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

On the road:

1) follows the contours in the road

3) yeah, pretty sure they did

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

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
