I couldn't confirm the gear ratio, but it felt distinctly higher than the 4.625 I'm accustomed to in Roxy. Colin has an intercooler setup and straight-thru downpipe, but it's kind of a 'Mad Max' setup, using his words. The intercooler mounts to the front bumper and a different grille is used.

I'll be replacing the SR wheels with others I have in order to have better tires, probably next weekend. I measured for 33" fitment, but looks like a no-go without a body lift and/or trimming. I'm also mentally wondering whether swapping in a set of Montero difs would be advisable (??), as the truck already has a limited slip. Extra parts include a Starion rear pumpkin with LSD, too.

Regarding the front brakes, aren't they already the larger diameter, like the V6 Montero?
