IB DinanS2++ e60m5 6MT, Dogleg s38b38 e28m5 TT/ST3, e30 TT/ST4
I was having air pressure challenges. I started at 28 cold and ended up over 40 hot. I know I took out too much, just by the wear pattern. Willow Springs puts a beating on the DS front tire. The rears were perfect. I'm running a 17x8 square 245/45.Maybe? When taken beyond their limit the NT01s feel like the shoulders start rolling / skipping / jumping. No one will keep the tire doing that so it's more of a feeling rather than a wear pattern. I suspect it may be related to them being pinched a bit on 9.5 wheels. What wheel width are you running? I see your fronts wearing all the way to a line on the sidewall (same as mine) instead of the TWIs as your rears.
RC-1 is on my short list for the e28. A few of my e46 guys love them -- and they are cheap(er) than Toyo RRs. I am still running Yoko AD08Rs on the e60. Nankang CR-1 is also on the short list.
This is where I get Toyo RRs for the e30:
