I have them on mine, had the car over two years now, no issues so far.
Performance, can't say I have had many operrunitys to push them to the limit but have never experienced fade on them even when I was tanking down berridale.
The positives are next to nil brake dust, weight saving
, longevity assuming they don't fail and they look the nuts.
The negatives, when you first move the car on A damp morning there is break squeal when dragging the brakes reversing for example and the eye watering cost of replacement should you need too.
I would remove them and fit steel discs should they ever become an issue.
