also, keep the parts clean to extend their lifespan.
