Rim swap 18's -17's...

[MikeyBlacks]

I was just wondering I currently have 18's on the car & was wondering when I goto the track with the 17's do I have to change anything in the xcal 3 so the speedo isn't off ? Or can I just leave it be...Thx Mike

No real reason for you to be concerned with your speedo at the track. They should have timing equipment


But to address your question. Wheel size has nothing to do with your speedo. It is the tire height and revs per mile.

It's not rim size that matters anyways, it's tire diameter and revs per mile to adjust your speedo.
