ordered a pair today for the s14, should be entertaining.
i think the big issue for these "semi slicks" yes i know they not real ones, is heat cycles, the RE11 I tried were great, for maybe 5 sessions then were gone for good.
KU36's maybe 5 track days.
I got around 15 on my RSR.
R888 real semi's never had a heat issue, but naturally wore out b4 the heat killed them.
thus why AD08's so good, they handle the heat better than the rest.
