Nankang CRS vs Michelin Cup 2N - Porsche GT3 992 Tire Test @ Spa Francorchamps

[@PROofHAPPYWHEELS]

The on-track data is super interesting, thank you for putting it at the bottom of the screen whilst doing your laps. Really awesome video, if you guys keep these up semi-consistantly, I can see your channel growing very large.

[@wdp_racing]

@@PROofHAPPYWHEELS Thank you for taking the time to comment and for the productive input! Something to keep for the future and hopefully, weather allowing before the end of the season we will come up with another video!

[@slowfrs]

We've had the Nankang CRS tires in our country for a few years now. They are the best 200TW tires for in our time attack series besides the Yokohama A052. 23:00 Yes! Good observation - we find that most cars need to be set up with more negative camber to utilize the CRS to its full potential.

[@wdp_racing]

Another person made it past the 20 min mark!! WoW! Much appreciated! Interesting!! And is the version that you mention above the first or second iteration of the tire. Because if it was the first i would really like to hear how the v2 version compares to the A052 (which is also a great tire). Thank you for watching!

[@slowfrs]

@@wdp_racing Version 1 of the CRS tires. Unfortunately, a lot of drivers I know have moved onto other tires including the RE71RS, RT660, AD09 for their increased longevity and availability at local shops.

[@coach_rollbay]

Very informative and enjoyable video as always... As I have already driven both the Cup 2 and CR-S in the 991 GT3 RS , I couldn't agree more with your final verdict!!

[@wdp_racing]

Thank you for your comment! Glad to see that opinions match our feeling and data!

[@jaystuart1990]

Very good video! Subjective and objective data with good transparent detail! I think im going to try the crs next!

[@wdp_racing]

Another one that endured the whole 31 mins? 😬 Glad to read it was useful and I hope you will be pleasantly surprised by the tire! What are you fitting them to?

[@korzry]

Great video. Thanks for sharing your insights and data. I will definitely be trying the CRS next time.

[@wdp_racing]

Thank you for commenting and glad to see that you found the video of use. Trying the CRS will definitely Italy surprise you in a good way. At least it did for us! 🔥

[@markdavis911time]

Thank you for this very interesting video. Great work and useful evaluation of both tyres 👍

[@wdp_racing]

Thank you for taking the time to watch and comment! Also glad to see that you found it somewhat useful! We definitely want to try and do some more of these comparisons for different tires out there, so stay tuned! :)

[@markdavis911time]

@@wdp_racing I drive a Porsche 991.1 C4S and was surprised by its potential to understeer, during tight corners on track. Would be interested to know whether increasing the front tyre width might help? Currently running 245/35 R20 on 9J / 305/30 R20 on 11.5J rear but have wondered about 265/30 R20 front.

[@MrSuliatkdc]

perfect test 👍👍 thank you very much. BTW did you try testing on 991.1 GT3RS and what camper figures do you recommend please.

[@wdp_racing]

@@MrSuliatkdc Hello and glad you found the video useful! As we do not own a 991.1 GT3RS for the time being we can’t say we have tested it ourselves. But @k.zannos has plenty of experience with all kinds of Porsche platforms as a performance driving coach and he can confirm same findings as on the current video. As for values, due to the McPherson layout at the front, all generations up to the 992 love camber. So if we are talking about track use and optimising grip and tire usage, then you can be looking at even values of 3.4 at the front and something more like 2.8 at the back. Hope this helps!

[@To.red.supercars]

Great video. I'd love to see a comparison with the Goodyear Supersport R, which is another OE tire coming on the GT3 and GT3RS

[@wdp_racing]

Ask and (maybe) you shall receive! :D We actually have a set of Supersport R mounted on our GT3RS spare set and we could be doing a comparison as soon as the OEM sizes become available. As budget is not unlimited and these tests cost quite a lot to do, i think we will waiting a little bit lto see what kind of request you guys are asking the most and will try to get it done! The GY is definitely one of the contenders!

[@wdp_racing]

And thanks for watching!

[@l-conceptracing406]

So maybe the Bridgestone Potenza Race could be another contender… who knows… Thank you guys

[@nick8me]

Plus 1 for Goodyear R except we already know it will be slower. It does however stay way more consistent and lasts longer than cup2 so it’s overall the best value tire. Hope your test can incorporate those elements. Bridgestone Race is next level amazing but only fits 991 GT3 and a few other cars with smaller wheels.

[@wdp_racing]

@@nick8me Very well noted! It seems that the GY-R has a lot of interest!

[@nankangtyreuk6436]

Well, We've just watched this here in the UK. What a fantastic video! Clear and concise with data to match. Are you ok for us to share this on our social media?

[@wdp_racing]

Thanks for watching and for the feedback! Seems like Nankang has managed to make a great tire. We are looking forward in putting more kms on the tire and see how it performs until the end of its cycle! Sharing the video is absolutely fine with us! That was the purpose of doing it. Sharing information.

