I'm not Vorshlag but have I used and loved their camber plates on and off track, year round daily driver, for about 90,000 miles. I bought them pre-assembled as part of their StreetPro package so install was easy. They are over-built and super sturdy. If you are buying just the camber plates you will need a spring compressor and the same tools and skills as doing a front strut replacement. No unique challenges in my experience.
Changing from street to track? For street, as said, make sure both wheels are in the air. Put camber plates in max upright position and set front toe to zero so you don't get weird or excessive tire wear. Then on track days, both wheels in air, just move to camber plate to max negative camber (the top of the strut will hit the inside edge of the strut opening; you can back it off a smidge to avoid rubbing), enjoy the day, and put back to full upright when done and going home. 5 minutes, most of which is jacking the car.
A side benefit is that because of the steering geometry when you move the cc plates to max neg camber you also create a toe out alignment, which makes for nice sharp turn-in on the track. Win-win.
When I asked Vorshlag how much negative camber I should use for track days, the guy on the phone laughed and said "all of it." That is what I've done and it's worked great. CC plates are an awesome mod. Enjoy.
