315's and speedometer
If I put 17 X 11 wheels and 315 35's on the rear of my (non ZR1) 94 will it make the speedometer incorrect as the tire diameter is different? Or is this a non issue?
I tried to search and didn't come up with anything.

The tire diameter isn't different by much if at all. Truthfully I never did measure to see the difference if any.
My speedo seems to be right on since I pass those RADAR machines on the side of the road and my speedo matches what the RADAR says.

As the other have stated you will be fine.
285/40/17 tire - 25.98" diameter
315/35/17 tire - 25.68" diameter
You can see that it's only a difference of 0.3", which is negligeable because your speedometer will only read 0.7 MPH too fast.
