Those Nankangs look pretty good, unfortunately their 17's are not wide enough for mine http://nankangtyres.com.au/tyre/ar-1/

Have to say that my present Hoosiers are doing well, they are wearing very evenly across the tread with the shoulders holding up nicely, better than any other tyre I've tried. The other thing with Hoosiers is their sizing, plenty of 17" choice in 40 series which keeps the width up and the diameter down to help clear the guards. EG the 245/40 Hoosier is 622mm dia, 235/45 Hankook Z221 is 644, the difference allows me to use the wider 245's on the front, comparable Hoosier rears would be 275/40 only 648 dia.

I'm talking sprints where there is time to warm the tyres up, not time attack.

The Nankangs are brand new. I'm sure there'll be more sizes to come.

Of course you're not talking time attack when you mention Hoosier. Time attack have to use semis. Hoosiers aren't semis, they're 2 groove 'cheater slicks'. The latest ones aren't even 2 groovers, just a few broken dashes. Not semis by any stretch of the imagination.

The Nankangs could turn out to be good going on the Hankook success story. Price them cheaply to get them out there and let word of mouth do the rest then when they get popular stick the price up.

Tried them yet Harry? C'mon, get a move on.

  • 4 weeks later...

Tried the Nankangs out last week. Ran a best of 60.3 but that was not really representative of their potential - the admin people listed me as entering a Toyota Starlet instead of the Soarer that has been in their database for years, so I got put in a slow group with cars running over 15sec per lap slower!!! That's alot on a 60sec lap. I lapped that car twice in one session... As a result, I was only getting one or two clean laps each session to set a time.

Comparison to other tyres I've used - no car changes:

235 Hankook Z221 soft C70 compound 59.8

265 Nankang AR1 60.3

245 Nitto NT01 61.3

The rear doesn't stay quite as attached as the Hankooks did on the fast turn onto the front straight. Mid corner to exit they start letting go just slightly. Other than that they feel good. They should be a bit closer to the Hankook softs than those times were, but I don't think they're quite a match for them. That's still an awesome result for a tyre that's $209 per corner, compared to arguably the fastest tyre available!

Wear was very good. The only question mark over them is a strange circumferential line that's appeared around the center of each tyre - it's not quite straight. I don't know what it is. It runs the wrong way to be a tread splice. It's not from contact with the body as it's on all 4 tyres, and there's nothing to hit in the rear wheel wells. there's definite contact being made on the body in the front right - you can hear it in the left hander "Hungry" corner.

I wonder how the NT01 in the same size would square up to the Nangers.

From what I'm seeing they perform well for you, but the adult in me is telling me to never buy Nankangs again because I'm not 18 anymore.

Pretty keen to try the nankang ar1s to be honest quite cheap.Might give them ago next round of tyres im only on kenda kr20a and nakang ns20r at the moment so would expect large improvement

I'd never buy NT01s again! Better off buying RSRs.

That's a strange result for RSR v NT01... Normally not that far off the pace of NT01, which is pretty god for a non R comp, alot cheaper, road legal etc

First I've heard of RSR delaminating too. Tread splice opening yeah, but delaminating?

Edited by hrd-hr30

When I reported it to federal they considered it delaminating. We are probably talking about the same thing here.

I don't think it's strange at all. Rsr lasted maybe 2/3 hot laps and then greased over, Nt01 I could go harder and get about 5 hot laps before they overheated.

But nt01 is still only a introductory semi whereas rsr is very much a street tyre.

Why would you never buy nt01 again?

1. They're the slowest semi money can buy.

2. They're not road legal so you can't even legally drive to the track on them which is a PITA.

3. They're not CAMS approved for production car classes.

You're better of doing very similar times on street tyres, or buying literally any other semi (other than R888 :P)

    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
