A050 M seem to grip OK even when cold just an excuse to post a pic of the mighty 120Y at Mt Cotton yesterday But they are the grippiest tyre I've ever used.

I ran on the Hankooks Z221's for the first time recently in my new bus as they are the control tyre for AMCamps. These weren't the softs that the WTAC guys run. They were the normal compound. One int

Do a couple of quick heli's in the closest intersection and then park it back in the garage overnight.

DOT? We're not in America. These are DOT too:

NT01 have no load index rating on the sidewalls. They're not road legal in Australia. They're not CAMS approved either. They're not good for much at all really.

Are the nankangs road legal?

I reckon 265 vs 265 Nitto v nankang that they would be very similar speed, but also willing to bet the Nitto would be more consistent over the lifespan of the tyre and the nankang will fall off.

Yet you hold such a grudge.

Anyway I'm over it. Back to real data and no more speculations.

lol Silly me! I thought I had real data having used both tyres on the same car. I defer to your "I reckon" and "I bet" guesswork based on never even having seen one of these tyres...

no, but your post did - you asked me a question (yes the Nankangs are road legal btw), then told me I hold "such a grudge".

NT01 are consistent, that's true. But you can't lose what you never had :P

AR01 could drop off at least a second over their life and still be as good as brand new NT01s. The soft compound Hankook Z221s when they had totally given up the ghost and were sliding around all over the place were still faster than the NT01s, but it was time to chuck them out as absolute garbage.
What the Nankangs do over heat cycles remains to be seen. I've had tyres that heat cycle really well and ones that deteriorate very quickly after a handful of track days, but I certainly can't tell which would do what from just driving on them once, let alone just from their brand name.

FWIW, Nankang has technology licencing and technical support agreements with Yokohama... That's from Yokohama's website, not Nankang's - they don't mention it at all. Who knows how much of their technology is involved with the AR1, but it was one of the factors that encouraged me to take the gamble on these $209 semis! lol I wouldn't be so quick to write them off before trying them.

I'm keen, but they need a new name LOL

call them Yokakangs.. I will buy

Nankangs, no...

I nearly killed myself 10+ years ago on Nankangs NS-2.. now that I am older, wiser and have some form of cash flow I refuse to buy Nankangs.

Nt01 is only a intro semi which back before the rsrr was released they could be had for the same price.

This argument is silly.

I agree, because Nitto has beautiful women promoting the brand so it must be good.

lol this thread heated up ;) I've used NT01's which are a real semi slick and not bad but not up there with the best for racing in 2016. One thing with Harry's reports is that they are roughly comparative with the other tyres he has used so to dismiss them outright is just plain dumb. Then again he won't say what cold pressures are used so...........

Agree that testing with the same car and driver is the best evidence. Not sure why you think his cold pressure is a big deal, just play with it and see what works. Will be different on different cars anyway.

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)

What's wrong with the R888 (besides being the same compound as NT01)?

The replacement tyre R888R is street legal, it'll be interesting to see if the upcoming NT01 replacement will be too, and whether they'll again share the same compound.

Also the NT01 vs. RS-RR comparison seems a little odd, they're a different category tyre aren't they (100 treadwear semi vs. 140 treadwear street semi)?

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.

      Looking for someone with a R34 front bar

      Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂

      new 1.5 LSD issues/concerns

      By Dose Pipe Sutututu · Posted

      Is this a brand new LSD? if so, have you followed any break/bed in procedure for it? Usually involves heaps of figure 8 patterns, a fluid flush.
