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.

      Quieter performance exhausts (or muffler add-on options)

      Nope.    Grab a varex and turn it down as you get close to home, win win?

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
