Got a set of ku36 a few weeks ago from local tyrepower shop in Albury.

Prices were as follows

235/45 -$200

255/40 -$285

245/45 -$245 no stock at the time

Hey Luke,

Thanks for the info. Good prices there, but after factoring in freight and fitting costs, its probably no real saving to buying them locally unfortunately. How do you find the Kumho's? Im thinking about getting a set for the road now anyway.

I have Kumho KU36 on my Supra because I track it fairly regularly and only have one set of rims. Good tyre for what they are, but they're not a semi slick. I use 245/40 and 275/35 * 18. I've done 2 Lakeside Sprints, 1 QR Sprint and probably 5000km of street driving since Sept last year.

On the road:

they're not loud, good in the wet, but tramline alot (I run a fairly agressive alignment too so its hard to say how much of that is caused by the tyre).

On the track:

- Only really good for about 3 laps before the rears go off. This is on my Supra remember, and my rears get a fair workout from my driving style... Might last a bit longer on an AWD car. I'm careful not to warm them up too much on the warm up lap as they work best just off cold. That's not to say they're better than a cold semi slick - they're not.

- They need alot of pressure like a street tyre. I run between 36 and 40psi cold. I found there was no point aiming for a target hot pressure because by the time they get hot, they're past their best. Better off aiming for a hot lap straight off the cuff with these tyres. Mine generaly come on the 1st or 2nd flying lap. byt he end of the 3rd lap you have to start being a bit more careful with the right foot.

I'm really happy with them on the Supra. If you only had one set of rims and wanted a jack-of-all-trades tyre,I'd recommend them. Or if you just want them as a really good street tyre and aren't really concerned about wear, then yeah go for it.

Thanks for the info Harry.

I just talked to Alan at Z Car Workshop here in Briz and i can get the following prices for Silverstone Tyres

FTZRR in 235/40 (largest in 17) for $375

s585 for slightly less than $375 (no exact price)

Am going to go and have a chat to him tomorrow hopefully and see what they are like, as i havent heard or read much about them.

Try Track side tyres in melbourne. Craig is the man to deal with. 18 months ago we could get RE55's landed in townsville for 420 each for 255 17s. Very helpfull and if i was not getting toyo 888s cheap through my friends shop I'd use him agian for sure. Obviously with the exchange rate they won't be anywhere near that now but his service was outstanding.

I have only run them at a winton fun day so far, sprints start again in a few weeks.

Like Harry said tramlining can be a problem, but overall i'm really happy with them.

Harry how have you found the tyre wear so far?

Tony,,,I really don't know much about which tyre you should use,,,but what I will tell you is very simple.

If you want to go fast at hillclimbing you have to use the softest tyre you can find. Grip on cold tyres is what it's all about.

It's no secret that all the libre/sports sedans run avon slicks,,,why,,,because there's no way you are going to get heat in the tyres,,,so the only other way to get grip is a softy.

If I was using a Skyline for cllimbing and had a spare set of wheels I would buy a durometer and start testing tyre hardness.

The only problem is they will end up being hillclimb tyres only.

Neil.

hi, there :happy:

1) what does tramline mean?

2) i have used Firenza Sumitomo before and they were fairly loud. How's road noise on the KU 36 compared to this?

3) does KU36 have some sort of "rim protection"?

thanks

I'd recommend A050's - softs are ok for just hillclimbs on road going R32 - too soft for supersprints - we find mediums have done the job on both R32 & R33 at all NSW, Aussie and time attack events.

Tow out on the front, bitta tow in on the back around 28psi cold.

Enjoy

id also recommened bridgestone re070 as a 22545r17 has a speed rating of w=270k which are a good tyre with the write alignment

They do not even compare to a proper semi like the AO50

      Crank/No Start - R32 GTR Chassis with R34 RB26

      By 89GTR_VA · Posted

      Apologies for the long post, but needed somewhere to lay out the entire timeline of events and actions taken:   I've got an 89 GTR with a R34 RB in it. It's been running great all year, driven probably 500KM in the last month. It's not my daily driver, just a weekend fun car.    Build info: R34 RB26 - HKS 2.7 stroker kit, HKS adjustable cam gears, HKS turbo upgrades, Trust intercooler, R34 factory DENSO 440cc injectors, JUN chipped/tuned R32 ECU. All of this work was performed in Japan back in 2019.    Thursday 10/2/25 - It's a nice day and decided I'll drive it to work, I start it up in the garage and I notice it took a few extra cranks and sounded a bit funny. I figure maybe it was just because it was a pretty chilly morning. I pull it out into the driveway to warm up a bit before leaving. As I leave the driveway, it feels very off and sounds like a misfire. I pull it back in the garage to deal with after work and take the daily to work. I was able to diagnose it as a cylinder 5 misfire with the old spark plug test (unplugging each plug until a sound change with the engine running). I take off the whole ignition system, ignitor, plugs, spark. *Important note, it is still on the R32 ignition system with the separate ignitor system. I test each system with a multi-meter and nothing presents as a smoking gun. I put it all back together and it starts up no issue. I go ahead and order the PRP R35 ignition conversion kit. It should arrive today (10/13/25)   Friday 10/3/25 - Another nice day, car starts up great and drives great all day. Very pleased that everything seems to be OK   Sunday 10/5/25 - Decided I'll take it to play some golf, load up and drive to the course about 25 minutes away. Drives wonderful the whole way there, I pull in the parking lot and the engine completely comes to a stop. I do not recall if it sputtered at all, but just remember all of the sudden the engine was off. I roll it into a parking spot, try to crank it back on and nothing.  It'll crank and crank and not even try to start. End up getting it towed back to my house and push it up into the garage.    Items I have checked: Fuel in the tank Fuel Pump relay Fuel pump fuse  Spark Plugs & gap Coil packs Ignitor    I know the cylinders are getting fuel as the plugs smell like fuel after a start attempt. I tried spraying starter fluid into the manifold and cranking and not even a sputter.    I decided to do the live CAS test (removing the the CAS, ignition on and spinning the CAS stalk to see if the injectors pulse and spark is active). All of the injectors were pulsing and I have spark at the plug. The half-moon end of the CAS did seem very loose, I'm not sure how much play is supposed to be there, but it was more than I expected. There was no in/out play of the shaft, just the tip end that is pinned on had quite a bit of play.    CAS Play video   When I put the CAS back in, I stupidly did not re-time the engine. I know I need to do that tonight, however, I do not think it will start given it seemingly was not the issue. My plan is to do the PRP R35 coil kit and retime the engine at the same time.    I plan on ordering the Haltech Nexus Plug-in ECU once they are available again, but ideally would like to get this sorted before firing the parts cannon at it and potentially adding more variables.    Anything glaring that I am missing here, I'm a bit at a loss?

      Get it on a dyno. Get something logging Consult. Run it up and find out what is causing it.

      Freddy Plenum vs Genuine options RB25

      By BuiltNotBought · Posted

      Looking for a plenum for rb25 de+t neo  Not looking to push much power maybe 300kw at the wheels, is there much difference in flow for Freddy “Greddy style” compared to original Greddy or options like Proflow or Otaku garage?    I won’t be porting the de Neo head for now as I think it’ll be fine 280-300rwkw but appreciate the help and any experiences anyone has between them and any advice. Thanks  Looking at this plenum for now below
