What rear sets do you use? In the market for a set..

Not exactly important, I picked up a 2011 zx6r, rear sets on the list for upgrades. Anyone have any suggestions for these expensive pieces of hardware? Pros cons? My budget is 600 or less.I'm also in the market for a bunch of other items (Exhaust, engine protection, PC/Bazzaz, number plates).​Thanks in advance! via /r/Trackdays https://www.reddit.com/r/Trackdays/comments/aq2mdu/what_rear_sets_do_you_use_in_the_market_for_a_set/?utm_source=ifttt
