I just took my nt01 off after just one trackday and my rear left tire has a tread splice exactly as what is discussed on this thread. It is not as bad as some of the others but i'm sure it'll get worse.. I'll be calling performance tread on Monday..
Curse you nitto! I think I'm switching to BFG R1...
