Outer Limits 4x4 Board

looking for advice on spring rates and shock settings to fit a set of coilovers to a rangie.theres not many running them where i come from (ireland) so any info would be appreciated.also are some of you guys running toyota or nissan shocks on discos
any info appreciated
thanks
JJ

Dont know about the coilovers but a lot of guys with big lifts use toyota and nissan lenght shocks, someone else will know which ones are used where - i have nissan patrol koni's in the front.

I did abit of reasearch on pirate and asked afew questions and for slower rock crawling setups I have just got myself a pair of dual rate coilovers.

The rates i got and will be trialing first up is 400lb over 200lb (dual rate as mentioned) This is for the front.

I am not fitting coil overs to the rear but the reaserch was to run 500 over 200.

I beleive Kermit may have sum info on his dual rate setup for high speed style events and its around 500 over 300 (could be wrong)

PM Kurmit on this forum, he has King coilovers all round on his Rangie, and has been working with Rohan Canavan (7th in OBC 05 with King coilovers) to get it right.

thanks guys for the info so far
king shocks are available to me here
what valve setttings are you using and what length

Dual rate is one of the advantages of coil overs.

You need to determine how much static load (lbs) is carried by each coilover.

And decide how many inches you want the coilover to be compressed at the static ride height (for example 70% of travel). This is how much down travel you will have.

From these numbers you can calculate the 1st spring rate = static load/down travel. This is the combined spring rate of both the upper and lower coils together (note that it is not the sum of both spring rates).

Most people want the spring rate to increase when the coils are compressed a little more than the static load. This point can be adjusted with the nuts that limit the travel of the slider. After the slider is stopped by the nuts, all further compression occurs only in the bottom spring, so this is your 2nd spring rate.

If you plot the spring load against travel you will get a better idea of what will happen.

Eh up Jason, how's things? You done much to tigger since May?

JJ,

What are we doing with a Range Rover??

Those CVs I tried today aint gonna work mate, need to remove too much material.

JJ,
I think Krmit is using 14inch long 220Lbs coilovers on custom hoops.

Mal

Eh up Mal,

How's it hunging? How's the knee/ankle/leg?

Three Peaks was a blast this year, I ended up driving the truck for you mate, had a blast. No worries for next year. Our own event, Muddy Truckers Trophy is on first weekend in March if you're at a loose end. It's only 7 months between that and the Three Peaks, I'm sure we could find you something to do.

All the best for the new year and chrimbo

Check out "post up your rovers" or "how many 90's out there" for pics of the truck

Hey James

Yeah mate knee is healing well very happy with it.

Rebuilding the engine on the truck ATM wll be even quicker also welded plates onto the chassis where it cracked so that is all sorted.Pretty sure this will be my last OBC and am looking for a Navi mate!!! know anyone lol

Have a blast at muddy truckers and sa hello to all the Lads for me

have a great xmas & new year mate

Hi, just a few pix from my pombus.. dual rate springs. is was quite a good setup really. going airbag next time with king dampners.

cheers
