12mm Camber Bolt,Universal Vehicles Steel Four Wheel Alignment Adjustable Cam Bolt Camber Kit

I needed to adjust the camber on the front wheels of my Opel / Vauxhall Astra H as it was wearing the tyres on the insides.I replaced the top strut bolt on each side with one of these camber bolts and it gives a small amount of adjustment. It's a bit unclear how you are supposed to line up the cam and the tabbed washer but maybe I'm overthinking it. I used a digital angle cube to measure the camber.Local garage alignment places generally qon't adjustment camber at all, so it's good to be able to do it myself and get a longer life out of my tyres.These bolts have 12.0 stamped on them, so they are very strong. When I was tightening them, they certainly felt strong with no signs of stripping the threads.
