Re: Need Advice on body lift
Okay, you likely have 3.07 diff ratio. Your AX-15 transmission ratios
are: 1st:3.83, 2nd:2.33, 3rd:1.44, 4th:1.00, 5th:0.79, Rev:4.22
So, with 28" tires in 5th at 65mph:
(3.07 * 0.79 * 65 * 336 ) / 28 = 1892 RPM
That's already pretty sluggish, so you'll not use 5th much if you get
31" tires (1700 RPM @ 65mph). Nice thing about a manual though is that
you can live with it - just cruise in 4th:
(3.07 * 1.00 * 65 * 336 ) / 31 = 2162 RPM
.... which is a nice cruising RPM at that speed with heavier wider tires.
You'll also kiss 5th goodbye with 30"s, so may as well try the 31"s.
