OK-quick run down:Near standard R32 GTR,uprated suspension,NOT a "daily driver",with 235 x 45 x 17"s.I'm after suggestions for a good trackday tyre.It's only gotta be road legal and not shred itself by 1,000 km's....Falken Azenis seem to keep popping up in discussion.I'm open to suggestion,except for cheap s**t that wont perform...Whadda you all think?

I used to run the Azenis on one of the new Mini Cooper S's, and were looking to do the same with the GTR. Was talked into using the Toyo Proxes RA1's. These are unreal, some of the best tyres (on track) I have used. I haven't run dunlop R's yet (due to the cost) but these are litterly s**t to a blanket. Slightly more expensive than the Azenis, but seem to be a slightly softer compound and extremely good holding tyre. I think they will probably wear fairly fast, but worth it.

Awesome :D

RA 1s are a treadwear of 40 so dont expect too many kays:)

Dunlop RE55s are cheaper than proxes or azenis here in SA, $350 for 235/45/17 fitted - they stick well. They also have a very stiff sidewall which isnt a bad thing. Interestingly the 235s I have are slightly wider than my 8" rim, but the 255s (RE540s) I have on the rear are exactly the same size as my 9" rim. Next time I will be going 235 rear.

I am prettys sure the RE55s are used as a control tyre in targa tas too.

Bridgestone make the re55s they are great, I had the wet compound ones which did not last but apparently thye have a harder compound too. We get club discounts on them from Gordon Levin in sydney. These are the stickiest tyres I've driven on.

Next best are re540 bridgestones or dunlop formula r (DJ01). I haven't tried the Dz02J Dunlops yet but apparently they are great (our targa car ran these)

Other options are pirelli p zero corsa or michelin pilot sport cup if you are made of money.

the Falken rt215s I haven't tried yet, but falken also make these babies so I'd be very surprised if the rt215s are as good as the other r tyres here.

Tempe tyres have these for $200 ea in 245/45/17 perfect for a gtr

Anyway, that was a long rambling post.....any of those tyres will be an amazing step up from road tyres. They are noisey, average when cold, wear out quickly and tramline. But the grip is just from another world :D

Hi Duncan you left out Yokohama's, we use A032R's. Similar pricing to the Dunlops and Bridgestones, but they have slightly more tread pattern so you can use them in wet or dry. Gordie sells them too.

mmm....what do you think of the yokos? I found them a little less grippy than the D01Js and re55s but costed a little more :rofl: Although we did put down one spectacular .47 lap of Oran Park in a standard n1 gtr when they were brand new :rant:, every other lap was about 2 sec slower!

I know we have to use them in combined touring and improved production but I think there are better ones for less money....

Yep Duncan, spot on, the A032's are not quite as fast. Their advantage is they are useable in all conditons, the RE540's and D98's are only OK in the dry. So it really costs three times as much to run them as you have to have a set of wet tyres on rims as well. Not that wet is much of an issue in Sydney the last 12 months, although it peeed down at Sandown and Philip Island. :boohoo:

The bottom line for me is the total cost of them is the same as running full slicks that last longer and are much faster. So although, not perfect, the Yoko's are the best compromise for the limited budget. :uh-huh:

The Yokos A032s are more expensive then the newer A048s, despite ppl giving feedback that the A048s are a better tyre, i suppose the fact that A032s are the control tyre in certain classes means that they can charge what they want as ppl have to use them if they want to race.

When my current D01Js die ill try the A048s, they are $15 a corner cheaper then the Dunlops, and have already tried the Bridgestones so its time to try the Yokos.

I like the D01Js, very progressive tyre and pretty good grip levels. they lasted longer than i expected too, considering my frequent trackday usage.

I'm using the Falken Azenis RT215 now. It has a semi-slick type pattern, but the RT215 is a street compound tyre, not 'R' rubber. Not bad on track in the first 3 laps, but pretty hopeless after that as it overheats. Cornering performance pretty good for a street tyre as the tread has broad blocks. Good compromise for day to day and occasional trackday, but in my own experience, i'd say just go straight for 'R' rubber if your car won't see much street use and you don't want to buy another set of rims + tyres for trackdays & semi-slicks/slicks.

    • Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?
    • This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?
    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
