I hear you. I was am still of the same thought.... But with the limited availability of the front size it's made me doubt how important that is. I know the RE050a are still available here (old tyre) but there are much better tyres out there I believe so I don't want to buy them again. The Pilot sport 4 only comes in 245/40/19 so there is no option for the front for that, not even a different alternative. The Pilot Sport 4S is not here yet (as it was when you bought the 4S for the front tyres, but supposedly here mid 2017 whenever that is) and I have tried a number of places... So overseas is the only option for them at the moment. I have asked tirerack for shipping costs but looking at 1000 usd + shipping for them. This brings me onto another topic... Will the Pilot Sport 4S conform to the Australian market when imported from the US? Luckily my tyres are still legal, just quite slippery in the cooler weather now they have warn down low. And thankfully the rear is the worst so the front still hang on OK.

To make things a little easier I have read the G37 guys/gals also run a 245/40/19 on the front with a 275/35/19 on the rear. Makes the rear about 0.5% smaller than stock and the front about 1.1% smaller. So not quite as close as the 265/35/19 (1.6% and 1.1%) but seems OK for rubbing and also difference between front to rear increase/decrease. So in stock sizes the front are 1% smaller than the rear, with the first combo front 245/40/19 and rear 265/35/19 are 1.57% smaller, with the 275/35/19 its 0.52 smaller%. Anything more than 3% supposedly could give problems with the abs or traction/ECS. This is opening up tyres again for the V36. Seems to be heavily discussed with the G37 guys, but not much here for the sizes.

Thanks for the input.. Very helpful. This was one of my fears, as while I do plan on a track day at Wakefield in the nearish future (no record breaking times in a stock manual V36 other than the whiteline sway bars) but my main focus was a grippy street tyre. I had read once about the ad08r liking heat, and I have driven on tyres that needed heat before, but I'm just heading into winter and 99% of their time (75% wear say) will be on a commute. I understand most performance tyres need some form of heat into them, just trying to work out whether they are worse than the Falken RT615 (or 215 I can't remember) I have had on a previous S15 or not. I have not read many posts about the Pilot Sport 4 (or 4S) needing heat on the road. I have read that the ad08r is a great tyre for track use that's still decent on the drive on the road.

OK. I'm leaning towards the PS4S if I can source them here in OEM sizes. Looks like they want 1k USD plus shipping from tirerack ouch. Have asked Tempe tyres if they can source them but doubtful anywhere in Oz at this stage by the looks of it. Next up is the AD08R in the 1.1 to 1.5 smaller diameter (front/rear). I have left this topic here as I thought as the difficulties are in the sizes and range available for the V36 OEM rims that it wouldn't only clutter up the other thread. Was hoping others may have chimed in specifically for the V36/G37 OEM 19 inch tyre options here in Oz. I'm not wanting the RE050A's again.

True ha ha. I sorta misunderstood what you wrote and didn't even realise there was a PS4S. Thought you meant PS4's and back when you looked you had to get them overseas but they existed... So I searched and still found that they can't be got here in anything but 245/40 in a 19. Anyway, think I'm just confusing myself. So in summary; The PS4 look great except no sizes other than rear (like you said) which means same front to rear. The PS4S are still not available here, but are available in both front and rear sizes (as you said). I like these, but looks like they need to be brought in from overseas. Seem to be great for every day and could be used on track. The RE003 look far less appealing after reading the stickied thread I somehow missed (too much reliance on the search function). The reviews showed them highly rated but mixed feelings here. The RS3 appear to not have anything suitable but the 245/40/19 for the rear which would mean I'd have the same front to rear which means 1% taller in the front only (not sure about rubbing on the front due to width either). The AD08r seem to have 245/40/19 for the front and 265/35 for the rear (1% smaller all round but OK). Need ot consider rubbing here as well. These seem to like warmth to get sticky so winter mornings might need some heat put into them first (I live south west sydney so the mornings are getting cooler). But good once warm and also decent on the track. The Nitto Invo's come in both sizes it appears. Haven't looked into them much but did consider them years ago for an S15 project before I grew up and bought the v36 instead

