There was a BMI test a while ago, where they shod the MX-5s Mazda uses for their annual endurance race with different S-Comps. It should be on Youtube somewhere.

I think that the Z1s won, just beating the RE11s. There's still a lot of variables (like driver skill, and the condition of the car they were on, and the car itself) but they all came out reasonably close.

You are talking about endurance racing. If the Z1's outperform in an endurance race then they will probably do well in short track events but probably not the best.

What you need to ask yourself is what is the car being used for?

The Dunlops, and Bridgestones are stickier tyres than the federals and kumhos for sure but put them into a long term race environment and they will fall short.

Each tyre is built for a purpose, buy your tyres for what you intend to use the car for

from what i've heard the RE-11's are amazing, but as always they will be bloody expensive, and doubt they will be sold in aus. the Z1 star specs are a good jump from the KU36's without going too ridiculous with the $$

Tyre Power hawthorn(5mins from me) has them in stock.... they are also a rays dealer haha.

I guess I wasn't 100% clear. At least you didn't jump down my throat because of that misunderstanding, start a shit fight, and then later "play" dumb when its pointed out that you're the one that went off half cock for no good reason.

My meaning was that they borrowed the cars Mazda Japan uses in the endurance race for their test and fitted the various tyres to them. They didn't compete in Mazda's actual endurance race with a variety of tyres.

They only did about a half a dozen laps, as per the standard format BMI uses for their "races" in their videos.

yeh there are variables, but the fact that they can be shown to be competitive with the RE-11 yet cost nowhere near the same, according to tirerack, for 235/45's, Z1's are 5/8 the price of the RE-11's

cool, they didnt bring the RE-01R here so it's promising that there is a market for high end tyres here, hopefully it's not just them importing privately, and that bridgestone Aus is actually supplying them here.

cool, they didnt bring the RE-01R here

They did near the end of the tyres' life (maybe even after they were discontinued, it wouldn't surprise me if they used Australia as a dumping ground for old stock).

I'm pretty sure I saw them in Stuckey's web site earlier this year (or was it last year?) and Bridgestone Australia still has them on their web site.

Thanks for clearing up the endurance thing. My post still stands though. Tyres are built for purpose so it's still important to know how they will perform in different events.

I have no idea what you are talking about in the first part. I've got nothing to do with previous posts from other people. Keeping in mind, also, that it's in the past and I was sure I clarified everything for everyone so there shouldn't be any need for anyone to bring it up again. Or at least not to me.

hey guys, just wanted you all to know that we have the last and only 6 x 235/40/18 KU36's in Australia.

I would really love to set up something here so you all can know what we have and when we have something to offer you specificly.

PLEASE one of the mods or admins help us out.

so how are you still legally selling these? did you buy them from kumhos or are these the side imported stock you brought in and were supposed to forfeit to kumhos?

im just curious that is all

btw there are more ku36's in the country... just to let you know

Hi thanks for the question

We ONLY deal with Kumho Australia when it comes to Kumho.

All tyres we get are only from authorized Australian distributors, we do not believe in unauthorized parallel importing stock.

There are more KU36's but that size we bought the last of Kumho Australia's stock.

Well picked up a set of KU36 yesterday for the GTR.

Will probably go on the car this weekend, and will hopefully do Oran Park at the end of this month, will let everyone know how they go.

I had Michelin Pilot Sports II on my old V35, which to date is the best street tyre i have ever driven on. Gotta say that the rubber on the KU36's feels very similar to the touch but obvioulsy is more "semi" orientated in the tread pattern.

If they perform like the PS II's i'll be a very happy man!!

ah ok then, so u didnt have to forfeit your stock??

kumho must have been lying then

notes:

federal when new have good rear lateral grip, little bit of movement on turn in and mid corner but nothing major. as the tyres wore this reduced and

the car started to push. tyres were rotated very often.

federal had great grip on the front in breaking and turn in, bust lost a little and generally pushed in the corner as they wore. as the tyre wore they

started to squeal heaps.

as the tyres wore they lost some feeling the in rear and while sliding would bite hard wen you didnt expect.

in the rain...totally awsome. grip under breaking, mid corner. not as much while on the gas though.

the tyres would last 3-4 hot laps, then start to side around a little. they are down below the markers now.

kumho, ive only run once at winton short.

it was fun...the ass was out all the time.

um, lateral cornering grip was less than the federal. braking was great, better than the worn federals. but on turn in the rear was walking all over

the place, was a nice change from the understear of the worn federals.

no understear to speak of, the front didnt push at all. the federals would vibrate like crazy while pushing, non of that from the kumho.

the kumho heat up real quick and fade off real quick. i could really feel em moving around compared to the federal ( maybe due to the tyre

pattern on the kumho, the federal is more like a yoko pattern).

this was more of a fun day than the CSA day. and i had been in understear land for a long time with the federals, so sliding around the corners

was too much fun.

more updates to come on the kumho's. but for performance vs cost, they look to be just a little ahead of the federal atm. the wear will be a big

comparison...

just changed to a set of ku36.

<cut>

What tyre pressure did you end up running?

I've read somewhere here that people are running 38-40 psi (hot) in the ku36's but not sure of the exact size of the tyre they were referring to...what are you running?

I run 38-40ish in mine. 235/45/17

I found they got better after a few decent drives.

Would be interested in a follow up after another track day or two John?

ya will keep this updated. this was there first run, so they would be a little 'waxy' i think.

i ran the federals at 38hot, same with the kumho. trying to keep the sidewall up around the corners.

ah bugger, know i missed something.

same on the federals and kumho.

front

height = way too low, would be 20mm lower then the 350mm at least, but want the camber

toe = 1-2mm out

camber = -2 deg ( the most i can get from pedders bush, would love to run more )

castor = unknown

rear

height = way too low, would be 20mm lower then the 350mm at least, have to keep the balance good with the front

toe = level

camber = -1.5 deg

    • Yea that’s why I said ima test them with multimeter and see the reads.
    • Only at idle. Isn’t a problem when rev it seems.
    • @Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?  
    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
