with the compeditive scene in QLD heading more toward speed and tight low speed stuff i thought would see if the collective mids on here have any good ideas about setting up leaves for quick events. Aust4, KOR, etc.
Is it absolutly nessessary to spend $1000s on bypass shocks to get a car to go reasonably quick on the bumps.
there are going to be those who will say link it and use coil overs but i know nothing about links and at this stage have no desire to figure them out.

Thicker main leaf, thinner supporting leafs for axle control with anti-friction pads in between. You will need more up travel but on short leafs the ride will be real choppy so longer leafs would be the go to reduce the natural spring frequency. Harder spring bushes for better lateral control of the axle. Some sort of absorbing bumpstops hydro/air I'd say would be pretty necessary to absorb bottoming out. Descent shocks bilstien/koni shouldn't need huge bore or reservoirs if they are not super long courses. I don't think those triple bypass shock things are necessary with the capabilities of the ladder chassis/ light weight/ leaf sprung suspension setup

Try a watts link on the front to get the steering more responsive

Looks like a better version of that style of mounting. All the ones i've seen are just metal on metal. That one at least has a bearing.

The best ones ive seen have plastic slides I recon the bearings would flog out to fast from mud and dirt I have seen a pic somewhere with a johnny joint in the springs instead of the bush to allow more flex

no, King of the rim. Aust4. fast sections, and in the same comp tracks, rock crawling etc.
Im looking at options for making the ute better on the fast stuff.
Defintly dont want to loose offroad ability/ flex etc

What about track bars F&R, and hydro bumps?

I think you will be chasing your tail with this. Even with coils it will be hard. It really surprises me that comps are still run expecting 4x4's to wheel well AND handle the high speed stuff.

bearings are probably less then ideal as they have a hard outer casing and as mentioned the bearing itself won't like the environment. Not a lot of rotating either so the load won't be spread evenly around the race so it will just develop a wear point. maybe a solid brass slide or similar that could be easily replaced as it wears. Need something that will accommodate the twist in the spring a bit as well.
I'd be more inclined to a hard flat spring with an upright shackle, very firm initially then a bit of flex then firms up again, for speed only though, won't flex well. As you'll be locked it will help make up for flex in the crawling

In cab sway bar disco front and rear Hilux fronts allround wirh johnny joints and plastic car slider boxes Panhard rods Hydro bumps Seams like almost as much work just as putting some angled radius arms in and some coilovers Prob end up with as much flex but 10 times as easy to tune

They all have coilovers... But I think that they are primary go-fast tube buggies, that are 4WD with lockers and that's what gets them through the rocky sections... I'm not sure how they would go competing at a TT style event...

Granted its not ideal. But I wont be shipping my car to the states for KOH. And yes the lower class of king of the rim was won by rellow on springs. I reckon I can take him

tanshi,
Have a look at some of the leaf trucks that race at Finke. Should give you a few ideas.

Tanshi im at the same point too, after triple bypass shocks plus hydro bumps its a big step dollar wise, just trying tomake sure it's a functional step forward for a 20year old leaf sprung car. I also don't want to go coil overs and links. So I'll be following this closely

suzuki set up the sierra to be capable on and off road... stock standard theyre a pretty good balance of both.
IMO you'd want to keep it as close to stock as possible so far as suspension goes.

IMO you'd want to keep it as close to stock as possible so far as suspension goes. I'm sorry, I strongly disagree. Standard Suzuki leaf spring suspension is poor for slow technical driving, and although it probably "handles better" than what allot of people's modified Suzuki's would at speed, its harsh choppy ride quality would be a massive killer at speed offroad (mainly a killer of the people in the car's back and arse!).
