This sounds like one of those brain teasers

So turboadam are you saying a single point on a larger circle wil still take the same time to travel a full rotation than a smaller circle?

Common sense would assume the larger circle takes longer to rotate

Your rim has a smaller circumference to your tyre, but of course they both take the same time to complete one rotation otherwise your tyre would be spinning on the rim. The cap in the center of your rim also takes the same time for one rotation. The speed is the variable as the circumference increases.

EDIT: I have not received anything offering suspension updates for an MY11 to this new asymmetric design.

my brochure for my 2010 says $4990 for the brake upgrade and $13xxx for the brakes + suspension

nissan must have changed the calipers 2009 to 2010

the extra 10mm on the 2011 discs comes from wider hats and then a different bracket bw the caliper and upright to push the caliper out 5mm, otherwise us 2010 owners wouldnt be able to re-use our existing calipers + pads in this kit

so the extra braking performance 2010 vs 2011 isnt really from increased surface area of the disc as one would initially think, but rather from the increased cooling effect by taking a longer cycle for the disc to travel one full rotation under the pad

when im due for front discs, ill just order the new caliper bracket and larger discs as 2011 spare part like i did upgrading my M3 brakes to the larger CSL discs

I'm confused now as to what the differences are between the 09 and 10 brakes for the $5K difference in the conversion..... And if the main change between the 10 and 11 brakes is just a caliper spacer then what do you change on the 09 to go to 11?. Calipers, pads and spacer? Can't imagine that if they're charging $5K for just the spacer that a caliper and pad change will add "only" another $5K. At the drive day Mizuno told me that a spacer was all that was required but I don't recall that I had mentioned it was from an 09 to an 11. He would probably have assumed a 10 to an 11. What's interesting is that when I bought my 09 I was told that a complete brake pad and rotor change would cost $20K for front and rear brakes, it appears now that if you wanted to go down the OEM path it will cost you no extra to convert to the MY11 brakes than what it would have cost to just re-rotor and pad your 09 back to original brakes!

And the increased cooling is primarily due to the increased surface area and (thermal) mass of the rotor. There is increased braking force for the same amount of brake pressure because of extra leverage due to the centre of friction being further away from the rotating axis but this does not improve temperature performance because the same energy is being absorbed by the brakes anyway you cut it. You are actually correct in a way about the "time" aspect even though you didn't state it clearly because if the pad length is the same yet the rotor is increased in circumference the size of the angular arc the pad covers is actually reduced therefore any point on the swept part of rotor surface actually spends a greater percentage of the rotation period time exposed to the air and less time under the pad undergoing friction and warming up thus improving cooling efficiency. It's effectively a change in the duty cycle. It's not hard to visualise if you just exaggerate things up to bike tyre size etc for it to make more sense.

09 upgrade includes new calipers

10 upgrade does not

i did a similar upgrade on my m3 when i was due for new front discs. i went with the larger csl front discs and they came with a different bracket bw the upright and caliper - caliper and pad are identical

i doubt the change in r35 caliper is a mounting issue. id assume its some internal change they made to the caliper itself, and in "upgrading" nissan figure you're better off with the newer improved caliper - remember there is a visual difference bw the 09 and 10 caliper in the lettering on the face

doubtful

the rear seat delete means it'd have to be classified as a 2 seater - which means Nissan Aus would need to ADR it again ?

the bigger issue though is the Aus rrp - Nissan Aus in the 2011 model are now bringing in the base model Japanese GTR (all black seats and grey roof lining) to keep the currency exchange price rises as low as possible for the end consumer

this track pack would be pushing mid 2s easy

do you think we'll get it?

Some people are working very hard to make it happen, there is a good chance we will see it in Australia!

    • looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drive beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
    • Join SAU NSW for a flame-grilled feed & flame-spitting cruise!

    • Yeah good luck out there! Will be good to see a mighty GTST going harder than the GTRs
    • i will be there 😁
    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
