Triblkcobra, SpeedCal question, just changed rims/tires

[GToddyT5]

I went from my stock 16s w/ 225/55/16s, I believe, to 245/45/17s. Do I need to change the dip switches on my speedcal? I have the extended-range version.

You may need to change the switches. Go to dallasmustang.com and use their gear ratio calculator to determine what the effect of changing to the new tires will be. It will show you what the switches should be set at.

I got mine straight from Triblkcobra, it's not the same SpeedCal Dallas sells. It is an extended-range SpeedCal for a wider range of corrections.

Hey, I already answered this over on the Corral right? If not let me know.