Really precise ! Loved it. Would be nice to compare it to the A052 in the wet.

[@wdp_racing]

Thank you for watching!! Comment noted! For the moment we really feel we want to do some more testing on the dry and maybe as winter is closing in.. we get to do some wet testing as well!

[@dvas2686]

Good vid, I like all of the tire reading and data analysis at the end. But wish you had been able to complete some tracks without traffic. And, for us in the states, a typical track day session lasts 15 - 25 minutes, or roughly 30 miles / 48 km, so a tire that can be consistent for that long would usually suffice.

[@wdp_racing]

Thanks for watching and for the feedback! I would say also here (in Europe) we do the same. I mean thinkin about it logically, you shouldn't really be out there wasting resources when you feel that the tires have started giving up and dropping in performance. The only reason why we set out to do those 10 laps was because we wanted to push both tires a little bit to their limit and see how they perform and how they wear beyond that. Otherwise we also would have stopped around the same mark. No real point going any further except if you are racing.

[@997GT3R]

Thx for the great Review. Can you pls share the hot pressures for each tires

[@wdp_racing]

Thank you for watching and commenting! CUP2: F:2.3 - R:2.5 CRS: F: 1.9 - R: 2.0

[@AI-Records24]

Great video lads, I haven’t had chance to try CRS yet. I run AO at the minute on my track car and PS4S bmw spec on my road car, then PS4 on the family car. I have tried AR1 before the AOs, and in my opinion they are a brilliant tyre. What do I prefer? Remains to be seen!

[@wdp_racing]

Thank for taking the time to watch and comment! Great to read about your personal experience and also interested to hear what you have to say if you drive the CR-S over the AR-1! How do the Yokohamas feel compared to the AR-1 and what is your track car?

[@gogolglaus]

There is the Cup 2 R if you want a hardcore track tire. The CR-S has no Porsche spec, right? I assume on the front the tire flank is too stiff?

[@wdp_racing]

Definitely the CUP2 R can achieve better performance. But this comes with a cost of high wear and a higher price tag. Like we hae said before it all boils down to the choice and the goal of the person driving. And thats why we would love to test them all and let you know with the most objective way possible what to expect from each tire!

[@FreestylerAlbert]

Constructive comment: PLEASE give exact numbers. You speak it was 2 bar on the CUP2, went up to 2,5 2,8 so this is not what they recommend. But you never mention in the video what is the recommended by the manufacturer. This was at least 3 times in the video, this and that is recommended by the manufacturer but you don't share the data WHAT was the recommended. Questions remained: What is the operating temperature of the CUP2? What is the operating temperature of the CR-S? (Same like th AR-1? 70-105C ? ) Here at least it was said 2 BAR hot is the target. But wasn't meantioned rear and fron too? identifcal? The tire heat map on the right : green is bellow 70? yellow is bellow 90? and red is over 100? Also you mention you need to change the camber to add more. Yes but also didn't menstion from what , not a single mention what is the current setup sadly :D Thank you and please take it as constructive comment.!

[@wdp_racing]

Hello Albert, thank you for watching and for your comment! We like people who are curious! Recommended tire pressures for the CUP2 on the 911 Porsche is 2.3F/2.5R. Operating temperature for the tires. Tried looking out for you for this information but couldn't find anything solid. That never really was our worry as it is not a deciding factor for purchasing any of these tires. Both of the tires, such as all the trackday tires are expected to be performing in varying countries, temperatures so the window of operation is quite wide in all cases. So much so that searching for something that can perform in lower or higher ranges would be looking for something really specialized. The color coding you are describing is exactly what you are describing in your text. Thsi is the coding our sensors are running. To our fault, the rear sensors were masked with tape over them (which is something we do to protect the lenses when the car is driving on the road) and that is why they are showing green all the time. This is also why we did not dive into temperature readings in this video. Last but not least, the alignment we were running on the car consists of -2.4F/2.0R camber. Hope this gets you covered for now and thanks again for watching the video.

Cup 2 R vs Goodyear Rs vs Trofeo rs

[@wdp_racing]

Ouf that’s a high bill!! 😂 Although we have something cool in the making which should be out soon! And it has some of the options mentioned above! Stay tuned! 🎉

[@TRZ0612]

Where do the CR-S V2 sit as far as sidewall stiffness to others? A052 is pretty soft (but not as soft as Cup 2), Yoko AD09's are really stiff with a 3rd ply high turn up belt, RE71RS from what I have heard of them, sit somewhere in between the A052's and the Cup 2's. The stiffer the sidewall, the less "springy" a tire is on the vertical axis and the more stable it feels in high speed sweepers and initial turn-in

[@wdp_racing]

First of all thank for taking the time to view the video and comment! Based on my personal experience i would rate them as below ( Stiffer --> Softer ) - CRS - AD09 - A052 - Cup 2 - No personal data for the RE71RS. I would never place it close to the Cup2N tire. The difference is vast.

