Outer Limits 4x4 Board

we have some dobbins coilovers (old type with 5 way adjustment) measuring....between coil retainers (with the adjuster nut right to the bottom of the shock)

extended....710mm
compressed......375mm

as far as we can work out the rear of the zook weighs between 130kgs
and 160kgs.

does anyone know how to work out the spring rate ? eg length, no of coils
, diameter of coils.

and who can make em soonish?

the zook barely drives on the road, most is trial and rock.

it also has no slider, so just a single spring.

Hey there Mark,
I don't have any personal experience with these but I believe the place to have them made is kings (which is on the Gold Coast) and they can do the math for you. However I don't know if they deal direct with the public

yep will try them tomorrow....

its not a prob asd im not public.. i deal with em a fair bit..

but usually it takes em 3 weeks to make em... and ive got just under 2 till i need the zook going

Sorry to take it off topic, but what's in 2 weeks? Is there something I don't know about

lcmp hill climb...

im not in it but going there for a mates b-day and also for the zooks shakedown run so that it is ready for the logan challange.

the back of my lux weighs around 850kg (weight on rear wheels) and i have 200LB springs. works well could be a little softer. Im not sure on the maths to work it out. my spring rate may help!
