Hmm, im not sure but i think it might be because either your tires are worn out or your back wheels are too small and its tricking it into thinking when you are slipping.
Thats just me though

im not sure how the sensor system works back there (New z owner..) but it sounds like its some sort of sensor malfunction if they are the same size tires etc etc

My understanding of that slip light is the rear end is spinning faster than the fronts, and if it goes more than a 3 or 5 percent difference between the two, that light comes up so you know you are losing traction.
So, I would guess that extra 20MM*.45, so there is a 9MM difference in tire height. I would guess that that difference is not enough until you get into some real speed (ie: more revolutions of the tire per second multiplied by the difference) you finally hit the max limit and the computer thinks you are slipping. At least, that's what I would assume, and I think the slip light is quite common when people swap tires out.

Well, here's a quick fix for you, and I don't mean to sound rude or condescending.
1: Until you can perform step two, this should suffice, though you should be more careful while you drive: Press the TCS button on the dash. It'll turn off your traction control system, eliminating the light and the "slip" problem for the short term.
2: Go to TireRack.com, order new tires in the correct size, and have them balanced. I would recommend you do this immediately. Remember: you might save a couple hundred bucks in the short term by putting your old used tires back on, but if one bursts and you total your car, you just cost yourself twenty thousand dollars or so.
Of course, you might know that, in which case I would simply be blowing hot air. But either way, I'll have at least done my duty.
As for the cause, as was stated earlier, it could be a difference in wheel/tire diameter, width, rubber compound (old tires tend to get kind of hard, so they don't stick anymore), tread, or perhaps a sensor fault.
If you replace the tires and the problem persists, my recommendation would be to visit a dealership and be very specific about your problem. Dealers aren't exactly the most inviting place to have your car repaired, but in this case, it may be the safest unless you can find someone experienced in dealing with Nissans, and specifically the 350Z.
Hope that helps.

I think this has been answered, but it’s probably your fronts causing the problem. Your rears are within specification as to overall diameter, but your fronts are not tall enough.
Stock Size
F-225/50WR17 Overall Diameter: 25.85 in
R-235/50WR17 Overall Diameter: 26.25 in
Your Size
F- 225/45-17” Overall Diameter: 24.97 in
R- 245/45-17” Overall Diameter: 25.68 in
If you replace the tires with new ones, and want to go 245mm (hardly any difference from 235 mm) width, consider mounting 245/50-17” on the rears (Overall Diameter: 26.64 in). Since the difference is miniscule between 235 and 245, I would get the stock size (that insures proper TCS function).
