ive just won some brand new bearmach 2" lift springs for me disco
now the qs is it says the rears are 207llB and the fronts are 149llb

i think they may be medium duty but now sure how the poundage thing works

my disco has been bobtailed and the front has winch bumper and an 8274

anyone know about they springs and how the poundage ratings work? ta

2" springs wont beat the height of mine naaa naaanee naa naaa :D:D
 
id probably put the backs on the front and visa versa, as the poundage rating is the pressure it takes to compress 1 inch and so the higher poundage rating on the front would help support the winch and bumper ect and make for a leveler ride as if you have the softs on the front with all that weight you will more than likely have no lift at the front :)

makes sense:) gonna fit them and see what it looks like
 
the heavier poundage springs will be noticeably stiffer to compress.

does garage man pete have a hydraulic press with a gauge?. whack them on there and measure deflection.

dont be a nancy put one of each and lean on it which ever compresses easierst is the lighter duty ones.

I run 175Lbs/inch all round + 3 inch FREEHEIGHT and the fronts is about right with a winch heavy bumper and tdi (Note heavy engine) and the back is ok bit soft if loaded up. On a disco Std disco with the overhang the back body is heavy especially if you carry any gear in the back. I think the light duty ones will be too light for the rear and the lightger duty ones maybe too soft for the front.

Try them and then go and buy a 4x RRC Rear HD Red/whites all round about £60 for the full set
 
then tyr the lighter ones on the back but the front unless you have several girders attached to the front end I think you will notice you will find it quite hard to compress and may lift the other wheel off the ground earlier than a softer spring would aka your originals and before it fully compresses. Personally I would love a set of 4 of the 149lbs/inch plus 2 ride heights (your lower ones) for a trials vehicle as they are quite soft and tall for a soft spring

there is a big winch bumper and 8274 up front
large fuel tank is mounted behind seats so aint really front or rear for the weight to be taken into consideration
 
I did this for a friend not long back to work out the cornerweights on his class 10 autograss.
Get a 20 ltr plastic barrel and fill with precisely 20 ltr of water. Measure the height of the spring before and after applying the weight. This then gives you the change in spring height for a given weight. Use a bit of maths by divdibg the change in height by 20. This gives you a spring height in kg/mm. Easy to convrt to lb/"
 
From the above you can apply a similar principal to your present springs whilst they are still fittedcto the vehicle to determine what actual spring weight you want for your vehicle. It helps if you have a fat mate to act as the pre determined applied mass.
 
Logic says the heavier duty ones on the front. But, as always its probably not that straight forward.

I know when i did my 2" lift with bearmach HD springs it was a really hard ride. As soon as i changed to +2" OME non HD springs the height stayed but the smoothness was much better.

If it was me, i would do the maths as your bobtail isnt exactly something that you can guess with is it?
