I like it. It is challenging to set-up, but good once it gets going.
One issue that I found is that the ARS makes the rear really narrow on the XRAY, so I have found that adding shims to widen track width between the wheel and the hex helps make the car much better. The car seems to just roll too much when set up very narrow.
Personally I have it set up to where it has close to Zero toe gain/loss. I like it because I can set my car to have exact rear toe and I can also use fine increments of it. However the Toe gain/loss made the car inconsistent. I set the pills at max width RF and 0.5 in on the RR. The rest of the toe I add with the turnbuckles. I go between 2.25 and 2.5 degrees of rear toe most of the time and also have a 0.5mm shim raising the RR and RF Suspension mounts from the center pill position. (Also helps control rear toe)
Now does it make the car better or worse? Both. Set up correctly is a nice addition that can simplify the rear end adjustment and unlock unlimited rear toe settings. When set up wrong, as Syndrome stated, can make the car feel like its broken.
