When talking with some of the motor sports engineers at Kumho, they were on the same way of thinking and actually gave me percentages that I had forgotten exactly, but they compared a 265 and a 275 contact patch increase versus the decrease in sidewall stiffness and actually recommended the 265.
-Also the stretched sidewall allows for a better taper to clear the inner fender well for less of a chance of rubbing.

Other examples that I have found in the 2 racing series are:
NISMO R1 with 10.5 rear and 265/35/18.
Autech Tsukada with 9.5 +15 and 9.5 +15 with 225/40/17.
Power House Amuser with 10.5 +22 and +18 with 265/35/18
Yashio Factory with 10 +15 all around with 265/35/18
Sunline racing with x10.5 +16 all around with 265/35/18

There are many more and these teams are posting very fast times.

+1: in our time attack and track days. I run 17x10 all around, 245/40 up front and 275/40 in back. I have a much more responsive front end because the streched tires are already "preloaded" and like the above give minimal sidewall flex.

Most guys who drag race dont normally understand these concepts of HPDE and RoadRacing. And besides, The G35/350Z were built for the circuit..not so much for the strip.

Old thread I know, but Im looking at maybe running 265/30/19 all around and am worried about VDC issues... You said you only had an issue once - any updated experience? Thats the only thing Im worried about :)

yes that will give you major vdc issues, as well as look rediculous

why is that? the OP said he had no VDC issues with running same size all around... Im looking at maybe running 19x10 +19 all around with 265/30/19 and going really low. Down the road I may go back to wider rear tires, but that is what they have installed already... plus from the sounds of this thread that it would really be a nice well-rounded setup.

drumma022 02-22-2007 06:18 PM

No issues with VDC still and I drive the car HARD with the VDC on when going into unfamiliar turns/conditions. I have ONLY ever noticed a small difference in VDC was when the rear tires were smaller diameter that the fronts and the effects were that the ABS was a hair sensitive.

Nobody has ever given me an example of when VDC flips out to a point that it would effect daily driving.

drumma022 02-22-2007 06:30 PM

Another note on extreme offset/stretched tires:

I recently swapped my spare set of wheels of MB Motoring Weapons:

17x9 +17 255/40/17
17x9 +17 275/40/17

The tires were brand new Kumho MX. After the break-in time and no other adjustments ... The front end is much less responsive than it was on the fairly worn RT-615's. In fact on the one of the fastest turns on my trip home only could hang at around 65mph where before was topping 78-80mph. Given that the 2 tires are in a similar category of performance tires I can only attribute the biggest factor as being in the offset/tire stretch.

why not jsut disable that ****

drumma022 02-23-2007 08:44 AM

I am not yet as confident with the Z on unfamiliar roads/wet conditions as I would like to be, so I tend to drive with VDC on most of the time. Of course there is the exception of the days where I throw the car onto a wet "skidpad" and depending on my mood, I have fun with VDC off or I also like to analyze how intelligent VDC is at correcting my intentional slides. :)

ihatethatbobbarker 02-23-2007 09:04 AM

i find vdc=unpredicatable car. the only good driver aide is abs, but thats just my opinion.

OffsetZ33 02-23-2007 09:10 AM

Ray,

So do you think there will be any fitment probs running a 19x10 +19 with 265/30/19 all around?

ihatethatbobbarker 02-23-2007 09:22 AM

i think you will, i was at the limits with 18x9.5 +12 on a 265/35/18.

it will always work though, you can always run more camber until it works :D

Luis_23 02-23-2007 09:29 AM

lookin good....

Ive put my 18x10.5 +22 on the front and it cleared - barely... the control arm kinda curves out as it goes up, so I was afraid that a 19 might make it tighter since the wheel itself will be higher up on that arm - hape that makes sense, lol.

what size tire did you have on those 10.5s up front?

smellslikecurry 02-25-2007 01:35 PM

drumma what are ur camber specs and what suspension arms are u running

I had a 275/40/18, but I only put it on the front when the car was up in the air... That tire may have rubbed with the car back on the ground (it is my rear, I only wanted to see if it would fit). The wheel/tire did clear the arm though.

OffsetZ33 02-25-2007 02:03 PM

smellslikecurry - did you end up selling your car or what? I was interested in some of the stuff you were selling :)
