Diff widths

So with people building buggys/tuff trucks to try and suit multiple events, what MWS-MWS or overall width are people going for? The americans all seem too wide for our stuff particularly if you want to cone dodge aswell.

Im leaning towards 64-66" WMS - WMS with positive offset rims at this stage but the wider I go the easier it makes it for me.

Re: Diff widths

Basically I have the same idea with my approach. I will be running 64-66" WMS with front being 1-2" wider so fr 66"- rear 64" based on a 110" WB. I will be running as +'ve offset as possible to be overall track width no wider than 2100mm.

Re: Diff widths

My buggy is 69" in the front and 64.5" in the rear.
Ill be getting positive rims but don't want the hubs poking out so will be limited to offset.

In put my -44 wheels/tyres off the bundy and it measured up 86" in the front so a bit too wide

Re: Diff widths

Stock chevy D60 front with solid hubs. Keeping it stock width for ease of axle choice and availability.
It's only 3" wider than what you wanted

Re: Diff widths

Are you only doing the fast stuff with yours Evan? Prob wont make much noticeable difference. Id like to push mine out too 69-70 but I think itll make it to painfull for tuff truck.
the navara was 68 wms wms and shitty steering angle.

Re: Diff widths

I'll be using it for crawling and social stuff too. Mine will be setup for 50deg steer lock.
It's cant be too bad plenty of factory housings used in the US.
But time will tell. It's under the buggy now ;)

Re: Diff widths

3" is still 3" & then rim offset. Tight tracks are going to make or break a few people.

Re: Diff widths

1.5" each side and positive offset wheels won't be that bad.

Will be pretty shit if an event is run based off the American style of racing but make it to suit a cruiser diff..... :?

Re: Diff widths

Creek runs aren't always highway width, to base a series on another country like Aust4 & our Ultra4 are doing is great. But to think that we are going to run events with same terrain as in USA is naive to say the least. We can only do the best with what we have available. That is just the way it was always going to be. I know for a fact that some of the creek runs up here I will even struggle which is why I am still up in the air with 65" or 66".
I want to run a very positive set to keep below 2100 & base setup on that. If course allows wider track I will run spacers or 2nd wheels with different offset to help the stability with speed that a wider track will obviously allow.
It is much easier to add width than take it off when setting up suspension geometry as removing width can be detrimental to suspension when adding has less effect.

Re: Diff widths

i never expected to have the same terrain as america, we dont have that kind of landscape readily available.
but when the even is aimed at the ultra4 styled buggy and with alot of the chassis from the states based on wide diffs that where my comment came from.

i dont really care, ive picked a diff thats going to be strong and reliable and its stock width so have ease of stock parts/axles if needed to get out of trouble.

if its too wide for some of the events then i wont do them or pack a chainsaw :D

Re: Diff widths

With diff width I just thought well the widest car down pretty much any trail in Australia and that would be a gu patrol so stayed similar width to gu diffs I'm at 65" in the front and stock gu in the rear in the rear wich is 63" I'm pretty sure with neg 30 rims, I've always liked my front just that little bit wider as I know if I can get the front through an obstacle I should be able to get the rear through pretty easy. Too wide can cause dramas not only on the trail but with getting it on a car trailer I know ill be making a new trailer to suit as I'm not swapping wheels each time I need to load it on a trailer.

Re: Diff widths

I'm 70.5 wms

It's wide but I've been able to use minimal offset rims, steering is light and responsive, rims are stronger.

I do clip trees more regularly nowadays 1 of which spun me off into the bush.

Try these to places, Jmac used to do a lot of 4wd stuff and Craft differentials used to do a lot of speedway, if they cant they should know who does

Where are you based?
I know a guy in Melb involved in the original Rockcrusher axle design and build (which later became Solid). If he couldn't, then he would certainly point you in the right direction.

Re: Diff widths

Why not run a 64" wms and if it feels too narrow just use spacers?

For my set up I want the width for longer axles, better cv angles.

Agree Josh, plus spacers are just another bolt on that can cause issues

Re: Diff widths

I will be running at 67" wms for the front and hopefully a little less in the back. At least with 67" wms on a D60 front you can still use all production parts so spares are easy to get you just use ford and Chevy axles. I think this is the best compromise between width and availability over here.

Re: Diff widths

What sort of overall width would be best for an all rounder buggy. My main use for the buggy will be social wheeling but would like to be able to run events like Aust4 or tough tracks.

The more i think about it im leaning towards keeping it at Patrol/Landcruiser width at a max as there the most common vehicles down the tracks that it will see, but i noticed brooksy mentioned 2100 which is wider again.

2100 to me is absolute max outside of tyre width
