Based on the number of parts that originate from down under I would surmise that Snowbum is an Aussie, so first of all, welcome to the forum. Busta's comment that Snowbum does the same sort of thing that he does is well of the mark as getting lost in the outback is not just a short walk to a local farm asking for a tow out, it really is a matter of life and death which is why Snowbum wants to build the ultimate " get me out of here" Jimny.

fordem.

I would be interested in your before and after figures for your correction bushes. As soon as it stops raining and the blue tits have fledged, I will take some measurements and see if my memory is still active enough to work out the present caster angle.

Negative 1.2° before correction, positive 1.1° after.

The only suspension work between the two measurements was the removal of the arms, OEM bushes pressed out, OMECA001 bushes pressed in and the arms reinstalled.

The first measurement, before fitting the bar and the suspension was positive 2.1°

What's your experience of working and travelling in Australia Roger?
When I was out there I learnt pretty quickly that there was a lot of merit in keeping things simple, as often the modifications were the things that caused failures. We even stopped fitting snorkels to the work utes because they were sucking in more dust than the standard intake, not less. I toured Western Australia on dirt roads in a 20 year old Volvo estate and a completely standard 20 year old Nissan Patrol. The Patrol was overkill tbh, I wish I had kept the Volvo, but I would have loved a Jimny back then. Unless you're going out of your way to seek a challenging route, you'll be sharing off-road touring routes with grey nomads in standard doublecabs, familys in SUVs and backpackers in Toyota Hiaces. It's not all as extreme as the Youtubers make it out to be.

There are also universal alternatives that better solve a problem than a modification does. E.g. having a good battery compressor (e.g. Makita, Milwaukee etc) rather than having one bolted to the car somewhere getting full or dust, cooked by heat off the engine and shaken to bits even when you're not using it. You'll use the cordless one much more often.
A "winch in a box" setup rather than a winch permanently fitted to the front of the car means you can pull anything from any direction. This is much more useful for general farm and trailer jobs, and gives you more options during a vehicle recovery. Going forwards is rarely the best way out of trouble! I've sold mine due to lack of use but I had a 4,500lb winch on a towball bracket that would sit neatly in the rear passenger footwell, out of sight and away from harm. The long cables with crocodile clips that powered it doubled up as jump leads.
A Jackaroo type powerpack powers all your accessories in the car and your camping gadgets at camp and your house during a power cut. That's much more useful than an extra battery in the car. And Noco type jump pack removes and worries about flat batteries.

Regarding trailers, I know standards are different in Aus, but in the UK we have 50mm tow balls and over-run trailer brakes and honestly they are more than adequate for off-road towing behind a Jimny. I'm sure a simple electric brake setup would also suffice. A sensibly sized single axle trailer, loaded correctly, will go wherever the Jimny goes and you'll barely know it's there. Mine is around 1,300kg loaded, about 70kg nose weight and I sit very comfortably at 100kmh. If you can get a trailer with Jimny wheel fitment that's great, but it's not a common tyre size or bolt pattern for trailers. I wouldn't get too hung up on this.

I have never been to Australia but I can read and I get regular updates from people who walk the walk and not just talk the talk.
Snowbum wants a bullet proof Jimny and from his questions, he has obviously talked to a lot of people and now he wants our input. Get it wrong in the UK means a call on your mobile to the AA. RAC, or Green Flag or a local garage to come out and take you home whereas getting stuck in the outback can be life threatening. I stick with my original comment.

Thanks fordem.

Looking at your figures I surmise that out of the showroom your Jimny was close to optimum with a serious drop to the neg. of 3.3 deg. This was partially corrected with the correction bushes to a figure of 1.1 deg. positive. So a 50mm lift ( I assume ) will take the caster angle out of spec. even if the original figure was on the high side of 2.92 deg. positive. I don't know of any people local to me ( Redditch ) who I would trust to measure the caster as is ie just the 50 mm lift but as I type a company who service the Audi may know of someone they would trust so this . issue is "work in progress". Many thanks for the info.

Caster "measurements" were done on a John Bean alignment machine - essentially just set the car up as if you were going to have the alignment done, and stop before any adjustments were made.  A picture of the screen was then taken so as to have a record of the measurements as the shops here generally don't have a printer attached.

The suspension is Old Man Emu, which is described as approximately 40mm of lift, measurements at the time of install show an increase between 45 & 50mm, ideally a second set of measurements would be done after a thousand miles or so, as some settling is expected, I haven't yet gotten around to that.
