What does this kit actually adjust?

Front camber at the lower strut mount. Turning the cam bolt shifts the strut relative to the spindle to add or remove negative camber.

Only if your front lower strut mount takes a 14 mm cam bolt. Check your vehicle's bolt diameter and mount style before ordering.

Do I need a professional alignment afterward?

Yes. The kit gives you the adjustment, but camber and toe should be set and verified on an alignment rack.

It uses standard hand tools, so a confident DIYer can fit it. Plan on supporting the suspension and getting an alignment after.

It is commonly used to pull camber back into spec after lowering, as long as the resulting range covers your target setting.
