| I reckon so.
I had them on my SPS and R and I reckon they are an improvement over the standard SPS/996R disks.
However, I changed the disks at the same time as fitting a race brembo m/cyl, twin braided hoses and Bendix pads on both the R and SPS, so I couldn't single those out as specifically being better.
As an idea of costs, I sold mine recently on ebay for £190. I've seen them go for £180 - £260 s/h.