Can you send me the link to this tyre thread? I don't really see one other than the one in the suspension forum and that isn't overly detailed, nor answer anything related to v36 wheel sizes specifically. The Pilot Sport 4's are very limiting in size here in a 19. I can only find the 245/40/19 and thats it. So only the rears. I am now toying with the idea of not aiming for the specific tyre sizes as factory but to change the diameter by the same amount (preferably marginally taller so the speedo is closer to being right if anything). I'd like to go the 245/40 front and 265/35 rear, due to the 245/40 being readily available in most tyres but then the rear size is harder to find.. And not sure the 245 in the front will be OK with rubbing in a coupe. Best bet would be a 235/45 in front and a 255/40 in the rear. SLightly higher side walls but speedo will be fine. Not sure how common those sizes are either. I guess I have a bit of work ahead of me. Table to help me make tyre pairs/combo's. Differences are based on the OEM sizes. front diff rear diff 235/40 -2.2 255/35 -2.6 245/40 -1.1 265/35 -1.5 235/45 1.1 255/40 1.1 245/45 2.6 265/40 2.2

The governing thing for me at the moment is do I stick with the standard 225/45/19 on the front and the 245/40/19 on the rear. As the front might help decide what tyre I buy out of the list of 6 or so tyres now. PS4, add that to the list Hadouken mentioned as well then I guess. I also looked into the Nito's a while back as well. I'll move this to general tyre performance/choice to the tyre forum once I find it.

Thanks. Hmm how have I managed to miss the tyre thread? I searched this v35/v36 forum and didn't see it. TIme to back and search. Does it also tackle my questions about the OEM sizes? I am happy to go 1 to 2 percent higher in diameter all round if need be as the speedo is out anyway (just don't think I should go different variance front/rear. I'm leaning towards what Nissan thought should go on the rims if I can find a decent tyre in 225/45/19 hmm.

New shoes/tyres I know this has been asked many times but hoping for some current advice on new tyres for the V36. car: V36 Coupe SP Manual with the standard 19's I think these are rim specs but not certain. The tyres are the same thats for sure so pretty sure this is right. Front:Wheels: 19"x8.5". Cast aluminum. Made for Nissan/Infiniti by Enkei. Weight: 26.5 lbs. Bolt pattern 114.3 x 5 Offset +43Tires: Bridgestone Potenza RE050A 225/45/19 92W. UTQG 140AA, weight 27 lbs., tread depth 10/32"Rear: Wheels: 19"x9". Cast aluminum. Made for Nissan/Infiniti byEnkei. Weight: 27.5 lbs. Bolt pattern 114.3 x 5. Offset +45Tires: Bridgestone Potenza RE050A 245/40/19 94W. UTQG 140AA, weight 30 lbs., tread depth 10/32" Currently running Bridgstone RE050A's and they were OK except a little noisy. It's a bit hard to compare as they are the only tyres I've had on the V36 but it's inline with what I have read. Now the rears are closer to the wear markers and winter is kicking in (and thinking they are old...), the traction is not great any more and on some occasions terrible if the tyres are cold even in the dry. Cornering seems OK but any throttle and the car likes to over-steer. Fun but not ideal when not trying to with the misses in the car ha ha. I can now hit it in first gear with the clutch already out and chances are the rears will spin in the dry and in a straight line. I am looking at the Bridgstone RE003's on the standard 19's. Would I get away with 245/40/19 on the front, over the standard 225/45/19? The same on the rear, or a wider 275/35R19 on the rear? Doesn't appear the 225/45/19 is available in them. Or doI go the bridgestone S001's? The fronts are available in the s001's. Do I go wider anyway? Or stick to OEM sizes on the OEM rims? I was originally wondering about Toyo r888's and also a few other higher wearing tyres but thinking the RE003's are a good balance. Any other suggestions? I am not brand loyal other than considering two bridgestone tyres above. I hope to track it in the near future, but the car is mainly a daily so don't want to base it purely around track times. I'm prepared for some wear if it means decent grip however.

