Issues & Defects from factory

My speedo is also close to 10% over actual speed, this really annoys me. Having to calculate your actual speed if you are coming up to a speed camera is ridiculous. I don't think it unreasonable to expect my speedo to tell me my correct speed. Apparently in Australia speedos are allowed to read up to 10% high, but they must not read lower than actual speed.
Why they can't get it closer than 10% I don't understand. It is to improve the 0-100 times (actually 0-91) ? Does anyone know how it would be adjusted in Nissan did it ? Is it an electronic adjustment ? Can the Dealer Service do it ?
I am hoping that a new set of 19" rims with different profile tyres will make the speedo read a bit closer to what it should be anyway.

My biggest issue with reading over the actual speed is that it encourages speeding. We all know that 100 is not 100 so we get used to doing more. It's hard to do 108, so we settle for 110, which is actually a couple of Ks over - assuming 8%. Then you start getting complacent about exceeding the speed limit and the limits don't mean much any more. It's OK to do 70 in a 60 zone but that's even more over the limit.
If the speedo read what I was actually doing, I'd have a hard limit - the speed limit. At the moment, I just don't care that I'm going to fast because the speedo always reads way to high.

My 0.018USD worth.

I just think of it as a way to avoid speeding fines. I usually just cruise at the 100 mark, but I'll go up to 105 sometimes which is really about 96-97kph and sit there. I feel like i'm speeding but not.... we all win.

I have to agree with you there BluZ, I take less notice of the speedo as it appears so far out, and usually settle on what feels right especially on the highway. I know it's not the right thing to do, but I was wondering why all and sundry were overtaking me when I picked the car up from Sydney.

I think if the speedo is 9% out like that it makes you 'estimate' what speed you are doing which isn't very safe. I'd rather it be accurate. We aren't going to just sit on the highway doing 91km/h when the speedo says 100km, we'll be guessing all the time. If the speedo says 100km/h and you are doing just 91km/h then it makes a big difference over a long distance trip. I'm worried one day i'll get a ticket for being a few k over because my speed estimate wasn't correct. I used to hear about other makes and models having their speedo out by that much and used to think 'how crazy is that'. I never expected the Z to have the same issue. Is there a way it can be adjusted in a service?
