    Hill Climb Comparison

    The other day we had a look at Janowen Hills, a camping/4WD place near Brisbane.
    Last thing before leaving was this small hill climb, which was steeper than it looks.
    It's an interesting comparison, I make harder work of it (first vehicle in video).
    [ame]https://youtu.be/ZylNtWfhKQM[/ame]

    The differences between vehicles are (EDIT: both in rock crawl):

    Me
    B'stone D697 265/60/R18 (30.5")
    30psi and half worn

    James
    BFG KO2 265/65/R18 (31.5")
    25-26psi and maybe 25% worn (guess)
    Equipped with e-diff

    Not sure what makes the most difference to the composure? It certainly felt more scrabbly than it looks & James had minimal slipping.

    I suspect it's mainly the tyre pressure combined with less tread on the D697s.
    And probably I needed to back off just slightly when wheel spin started, which seemed to work quite well on another scrabbly/rocky pinch that didn't get filmed.
    It is quite a fine line to get the best throttle position for maximum control.

    Cheers,
    Scott

    Yep, rock crawl. Good point, will add to summary.

    If all else was equal (TR mode chosen) I would say tyre pressure and the rear e-diff. James's rear end was definitely less scrabbly than yours.

    Was an interesting watch though!

    Slightly different front end line too.
    If you'd aired down it would have been closer.

    Your rears span independently and your vehicle lost progress at the same time. The lack of e-diff is quite obvious.

    So it maybe was worth the months of searching for an e-diff

    Yes I reckon it was but I also agree with Tombie that the tyre pressure didn't give mine an equal chance.
    Obviously more testing is in order.
