The rear sets are pretty awesome: the bike should have come with them from the start, cornering is pretty much limitless now. Longer rides are more of a compromise though because of the height. You get used to it though.
The center stand foot sits directly under the footpeg so if you think your centerstand is limiting you, I beg to differ.
At the last trackday even with raised and shorter pegs, I could still drag a toe slider no matter how much I hung off. If that happens now, I did something truly wrong in the corner.
The track grips help with the rearsets because you can no longer use the frame and knee bumpers to hold you up (different position). You can clamp down with your thighs now and can use the tank as an anchor point when hanging off or moreso when braking.
