I needed a pair of wheels when I got my 265s all round too. I went with Koya CR Tek - cheap, strong, and proven on the race track.

18x9.5 was widest they have, but that's perfect for 265s anyway. Offsets are cut to your specs.

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.

lol you should probably say, or update your sig then :P (edit: make that profile, I can sort of see it in your sig now:blush:)

you are probably limited to 8" on the front of a 33 gtst unless you are putting larger guards on, and that means no larger than 245s.

as for brand I'd just ring the local motorsport suppliers and see what they have....I haven't bought slicks for years but I think they are worth considering for track only

I run a 9" R33 GTR wheel (+30) with 255 z221 on the front with no issues.  Guards have been rolled though.

more or less what i was thinking....

Might grab a set of the nankangs 265 all round. that way can rotate the tyres.

have to find a set of 18 9.5 +12 or 10.5s rims cheapish

I'm not sure if a 10.5" +12 wheel with 265s will fit on the front of an R33 GTST with some serious guard work?

I've been running 18x10 +12 with 265s up front.  Nothing too serious on guard work, an hour with tin snips & hammer, and screwed on some flares.  Works well, beats trying to roll a lip etc.

Used the Nankangs at Mt Cotton hillclimb on the weekend. They were great - work very well from cold. I've never felt a semi work so well in Turn 1 out there.  The sharpest steering response I've ever felt into T1, with not even a hint of understeer and probably the best traction I've ever had on the way out of T1. Actually, they've got excellent traction off all the slow turns out there. I'm very impressed with them. Had to be careful not to overheat them with the burnout - just a very small 2 second burnout to warm the rears was about all they wanted. Any more and they went a bit squishy.
Haven't seen the times from the last couple of runs yet, but runs 3 and 4 were 47.9s which is 4 tenths faster than the Nittos were there (without tyre softener). That's heaps of time at a ~48sec hillclimb, and I reckon I went faster on the last run. Just waiting on the results to be emailled out.

So Harry - at the price point where AR1 (and NT01) live - you're not seeing anything about the Nankangs that's a negative from a clubman motorsport perspective?  Bearing in mind that's about the level of most forum conversations and budget constraints for "average" enthusiasts.

Seems the AR1 on a heavier car, dry track, can do the job for hillclimb (nearly dead cold rubber) and sprints (~10 - 15 minute session so generating a bit of heat) pretty well, faster than the Nitto with more grip generally.  It will be interesting to see how they go for durability.

How do they feel for carcass rigidity, and progressive breakaway when they do slide?

I'm very interested to see what you think overall.  Accepting they're not likely to perform at A050 or Z221 level, these things have to be on a few people's lists when not chasing sheep stations.

They're in a totally different league to NT01s. No doubt whatsoever. There's no downsides to them. The guy who fitted them has been selling NT01s for years, said the Nankangs definitely have stronger sidewalls. They're good on the limit, and when you overstep it. No quirks or foibles at all - they just perform like a good semi slick should. They might not be quite up there with A050/Z221 mediums, but would be FAR closer in performance to those than the Nittos are to AR1s. I'm hoping they release a 295 or the back of the Soarer... Would be awesome for the hillclimb if they release a soft compound!

I've done 3 trackdays and one hillclimb so far, so it's early days to be talking about durability, but no concerns so far in wear or heat cycling.

      S1 rb25/s14 starting problem

      By Duncan · Posted

      Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      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.