[@TRZ0612]

@@wdp_racing Thanks for that. Interesting that the CR-S sidewalls are even stiffer than AD09’s. Can’t wait until stock sizes are available mid Sept here in NA. I’m on the list for the CR-S already. Looking forward to the extra grip they will provide over the AD09’s

[@4timus]

Super video, thank you! Couple of questions please: Do the Nankangs really run much wider than their actual size? How is the width compared to the Cup2? Also for the GT4 putting CRS on the back would you recommend 285/30 (as rear traction is not really a problem) or 305/30(maybe rubbing in compressions)? Thanks!

[@wdp_racing]

Thank you for taking in the pain of the 30 minutes and for being curious! In our GT4RS we are running AR-1 305/30 just because that engine can actually take advantage of the extra rubber but in the case of the GT4, and given how the AR-1 at least was a bit wider than the CUP2N, i wouldn't be afraid to try the 285 size. The difference we measure from the Cup 2N on the stock wheels of the GT3 are of 10mm at the front and 5mm at the rear. Wider for the CRS in contrary to the CUP2N. Hope this helps!

[@4timus]

No pain at all😂. Extremely helpful, keep up the great work!

[@rafaeldelrey9239]

How do you get those bars for tire temps?

[@brad7425]

Very good information in this video. Do you know which one faster on track, AR1 or CRS? I love cup 2 or even cup 2 R, because they are the OEM tyres for GT3/ RS. But now I should try CRS.

[@wdp_racing]

I don’t have an actual number to back up the feeling but the CRS sure feels more refined in the way it handles and also in the way to starts to wear. It definitely is worth trying and seeing where it sits for you. As I say in the video, it all boils down to what you are asking for from a tire and how you are going to use it. Thanks for watching 👌

[@CK-297]

I'm looking to change my tyres this week on my Megane 4 RS Trophy-R (I noticed one at the start of this video...is that yours?) I only drive my car on sunny weekends, hard, up mountain passes. Would you happily fit the CRS if you were in my shoes?

[@wdp_racing]

The Megane shown in the video is not ours but we have plenty of experience with the car and feel more than qualified to offer our opinion! The CRS - like many other R-rated tires out there - would be a great fit for the type of use you are describing for the Megane. It will transform the way the car feels, the way the front end supports the car and the way the rear end follows the lead of the front. Being in your place i would definitely try a set on. Hope this helps and thanks for watching.

[@CK-297]

@@wdp_racing Thank you very much for your reply and opinion. I will definitely buy a set and look forward to the results 👍🏻

[@fanaticdusty]

Are the CRS wider than the Cup2? How much wider? CRS more rubbing or scratching than the cup2?

[@wdp_racing]

Actual measurement that we got by hand with the tires fitted on OEM rims. Front Cup 2: 240mm Front CRS: 250mm Rear Cup 2: 310mm Rear CRS: 315mm Rubbing is not something we experienced even at the very high compression zone of Eau Rouge.

[@wdp_racing]

Fair guess but not true :) The stickering on the car might indicate such thing and yet these tires were not! We are supporters of the Nankang AR-1 and we have been using it for our fleet because of its great value for money and grip as we are also using the Michelin 4S on a spare set of rims during rainy days for its superior grip in the rain as well as heating up properties. Thus the stickering.

[@Jim-rm5vy]

Really complete and detailed video, Nankang seems to have a better longlife but the price is also over the PSCUP2 😢

[@wdp_racing]

That is a very good point and as said in the video i really feel that it boils down to budget and what is your personal goal. If longevity is more then you will be definitely be getting your extra money back from the less often tire changes and also the extra kilometers you put down before needing to change them. And on top of that you will be having better cornering performance. It is kind of the same with brake pad selection. We always choose and go for endurance compounds which costs more than twice the money of a normal sprint pad, but in the end you get all of the money back by simply doing less work on the car and driving more.

[@wdp_racing]

And thank you for watching!

[@kaganaydn2105]

Video started good, but turned 180 degrees towards the end. Instead of spending data analysis that much time, why not finding a track/day/trackday and compare the tires back to back with 2 perfect laps? This should take less time than doing this and will be more solid and robust. You may never know how prior corner effects the next one.. BTW CRS and Cup2 are not rivals..

[@wdp_racing]

Thank you for your input! The data part would happen anyway, as we love more objective ways of comparing things. We also do feel that it was long but it was necessary in order to showcase what we wanted. Doing another trackday, on another day means double the costs on everything and again potentially not being able to put in a clean lap. And definitely wouldn't take less time! You are very right on the variability that changing a line prior to another corner brings and that is why we tried to minimise this by taking as many clean passes we could throughout all of our different laps. The ideal would be to have clean laps! We couldn't agree more to this! And thanks for watching!
