Safety aside, you'll use up your heat cycles doing that. The R1 seems to give 10-15 heat cycles before getting hard. The NT-01 doesn't have this problem, staying nice and soft until the tread is gone. I think the NT-01 is a better DE tire but they're definitely not as grippy as a new R1.

Hmmm, sounds like heat cycle them out by driving to and from the track. Since I mostly due DE events, I'll stay with the NT01s for the time being. My skill level is intermediate/high intermediate so I'm sure the NT01s are more than fine for me.

For a fairly sticky tire that costs $1,000/set delivered, and virtually unlimited heat cycles, they are a great value.
Interesting. What pressures do you use?
Wonder if it might have anything to do with Cayman v. 911?

34F 37R. Can't comment on 911 vs. Cayman. I don't know why that would make a difference.

Dave,

Andrew is looking into some Hankook Z214's for me as my Nittos have close to 60 heat cycles on them,although they still have lots of thread on them they don't come in the front sizing that i'll be using next year.
From what i hear the Hankooks are a compromise in between Hoosier and Nitto,not sure on ease of Canadian availability though ...

I'm sure somebody can post some feedback on the Hankooks ???

Cheers
Phil

Question for you guys...can I put 315/30/18s NT01s on my 997.2 GT3 instead of the 305/35/18s for the rear wheels?

There were several guys who did it on 997.1's, not sure about .2's

The fear is they will cause compatibility issues with the ABS system since the rears are a good bit shorter than OEM diameter.

I am sure it is setup dependent, but I am wearing out the outside of the front tires despite -2.5 with NT-01, so more likely will go with -2.8 next. Just another data point.

My NT01's were wearing the outside shoulder as well with -2.4 front camber,and that's with a 2700 lb car ...

I flipped them and went with -2.8 front camber and the wear in nice and even now !

Yeah, I will experiment with -2.8 next.. and see how it works.. can do more if needed in the future!

I think car / driving style, suspension will all determine where camber ends up.

I'm at -2.9 / 3.0-ish on the front of my car and it's still not enough, While I'd like a little more front mechanical grip and think I could get it by going -3.2-ish in the front I'm getting maximum life out of them at -2.9 and flipping the tires on the wheels at about 25 heat cycles PLUS I'm really happy with the balance of the car overall right now. Just slow, mechanical grip corners where I wish I had a little more front grip.

Andy,

I think you are going a bit faster than me that's why you are still wearing more on the outside despite the camber! (I am currently in the White run group only..) Do you run stock spring shocks, or?

JRZ triples - 600 lb springs

The stiffer the springs, the less camber you need, since the car would lean less..

One of these days, I will need to put in some new shocks/springs.. ! I am still running stock setup.

Yeah, not sure I want to find out if the ABS goes nuts with the different wire size especially when I'm going down a straight at over 120mph...I would not want to lock up the brakes!
