Does that work for both AWD and RWD?

 

Yes. I think Mtrbtvr6 is running those #s with success on his awd TT with NT01s. He’ll probably chime in.

 

Im running -3 degrees front, and -2.0 rear AWD and it works great! Im not on the NT01s yet but in the process of buying them in 245/315 flavor and will run them all next season with AWD. I havent heard of any issues with those sizes, but I track the car pretty frequently and will find out pretty quickly if they dont work. I am currently on 225/295 Yokohama AD052.

 

Ran this with PSS10s, Tarett camber plates, drop links and LCA's.

And with the JRZ's:

Going to more neg next alignment

 

Those are almost my exact numbers that im running. What spring rate? Im currently experimenting with 6 Comp 10 rebound front and 6 Comp 12 rebound rear. Helped with AutoX lower speed oversteer.

 

Running 700/800, will be going up this winter when I pull them for a rebuild & revalve.
Got 2.5 seasons before they started leaking.

I've been running them almost full stiff on the track this past year.
The track has been repaved, shocks are more used and I'm a little faster.

Here's another one to think about that I got from a friend:

 

Once you go to NT01s Ryan, you can increase neg camber another 0.25-0.5 degrees both front and rear.

 

Thanks John, planning on it for sure. I will have a second set of wheels this year so I can be more aggressive with the camber settings that the NT01s like. Oh and that rear rebound adjuster that froze, is still perfectly fine. Ive adjusted it a few times now with no issues. That was so strange!

 

These are honestly great tires for the price. But if you are looking for more versatile tires - but still track focused, go with the Yokohama A052s. They were on back order when i needed a replacement set, and decided to go with Nittos.

Street Use:
Rain: Honestly, scariest drive back from Lime Rock Park to Boston MA.
Dry: Decent, no drama
They are by far, the noisiest tire i have ever had. I have 245 fronts and 305 rears, and they literally create this booming-echoing noise even at 20-25mph.

Track:
If i were to do it all over again, i would get them heat cycled from Discount Tire Direct, they take awhile to "scrub in" (if that's the word), but once they do, traction is as good as the Yokohama A052.

I recommend the A052 overall because its PS4 quiet, and actually has above average traction in the rain. Hence a more versatile tire for those who dont trailer their car to the track, or wanna drive their cars as a weekend toy sometimes.

 

Any suggestions on hot tire pressure to start with on the 245 315 combo?

 

Ive run two full sets now of the Yokohama, and I completely agree. As a dual use tire its as good as ive found. Makes even less noise than the RE71R with similar grip level, but takes heat from a track better than the RE71R. They are staying on my stock wheels for AutoX/street duty. Nitto NT01 for track next year, im going to try them out. Just wish I would be able to run RWD and do the 305 like John suggested. All in due time.

 

32-33 HOT pressure. Make sure to check them mid session to get the most accurate reading. Or immediately after the end of your session pull over in the hot pits to take the temps. Don't wait until you get back to your pit area, they've cooled off quite a bit by that point.

 

How do your lap times compare with the NT01 vs A052? I'm a regular NT01 user but I'm open to new options.

 

It feels to me like the tires are rolling over at these temps, and they feel better in the high 30s. Anyone else experience that? My specs on 235/315:

 

What R888R failures? That's the first I've heard of that.
