whats the ultimate wheel base
no f#@k wits need reply
i wish to kno the pros and cons of different wheelbases
and the peoples oppinion of ideal

will depend on tyre size etc your running on your truck.

The next smart ass reply will be banned for life!

The guy has asked a simple question if you cant answer it then Shut the Fark up

My buggy will have a 105 wheel base, why? I think its a good compromise between break over angle and stability. I never had anything this short before and have basicly only decided this as it is in the middle of a shorties wheel base (which is too short) and my hilux (which is too long)

Ive got a FJ73 MWB cruiser, would like to think ive got the best of both worlds. Short wheel base seem to be like a jack rabbit lol where as the long wheel seems to wallow.

My opinion (hopefully appears to be a valid one as dont wanna be banned lol)

need to know more 'specs' about the rest of the truck...will depend on everything from tire size to weight and more importantly what it would be driving on...

bundera with extra cab chop (to be done at same time)
and 35's
i like to drive most terains but dont like how shortys stand up
nor do i like how wagons bottom out
guess im looking 4 an idea on whats the happy meduim

Whichever amount you choose, it is always a compromise. There really is no "ideal" wheelbase. "Midwheelbase" will have a combination of the best and worst of both short and long wheelbases. 105-115" seems too be acknowledged as a reasonable midwheelbase length and the best compromise. (SWB zook 88", GQ Patrol ~122" - correct me if I'm wrong)

a few mates who have the mwb conversion (102inch)on their GQ's wreckon they are just about right for comp work as they lose that edge of wanting to wheel stand on steep climbs but arnt too long to bottom out. For what you do, maybe a 100 inch or slightly more wheelbase will suffice with the size of your tyres.

Just my 2c,

i have a GQ SWB, which is in the middle of a ute chop, then ill be onto wheel base extension, factory it sits at 94" and im hoping to get out to 104-110, might get to about 106 i think at this stage,

Short wheel base 90-100 is good for tight tracks and uneven ground (less chance of bellying out) and max 38" tyres, 110+ is good for 44+ tyres and steep climbs, 100-110 is best for average Joe that wants the best of both worlds, steep climbs and tight tracks.

That’s my view on the world of wheel base, but this Q is a bit like " Whats better manual or auto", or "Whats the best tyre" U are going to get so many different opinions.

Have a SWB GQ which I believe is something like 98". It's too short for some of the more scary climbs (I've backout out of a couple from fear factor and lack of front locker).

But the roughly ~130" stuff like LWB Defenders and GU's can struggle in the tight stuff, and it can also be pretty hard keeping both ends on a ridge on a twisty trail in a LWB.

In the end you would build for the type of work you want to do.

I'd love maybe another 6" of wheelbase though. I think about 105-110" would be ideal for the sort of stuff I do.

I've found 100" to be a perfect combo with 35's, esp if you can keep the truck low.

It rarely feels like it wants to go over backwards, but it also dosen't bottom out very often.

My brothers have rovers, 100inch and "the 109" , i had a 109 leafer, hated it, with coils power steer and 35's the 109 is awsome up hills, the 100 inch lifts a little up hills, but still not enough to worry u.
My ideal wheel base would be 107 like an early series 1 landrover lwb

my 2 cents

105"

depends on a lot of other factors, but i think:

105" for competitive rock crawling.
110" for straight out driving big stuff.

I reckon the ultimate wheel base is one that you can change on the go...

...as in a winch on the rear diff, pulling the front diff backwards, whilst you gain a bit of height. Got it all sorted out on me tube buggy plans.

Or shove some hydraulic rams as rear trailing arms to pull/push the rear diff. Simple.

i think the best WB for me is 117''

110"

I see your 117" and raise you to 118 1/2"

100" 35" tyres
105" 38" tyres
110" 42" tyres

100.5 for a buggy
104 for trail rig

95" gotta luv em short

I've been thinking about this (because it beats thinking about more important issues ) and I'm wondering if there's a few basic guidelines?

For instance, ramp-over angle is probably important, which is affected by clearance under the belly/chassis rails (rather than diff clearance) and also relates to tyre size.

Short wheelbase, small tyres could have same ramp-over as longer wheelbase and larger tyres, but would have smaller clearance.

That's OK - 'coz I'll just lift my shorty to the same clearance, and I'll have BETTER ramp-over.

But then it may be too pitchy/unstable?

Hang on. Instead of lifting the suspension, I'll chop the guards and whack in some MASSIVE tyres! I've now got the big clearance, got an EXCELLENT ramp-over angle and I DON'T have the huge suspension lift! But it's still almost as tall as it is long, and looks like a full-scale promotion for next season's hot new kiddy toy.

So I'm guessing PROPORTION is an important word here - but what works and what doesn't?

For the record, I've got 33" tyres on a wheelbase which is supposedly 95" - and I think it would be too short for competition work. For touring it's a little pitchy, but for the tracks to which I limit myself (such as the medium/hard tracks around LCMP) it's a pretty good package.

Cheers,