Whiteline here. Here's the thread

The installation was easy. The longest thing on the front sway bar was removing the bolts for the plastic tray. Which I decided to use a cordless drill and a 10mm socket at the end. The rear took a little to wiggle the sway bar out without undoing any of the exhaust. It was tight but got there eventually, almost like one of those mind games of twisting things. I took a shortcut on the rear and kept the standard links however, but thinking I may change to the whiteline adjustable ones as I am worried the stock ones could fatigue with the stiffer sway bar in. Or maybe just wait until the stock links break then change

Ok. So initial impressions with whiteline sway bars installed, soft in front and medium in rear. Cost me $450 and decided to install myself as the place I was booked into messed me around. Car sits flatter which I expected, but surprisingly more stable on small undulations/bumps in the road where I thought it would would give more feel/pull on the steering wheel. This I am not sure of, but it appears that there is less traction in the rear end round tight corners which I understand is likely with a firmer rear sway bar = less traction on cornering. But this is initial thoughts and it really may not be that much different as my potenza re050a tyres are fairly temperature dependent especially under acceleration. It definitely sits flatter however.

Ahh makes sense. No plans to lower my car at this stage. If I do change I will factor those bits on aswell though.

So I'm assuming you're saying the v36 likes more rear camber?

I hear you. Thanks for the suggestion.

It's a daily that will eventually hit the track for the odd weekend. Was planning a track s15 but decided to buy this as a great daily instead with the odd track day. But mostly daily. Yes I am in Sydney. I have it booked in for the sway bars (whiteline - see other thread) and full allignment at Blairs Tyres in Narellan. I have had great experience there previously on my S15. I went ot Pedders in Campbelltown and they offered great service (suspension sqeak unsolved because it was wet but they didn't charge me) but they quoted like 5 hour labour + full price for the sway bar... So decided to go where I knew. I'll give your suggestion some thought though as I know how much a bad alignment can change handling as I had this on the s15 with Bob Jane.

Ok. 370z appears soft front and medium rear. Assume this encourages over steer rather than under steer which I'd prefer.

I'm going to aim for nominal. I understand more negative should improve cornering (within limits) but wear tyres out. Caster will change how much it wants to drive straight or corner. At the moment it's too sensitive to turning, especially on high speed corners.

Wheel alignment I've searched and found some info but nothing overly comprehensive. I have attached the specs for alignment for a v36 coupe from the service manual of a G37 (assume they are the same). I've got an SP coupe but assume it doesn't matter if it's a sport or not. From my understanding caster is adjustable front and rear. Alignment same. But camber is only adjustable in the rear which is only minor adjustments. No camber adjustment in the front on stock suspension. Getting it done on the weekend (along with sway bars) so hoping this is all correct.

Ok. I decided to book it in at a place with the pedestal hoist and get the alignment, caster and camber all checked as well. Going to aim for the stiffness mentioned above as a syatywoamd see how it handles... Unless someone jumps in before Saturday. Now time to search this forum for people's opinion on alignment (i have the G37 service manual)

OK. Maybe I'll look at getting them done at a good tyre place I know and get the alignment, caster and camber checked at the same time.

I should add. I was going to get my squeaky suspension fixed/checked and decided let's hope this will fix it... If not, we'll it's a good excuse to upgrade as it does roll a little too much for my liking. Suspension squeaks more on hot days, going over speed bumps or even just going diagonally up a driveway gutter slowly.. So hoping I kill two birds with one stone.

Sway bars I just bought a bargain set of whiteline sway bars for the v36. Now tossing up whether to do it myself or hand it to a suspension place and get an alignment done at the same time. Now the questions (I haven't got under the car yet) - How hard is the front sway bar to change? No steering rack removal or anything like that that is there? - Believe the rear bar should be easy, but possible the mufflers might need unbolting to get the rear seat out. - Estimated 1 to 2 hours max for swap? - I plan on using the supplied front links to replace the factory ones. Good choice I assume. - Rear links remain factory I believe. - Suggested setup? I believe middle firmness for front and soft rear? Prefer firmer than stock. Car is a daily and prefer to not get to twitchy over bumps round corners. Will consider going harder for my track day I'll eventually do.

I'll offer $250 for the cruise control shipped to Sydney but assume you won't take that offer?

So more specific software like Nissan consult and the required hardware is needed to even read info from the ecu on a 09 v36 3.7l huh? So my generic elm327 and torque app won't work? Mine doesn't work and google search leads me to believe this but thought I'd check to make sure in this old thread.
