Hi everyone.
Just a thought, thinking of 5th and 6th gear ratios in my 2.8L auto prado. They seem so tall that the 6th rarely gets used (or hunts constantly between 5th/6th). I've looked at some diff/drive calculations and considered the following:
4.11 gears Nitro front/rear
4.56 gears Nitro front/rear
I currently run the normal sized 265/65/17 (KO2s), and currently pull ~1650RPM at 100kpm in 6th (GPS, 105kph speedo). Im considering upgrading to 32inch (close to it, 265/70/17 (31.6")). With that setup the calculations are
3.909 - Current ratio @ 1650 100kph (30.6")
4.11 - Nearly 1700RPM for the same speed. (31.6")
4.56 - Just over 1850RPM for the same speed. (31.6")
I am thinking of the 4.56 as the slightly higher revs might fix some sluggishness issues, and allow it to hold 6th easier on the highway without dropping to 5th (2500+RPM) all the time. The kits are around $1350USD which is front and rear. I am wondering if I have failed to consider anything here? In the near future, and before doing the ratio I will prob install Steinbauer, and was thinking of doing a rear E-locker at the same time. If anyone has done anything similar please let me know the info, I've searched without success.
Thank you,
