6" lift 34" tires speedo correction and re gear

Looking at doing a 6 " lift and 34 in tires my questions are as follows

1. What are you doing if there is anything to do to correct the speedo?

2. What did you re gear to go back to factory like torque, pull power ratio ect. ?

If you didn't do one or the other or either please elaborate why I.e. pro/cons or just didn't do it.

Thanks guys & gals

 

1. Speedo Healer or similar device
2. I don't know Tacomas, but FJ Cruiser with manual trans gears is very good with 315/70R17, absolutely no need for regearing. Different situation with automatic.

 

Wish I found a 6spd lol
