GT500 Standard Wheel to SVTPP Wheels Question about swapping
I'm putting a new set of wheels on my 2010 GT500; they are the SVTPP wheels/tires off of a 2013 GT500. Someone mentioned that my speedo will now be off. Since I figured it wouldn't be off more than a couple MPH I didn't figure it would be a big deal, until I heard I would be accumulating mileage on my odometer faster than usual. (Front tire/wheel size are identical on both sets, the only difference between the rears are 19" vs 20" wheels; tire size are both 285 35 19/20) I'm wondering if:
Will my odometer actually accumulate mileage quicker because of this?
I've heard an aftermarket tuner will fix this; I want my tune and everything to be kept stock, and I don't think buying one will be worth it just to correct my speedo. I'm wondering if I borrow one of these tuners from someone, or get a used one will it still work, or do they stay paired to one car and one car only?
If you have any other solutions/tips on how to calibrate my speedometer that would be very helpful! Thank you.
