Doing a soa on the front with stock leaves turned around and was wondering how many leaves people are running in the front. Not sure if I am gunna do shackle reversal cause I am not turning the knuckles but I hear it can be done with stock leaves. For the rear I was thinking of running either yj or xj stock coils with a traditional 3 link/panhard bar setup. Anyone run these and how soft/flexible are they when compared to the front soa springs? Also running wangoneer axles front and rear.

Actually YJ's never came with coils, so it would kind of hard to do this setup. Just giving you a hard time.
I am setting up a custom coil front end on my FJ40 using ZJ front coils and it seems to flex pretty nice. Although, I haven't really had a chance to trail test it.
A good friend of mine is setting a YJ with coils in the rear that are off of a TJ. There are stock height right now, but he will eventually get lifted ones. He has to considering he will be running 42" tall tires.
If by panhard bar, you mean a track bar, I would try and avoid it. A track bar will limit the amount of flex that you have. Go with a three link design that uses a upper y-bar, or just go the tried and true four link. I have two friends that run a four link that they built and it works great.
Also, if you are going to do a SOA in the front, I would really try and do a shackle reversal. It is pretty easy and turning the knuckles is not too bad as well. It will ride so much better. I know a couple of people that don't run SR and they pretty much all wish that they did. But is is not really an issue if your rig is seeing strickly trail. Not running a SR will help you on some trails and hurt you on others. HTH

My bj42 has coils under it.
I use a 3 link with a panhard rod in the back and it is ok, but I have to have a massive z panhard rod. With high lift you have problems mounting the panhard rod flat. If you lower the mount off the chassis/ raise the mount off the diff the mount is weakened alot due the extra leverage.
I am going to go to 2 lower trailing arms with an upper a-frame in the rear as well as the front. It will flex better and position the diff better too!

Sorry about the typo as I ment tj. I have done similar with jeep using toyota rear springs in the front and aerostar coils in the rear but I know cruzahs are pretty damn heavy so I thought a little heavier coil would be better. Thanks for the info, I'll probably just stick with building a wishbone 3 link like I have on my toy but I have seen people with a panhard in the rear and it seems to flex just as much as with 4 link so I don't know about the non flexy statement. Thanks again.

My reasoning on the panhard rod limiting flex is from watching TJ's with the long arm kit. Most of these kits if I remember right still use a track bar. If you compare them to rigs that use a pure four link system with with no track bar, they have a tendency to flex easier.
Also from talking to people about it, a triangulated four link system is stronger and safer than a five link system that uses a track bar to locate the axle from side to side. Just my opinion, but I really trust the people that I have talked to. A triangle shape is most always stronger than a square or rectangle.

with the panhard in mine it still flexes really good, it does pull the axle from one side to the other when it flexes though, but it isnt a problem.

When I did mine I under estimated the force the upper link takes. I am changing mine so I can get more strength for the upper link and also you can get rid of the panhard, which I dont like.

I am glad that your system works coiledBJ42. I am not saying that it won't work fairly well, just not as well as a true four link or 3 link with y bar. This is just my experience, but I am by no means an expert.
Although, I just read something tonight on the board that makes sense about have a panhard rod in front. If you are still running a conventional steering system, it is helpful to run a panhard rod that is in line with your drag link, because it will help to eliminate bump steer.
I haven't fully thought this one through yet or mocked it up, but it makes sense just mulling over it.

CoiledBJ42, I just noticed that you are from Sydney, Austrailia. I just have to say that is one of the coolest and sweetest cities I have ever been to. I loved that place so much, even though my family and I only spent five days there.
Ever since we came back, I have been dreaming of a way to get back there. I am currently looking into a way to try and move there for a short while. I have a couple of friends that studied abroad there and they said it was the time of lifetime. I know that for a US person to get a work visa is next to impossible. Although, I did meet some US people that were working at resteraunts and such. Enjoy that sweet city of yours and hopefully you guys will end up getting the next olympics if Athens falls through like I think it will. That whole country is close to bankruptcy. You guys put on one of the best Summer Olympics there has been to date, and I would love to see you guys get it again.

The thing with the front is that the axle HAS to hold it sideways position really well. In the front of mine I run a similar set up to what Slinky from SRC runs in the front of his. Instead of a radius arm I used an upper and lower trailing arm. It doesnt hold the axle in position well enough.
When mine flexes up in the front, I run out of steering lock. The wheels will be pointing full left and the steering wheel is full right!!
I only have stock steering in it at the moment. I am told that going to 60 series steering box will help alot because the box actually throws further.
If the panhard it not flat it doesnt bump steer what it does is push the axle sideways when the suspension goes up and down.

The draglink also has to be flat because that will cause bump steer. As the suspension moves up and down it forces the wheels to turn one way and as the suspension rises it pulls it the other way. As it does this the car goies uop and down harder which cause the wheels to flap side to side harder.

Just because the panhard and draglink are parallel it doesnt mean it wont bumpsteer. They both should be flat, simple as that.
I know cause mine werent and it was FUCKED!!
I have had to z the draglink and the panhard in the rear to stop it.

I have actually wheeled with Slinky (Sam) from the SRC out in JV. If I remember right, he was running a four link when I say him. Maybe before that he was running a radius arm setup, but I am pretty sure it was a four link setup using tractor links.
In the rear of his, he had a triangulated upper and lower y-bar setup that secured opposing each other. He said it flexed great and had no rear steer. It was a kick getting to watch that thing crawl. I actuallly have quite a few photo's of it.

Yeah, he has a 4 link with the upper links triangulated in it now.

I was thinking of going to a double a frame setup in the rear of mine, but talking to a few people they tell me that you get PLENTY of flex out the lower trailing arms and upper a-frame set up.

Sydney is ok.
Some good trails. Porters road is good. Check out http://www.homestead.com/offroadrig/portersroadpage2.html

It has some ok pics of porters.

You sound as if you are not too fond of Sydney. Have you lived there your whole life? If that is the case, then I can understand that it wouldn't spark your intrest the way it did for me. Granted there may not be the best trails in the world there, but Sydney is an awesome city.
I have been to quite few cities around the world and it is by far my favorite. The only other place the comes close in coolness factor is some places up in Canada.
I like living in the US, but I do want to get our and live some other places as well. Besides, you have some of the most beautiful women I have ever seen. I would love to find myself an Austrailian wife. I have never seen so many blonde haired, blue eyed beauties in one place.
Although, I haven't been to Scandanavia yet, but hopefully that will happpen this summer.
