I have the Akebono Kit on my 2006 350Z, and I love it, just the stoptech rotors I have are SOOOO heavy. This would be an awesome alternative, but just the price is way out of my allowance. I paid almost the same price for my full (front and rear) akebono complete kit.
I would definitely consider these if the price was right. But until then (or when there are other options available) I will stick with my stoptech slotted rotors.
