I planned to be the guinea pig with the NT-01 setup, but when ordering time came and it was time to pull the trigger, I...... ordered NT-01 245/40/18 fronts and NT 555RII 305/35/18 rears. The 555RII's are Rcomp, 100 rubber for road course tracking, just like the NT-01's. The overall diameters are correct. With the NT-01 rears, they are starting out a tiny bit too small, but then when the rear wears faster than the fronts, the front/rear OD incorrectness will get worse. I don't want to risk driving 8 hours to a track just to be in limp mode the whole time. I will report on how the NT01/NT555RII setup works.

I agree...I'd rather have the 305/35/18 over the 315/30/18.
I tried with R888 245/305 and then thought 255/315 would be better and it was not better. The car felt a little better with the 245/305 combo. But at this point I'd take whatever Nitto would make that would be the correct fron tto rear overall diameter ratio for a 997.
On the other hand you 997.1 and .2 GT3 guys can turn off PSM and run the 245/315 size with out issues. My GTS is Carrera based PSM and can't truely be turned off.

I run the NT-01 on my 2007 GT3 in 245/315 sizes with no problems. Actually
like them better than RA-1. Goog thing as I am on my last set of RA-1s. Have a second set of NT01 waiting in the wings. Last DE used the Toyos as the track was wet/rainy. I will need to find some tires to replace the toyos when I use them up as I prefer the toyos in the wet.

Where's the best place to order NT-01s? Discount Tire? Big O?

would be nice if somebody could test bfg rival against nt01 on the track and share results.
i am not sure how an utqg 200 tire can compete with a true r-comp like nt01 but who knows.
