Their rear toe links are very nice. Look to be top-quality parts/materials and easy adjustment.

Some of their other parts I can understand the offering, but in limited cases, like the adjustable front radius arm (they call it "Tension Rod"; GM calls "Ride Link") for caster adjustment and rear adjustable trailing arms for camber. The thing with some of this is that if you mess with one, you end up effecting other alignment specs (like camber+toe), so in end you end up needing all/most of the components (mostly speaking to the parts that move in more than one dimension).
