157,237 miles on it it does have nismo rims.Depending on which '03 Z33 you own, the stock wheels were either 17" or 18". Standard tire sizes were smaller than what you have now, so it was definitely changed from the way it was delivered from Nissan.
How many miles on this Z?.
Back on the original ABS/SLIP/TCS lights. 90% probability it's your tire sizes; that is, the 40 aspect in the rear. The 255s at 27.03 O.D. are 4.8% delta compared to the front. OEM setting is ~3% +/- 0.25%. The traction control system (or VDC if equipped) is "seeing" (from relative F/R wheel speeds) that the fronts are spinning faster indicating to the ECM that your front end washing out and invokes traction control (brakes and engine cut back) to bring the car back into control (or "good wheel speeds".)What if there deep set rims , I'm running 245's now with rims that put the hubs nearer to the outside of the wheel well.
