Flexy Coils and Mathematical Theory for Review

Apparently not :). But now im going to go measure exactly what duration they become active in order too bang and clang.
 
I've never heard, nor heard anything about.

All of the info provided came straight from Shane and have the emails.

About to order the coils with disregard to the spacer suggestion and if/when they clank, will start a new plasti-dip thread.

PS rear 545mm
DS rear 560mm

25mm, or 1" shorter than what I have know.

Is it possible for there to be a legitimate answer that says I'm in the right direction, or not?

My question is why the obsession with these flexy coils?

It would seem that it is to much trouble for not a lot of real gain in performance over standard springs

I am all for out of the box thinking but with an 80 it is a little bit more difficult because there are very few that have done it
 
Roger, thousands of people run flexi coils here and would never look back. Its a solution to a problem.

Take the rear suspesion for example. What do you think is better and why. 6" linear coils? or 3" linear coils and 3" spacers?

Have had good luck with similar design on the FJC.

It does open up what little bit is available beyond a coil that will fall out or have no downforce.

I do have longer shock travel capabilities than are typical, but can't say if a benefit will be noticed off road, yet.

If it is, I'll be sure to keep it on the build page, to avoid this BS again.

Not obsessed.

Bought them, needed to make adjustments to the coil lengths, so asked for help in checking my thinking and a s*** storm ensued.

My bad.

I'll know that if it's not the fifth thread of the day about birfs clicking, tire size queries, or any number of the repetitive topics typically seen on Mud, that it can't be handled and it'll become a source of ridicule.

All I was hoping for was assistance in determining what coil heights to order, beyond an "OME Heavy" and it's too much for this forum.

In case it's not been noticed, I don't half ass anything. Why would I start now, at 80% done?
 
Arewell Rogers gone. To answer my own question, a 3" coil with 2-3" spacer drives much much better on road. Now change this coil to a 3" progressive and it drives great when loaded up and unloaded.

Offroad, Rear suspesion. The rear travel is great from stock.

Tuck
Bumpstops are adjusted to just before the tyre binds/fouls anything. A 6" coil will hit these bumstops long before it actually gets close to where is would if the bumpstop wherent there = wasted coil energy. A 3" with a 2-3" spacer will hit the bumstops aswell but be very close to where it would be sitting if the bumpstops where not there.

Fall/drop
The 6" coil will remain seated for much longer than the 3" with a spacer. Some people are happy with this and just use drop out cones to stop them falling out. But your actaul travel was inhibited (great tuck, restricted fall).

Now replace these spacers with a thin coil wind with a great open length, but also completely colapses under normal body weight and works like a spacer. When offroading and called upon during drop/fall they continue to exert dowward forces for much longer, coils will remain captured even with loong shocks, 4x4ing ability improved as the extra downward forces at long travel = grip.

Hope that explains it a bit better.
 
You know what's so ironic?

Pitched the same coils to me on the rear of the FJC two years ago and I bought them from MetalTech for the exact same damn reasons that have been highlighted all throughout the 80 forum on Mud.

It's funny to be ridiculed for seeking the same "performance" that I was sold on the FJC, like many, many others have been and still are.

I bought into it, then. Think it works, but maybe because I'm stupid.

If that's the case, I was just as much then as I am now, because it's the same damn principle and design.
 
I have no experience with these flexy coils on the 80 series but it sounds like the same concept as our long travel spring for the FJC. For all intents and purposes the top half of our spring sits fully collapsed at ride height and starts to open up on down travel hence the ability to flex beyond a standard 2" spring.
 
Delancy I am in no way ridiculing you for your efforts

I know from reading your build that you spare no expense and that you are trying stuff outside of what is normally preached here on mud, and I applaud you for that.

I wish I had answers for you, but as you know you are using gear that very few if any use here in the states and you have o try and get answers from abroad, it is kind of sad.

Most 80 owners on here have tunnel vision and wont look outside the box and do what is considered the standard and for the ones that do they get criticized and ridiculed.

More power to you.

God for bid if you stray off the path man what were you thinking its all about clicking birfs, crappy mpgs, and normal operating temps:p

Oh wait forgot a few:
"Ok another help me with my suspension thread"
" Another tire thread"
 
Been debating on whether to respond on this thread as I skim read it.

1st thought: put a fat chick in the back and it's level. Drive it some and the spring will settle in some to 4" lift

2nd thought: I have run 16" triple rate coil overs on the street and the whole idea is the same as the flexy coils. Only tunable on when it transitions from soft to street occurred.

3rd thought: if your anal about a half inch difference get coil overs and adjust to your very need after every 10 miles stop and adjust for the lack of a gallon of fuel in the tank

4th I can't believe I waisted this much time

5th I have been responsible for spring manufacturing and its not as easy as you think. There is a lot of variation ft to ft in spring steel and unless you want to pay government rates for a perfect spring and $1k hammers and toilet seats you hear of, learn to live with manufacturing variation that keeps products reasonable priced to the public
 
6th i'm as anal as you and will end up with coilovers just saving funds oven if its for 8" of travel and a 3" lift
 
I have not gone back through your build thread but I can't recall seeing any pics of your rig with the standard aftermarket bumper options with spare tire hanging off the back. I am also fairly certain you were shooting for an ultra light rig? When I ran with no back seats at all, no spare, no bumper, and even stripped oem bumper stuff the truck sat super high in the back with "stock" ride height OME coils. If the 4" lift was based off a standard spec'd land cruiser with all of the standard add ons I can see why your heights are messed up. I could only assume with a full bumper and hanging a 37 off the back it's going to come down to what you are looking for. Just a thought anyways.

Thanks for trying all of these parts too, you seem to be the only one doing new things these days.
 
If you haven't heard the flexy coils bang and clank, then you haven't wheeled it hard enough :)

And he has like 5"" bump stop spacers, so the coil cant be compressed enough to do it either, probably.
 
What?

dont have your hard yakka pants on right now with 18 pockets, for all your excuses ?

:cheers:

You should be able to trim the coils in the rear to manage ride height, maybe not to the mm, but if you trim the dead coils, it wont effect the active part of the spring.

When we started having these coils made back in 2006, we made them to be trimmed, so diesel vs petrol, rear bar/no rear bar, etc can all be bought to the same ride height.
