Thanks guys for sharing your intel. Sounds like for .5 degree of negative camber reduction (done on both sides of course) that it changes the total toe by 1/16" in the toe-in direction. This is good know. So if you started with 1/16" total toe-out and -2.5 degrees camber for track and reduced the camber to -1.5 degrees for street, then the toe would change from 1/16" total toe-out to 1/16" total toe-in.

I've been through 8 sets of Cup2's and 3 sets of NT01's in roughly the same amount of track time. I am a huge fan of the Cup2's...for maybe 2 run days. After that they fall off very quickly and I sell them with nearly perfect tread. On fresh (or seasoned) NT01's I cannot run within 2 seconds of the MPSC2 when the cups are in their prime. However, with the nittos I run consistent laps throughout a session for pretty much the life of the tire. Knowing my baseline, I plan accordingly. If I need a fast lap, I don't mind changing the setup between sessions.
I will be on the Goodyears next month and I am hoping to get similar performance to the Cup2's. If so, that will be my go-to tire for when times matter. They are significantly cheaper. Obviously camber plays a large role in the longevity conversation, but if I could offer one thought on the subject that might resonate, it is that if you push this car to its limits, you will not get more than 20 good 2min laps out of an R compound before seeing .5 seconds added to your times in quick progression. I'm talking about 10/10ths with a very capable driver. The car is too heavy to maintain peak tire performance, if longevity is also your goal. That's why the Nitto's and their older technology are still the best bang for your buck. This whole discussion is really about trade-offs, imho. Now if you are not the guy who is chasing a PB every time you hit the track, I guess your results may vary. I'm just not that guy. I'm there to drive. I'll have NT01's, Cup2's and RE's at MRLS this weekend. I plan to try them all in the two days. Can't wait to try the GY's

It sounds like the lap time delta between Cup 2s and NT01s on a heavy and more powerful car (ZL1) is bigger than an SS or C7 and I think it makes sense since the heavier/more powerful can benefit even more with higher grip. I don't think I am a "very capable driver who can drive 10/10ths" by any means but I noticed that after 3-4 hot laps with NT01s they also start falling behind their peak performance, with lighter cars they felt a bit more consistent for sure. Of course inconsistency is not as bad as any street tires but it's still there due to physical boundaries of heavier car. I look forward to hearing from you on your back to back comparison between those tires at MRLS

I can relate completely to your comments on the Nitto and Cup 2's, as well as the wear rate on heavier cars. Looking forward to hearing more on the 3R's. We know they're cheaper, but let's find out if they are faster wearing in exchanger for how much faster times. I just put the cover on my ZL1 while I wait for spring. In the meantime I just ordered wheels. |

Apologies for bumping an old thread, but it made more sense than starting over.
So here we are a year down the road, and I'm hoping more folks can post their experience with the Goodyear 3Rs in comparison to Cup 2s and R888/NT01. My experiences with RE71 and NT01 is similar to the others posted, but on much lighter, low HP cars. I'm getting ready to put together a track wheel/tire combo for our ZL1, and am trying to decide which way to go... leaning heavily toward NT01, but I'd like to hear more about the 3Rs... |

The 3R is far superior than the NT01 on the Camaro platform. I recently ran 315/325-18 NT01's, tested them with multiple pressures using a tire pyrometer and could not get them to work. They were roughly 2-4 seconds SLOWER than the 3R. Turn-in is soft and there is a dramatic lack of bite up front with the NT01. They could be a good tire if you want something to just lap in and don't care about times or overall performance. But I will not be running them again, not a fan.
I ran a set on my SS 1LE a year ago with similar experiences.

Great input on the 3Rs. Thanks!
How 'bout longevity? Are the 3Rs closer to R7s or NT01s on the wear spectrum? |

I have a new set of 18's just laying around right now because I was so unhappy with the performance of the Nt01's, which is one of the few tires that comes in proper sizing for 18's. Until I can find a decent set of 18" tires I will be going back to stock 19's and 3R's. Except, I will run 2 sets of front wheels and swap fronts after each session. This way I get about 14 sessions per "set" .

Yikes!
Is excessive inside wear an issue with ZL1 as well as the ZL1 1LE? This isn't our primary track car, but 6-7 sessions isn't even two trackdays... |
