Center of Gravity Question

[Andy]

G-day All , I can't remember the height and width of "Our Feroza " when I first got it but now it's 1800 high x a tad under 1800 wide ( wheels ) is there a formula to use to keep the center of gravity correct , I was once told that if you went up 1" ya have to go out 1/2" . The reason I'm asking is cos the more capable our little truck is the further we go ( terrain wise ) and have had some close calls to doing some custom panel work to the doors

I have no idea of the formula....

But my car being so far off the ground, compared with a standard Feroza, it doesn't feel at all unsteady on side angles or, for that matter, top heavy. I also have hilux diffs (3" narrower than Feroza diffs) under mine, and I've had to compensate with the rims....reversed and offset 2".

I think that the wider chassis under the Feroza may also make it more 'stable' and how close the leafs are to the end of the axle.

So I think you can go up a bit further from where yours is before it starts feeling too 'unstable'.

Thanx for that , amazing the info available on the net 8) 8) 8)

You'd have to either be doing something very serious or seriously wrong to get the rollover stage I think Andy

I did a trip with a narrow track Feroza, 2.5" suspension lift, 2" body lift on 31s, and he put it on it's side, was an amazing angle before it actually went over, and then the rocker panel stopped it going any further....gentle push from 2 guys and it was back up...of course we had to then madly grab for it to stop it going the other way lol! Love deep ruts hehe

Next time I'm going through Menai I'll keep an eye on my inclometer...pretty sure I've had it around 40degrees...

I always forget the angle dangle gauge is there or the angle has passed to see how far over we had been , I always say to myself " don't for get to look at it !!! " Umm yer I think we're all guilty of doing something seriously wrong , Doh

[Andy]

Murray , The narrow track you were talking about , was that Shane's . Have you sent a link the the warf web site owners , I must be the only one that came over from the list

[Ferwoaza]

Yeah that was Shane

Would have to be the slowest layover I have ever seen...tooks us all about 10 seconds to realise what was actually happening hehe. We got him up straight and the flopped back the other way but we caught it in time so no damage done to that side. He's got Mikes old side bars on now, should be less risk.

I learnt long ago, never to follow the same path taken by a Landcruiser with 8" lift running 38s, driven by a guy with the nickname "Maddog"...Shane soon agreed with me on that point heheh.

I sent the email to the list, haven't sent it specifically to Warf owner...

Not bad.....didn't even feel like falling over !!
