Number one being the piston knock back. For those that don't understand I will explain. You drive hard through a twisty section of corners and exit and you are now on a straight. The g-force through those corners has now created a nice gap between the piston and pads, and when you brake hard after the long straight you are on the pedal will not be as consistent and there will be a slight delay before you are getting into the initial bite of the pad. With the Spoon calipers (and any other good 4 piston caliper) this just doesn't happen.

This is something I have experienced at every single event I have been to at Buttonwillow and Thunderhill West, and for the past few years in the mountains. I have been on 2 different pairs of OEM calipers and it was consistent on both of them.
Fixed caliper with 1 piece rotor can definitely experience knockback due to various things flexing. But I don't think the S2000 suffers from that really even if it had a fixed caliper with single piece rotor, the upright and hub is very sturdy it is more a matter of the whole god damn floating portion of the caliper moving around. I will edit my post accordingly. All I know is the brakes would consistently feel like crap once a lot of heat was put into them, and so far that just isn't happening with Spoon calipers. The initial pedal feel is always consistent and generally provides more feedback.

I was going to pick up a set of these for the Weds but I wanted to have a fair comparison between my staggered setup. Did you measure the width of yours by chance? If you do let me know what they are. They were listed as being slightly narrower than the RE-11A I think. The AD08R is definitely a little wider than the RE11/RE11A.
If I get the CE28Ns in time I think I will get some RE71Rs so I can compare them with the AD08R back to back.

Great review!
I look forward to trying out my new sq setup w/ the stoptech kit at an event next month. Unfortunately the car's been sitting and I haven't had time to tinker w/ it or drive it, so minus some light bedding of the new pads, I can't comment.
I had a similar issue in terms of finding consistency w/ the OEM brakes w/ 225's up front, especially at 100+ mph brake zones. As the pads got towards the end of their life the issue worsened. I had some strange and uneven pad wear, and I never bothered to really find the exact culprit. The "slop" you mentioned sounds like a good possibility and it's just a limitation of the oem sliding caliper. I hope my experience is as great as yours. More responsive turn in would be great as well. On the staggered setup on track at times there'd be a small delay between turning in and the car responding.
Great detailed review!
