Speedometer correction (switching to 4.10s) - ZR-1 Net Registry Forums

I know there are different ways to do this. I am curious to see what everyone else has done and if they have had any issues with their method?

Some use an electronic box to accomplish it while other do the Drive/Driven gear swap in in the trans.

I know the drive/driven set from Marc is listed as a 1% error which is fine, but just curious what everyone else has done
