Now im down to the NT05R,NT555R and NT555RII,what some comments on these.
NT05R's being that it is for highway pulls. These tires hook great. Do not drive in the rain I don't care what others have said you WILL be all over the roadOccasionally but cruising.I do the speed limit or a few mph above.Mainly highway and accelerating.
Well im not going to drive car in the car.However if i go on car events how will i get home if its raining?
So what are we talking difference in NT555R and NT555RII?
Also how do regular NT05s play into the mix?

I just don't see any street tire gripping for you at 615 rwhp on the rear. My suggestion to that would be get NT555R's up front and do the 555R drag radials out back. Then you have good front end turning and can hook up from a slow roll. It may not handle quite as good, but still fairly well. And it does work, I've seen guys do this on cobra's at local autocross events and do well.
i think a 305/35 or 315/35 18" would be a good choice. Those are 26.3" tall tires and that will automatically help you plant that power level versus a shorter rear. Then all you have to do is decide if you want a 100 tread rated tire or are willing to cope with the negativities of a 0 rated tire. I chose the 0 rated toyo tq dr's in 315/35 and it plants the power damn good
With that power you dont have much choice then. You need an R compound tire. Street tires are just not gonna cut it. Now this is just my opinion so take it for what its worth. I have the NT05's in the front and M/T ET streets in the rear. the front is 275 35 18 and the rear is 305 35 18. The only reason why I didnt go with the NT05R's is because it is a taller tire at 305 45 18 and I dont want my ABS light going off. I have no complaints. You can do what the other member suggested with the nt555r and the 555r DR and keep the same tread pattern. When I was at 605 I had zero grip with a street which is evident in my 1/4 mile time. With DR's it was a totally different story. I was kicked off the track cause I didnt have a cage. If you are wondering why I went to the track with street tires is because I wanted to play someone that I knew was filming me lol. :burnout:
555r II`s are made for open track/ auto-x tire ( i have a set & i like them )
i have had some Azenis also and they were great @ the auto-x also
