What about Hankook Z221's, not the two groove ones. Only available in 17 and 18" but three compounds listed. For sprints I'd be tempted to try the softs.

Neil used them on the weekend at Bathurst and found they worked better than the Avon softs (that cost $200ea more). There's a reason they were banned from superlap

I thought Neil's Avon's were supposed to be the best thing since sliced bread with their special break in process.

If Neil is happy with the Hankook offering compared to the Avon's then they would be a great tyre for the money considering that they are hundreds of dollars cheaper each.

Go back to page 18 and read my post about them. Cliffs: Great when new, but the soft compound only last a handful of track days. Admittedly, I am hard on tyres, and the car is no featherweight...

If yours were softs then on your heavyweight and in hot weather that's asking a bit much don't you think Harry? I was thinking mediums for mine which is several 100kg lighter, something like 255 rear, 235 front tyres.

Richard: "For sprints I'd be tempted to try the softs"

Harry: softs don't last long

Richard: "softs were asking a bit much don't you think Harry... I was thinking mediums..."

Harry: :/ uh, glad I could help?

lol Yes Harry, instead of waffing around I should have come right out with it and said that the Hankook softs on your unsophisticated heavyweight very likely overheated and so were cactus from then on which was hardly the tyres fault. For me, being tempted to use softs is a bit different to thinking mediums which obviously is the safer option.

The hottest conditions I used them in was at Morgan Park at about 34degrees ambient. They showed no signs of overheating on the day - grip never dropped off like it would if they got too hot, and they still went well at a hillclimb and Phillip Island after that, so I don't think "they overheated and were cactus from then on".

There is no chance the hillclimb overheated them. It was nice and cool at Phillip Island and they were great down there too. Not only did grip not drop off in any session as it would if they got too hot, but I did my best lap on the last lap of the day. Next time I used them they were instantly horrible and got worse with each lap. They just lived their life-span of heat cycles if you ask me.

lol at someone running pogo stick and horrible multi-link rear suspension calling the Soarer's double wishbones unsophisticated!

Double wishbone suspension eh, like the old Holdens used to have up front. You are on a winner there Harry :no:

Anyway tyres. MP, depending on which circuit, can be a bit hard on tyres, all those sharp corners. And I have no idea if overheated tyres go off straight away or just can have their life shortened. Must check that out.

Semi related (pun) to this thread – what would you guys recommend running for a hill climb?

I've signed up for the Haunted Hills intro next month and have the following options:

  • Street rims: Kumho KU36 (UTQC 180)
  • Track rims: Toyo R888R (UTQC 100)

I'm guessing it might be hard to get enough heat into the Toyos to be effective on short runs...?

  • 5 weeks later...

As an experienced hillclimber, the semi (even the R888) will always be better than the KU36.

Thanks for the tip Harry, exactly what I did.

I'm really liking the R888R, even in my skinny 225/45ZR17 square setup. Very communicative and plenty of warning before they let go, in a progressive way.

I'm new to semis so can only compare to street tyres, but still definitely recommended.

yep, that's where I found them. My set arrived today. 265/35 R18 for the Soarer, so it will be a direct comparison vs:

245/40 Nitto NT01 - 1:01.3 Lakeside

235/40 Hankook Z221 - 0:59.8 Lakeside

    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.
