--- Quote from: "davidlandy" ---there are different rates - my OMEs are d44 spec and I have had no probs, and tbh you dont hear of many, if any, issues with them either.
I have seen many yellow and blue springs that are rock hard and dislocate all to easy when some other springs would expand a bit more.
if u do go for britpart then be sure to fit re/dislocation cones as well.

Going by the data on both springs on discoparts web sight
http://www.discoparts.com/files/old_man_emu_spring_application.htm
and
http://www.discoparts.com/asp/products.asp?CatID=8&SubCatID=52
(click on the individal britpart spring for its spec)
Then:
OME761 and DA4201 are near enough the same spec
OME751 and DA4202 are near enough the same spec
OME764 and DA4203 are near enough the same spec
OME762 and DA4204 are near enough the same spec
OME763 and DA4205 are near enough the same spec
OME754 and DA4208 are near enough the same spec
Not sure what spec OME springs d44 supply, but it would appear all the britpart lift springs are based on OME springs.
As far as i'm concerned they are all a bit short and stiff but then I don't have to deal with the weight of a fully equiped challange truck.

Another recommendation for the Gwyn Lewis set-up. You can buy it all online plus brake hoses at http://www.llama4x4.co.uk/
Front kit including shocks, +2" turrets, cones and spring retainers is £149.90
Rear including shocks, +2" mounts, relocators and spring retainers is £197.90
You won't need extended bump stops
I think the negative views on Britpart springs are mostly hearsay, personally they've worked fine for me on a couple of different vehicles. Going by peoples reports, the bearmach ones seem fine too. OME are good, but are 2x the price and the D44 Challenge Springs are £300 for a set of four delivered. They are well specified giving a level 2" lift with long travel and I would guess that they are in the 190-200lb/" rating. They work really well off and on road but are an expensive option.
Do you need a 2" lift? Consider a 1" or 1.5" lift. With a 2" lift you do you risk front prop vibrations/wear and steering will be slightly less precise. Both a 1" or 1.5" lift will be fine with 33" tyres.
I would fit cranked rear trailing arms to get full benefit of articultaion. There is no drawback to doing this that I am aware of.
After messing around with various set-ups I ended up selecting some standard LR springs to give me a ~1" lift all round with 33.5" tyres ....
The springs I'm using are..
* NRC9448 Blue/Red 15.31" 225 lbs/inch on rear
* NRC9449 Yellow/White 14.80" 225 lbs/inch on front (winch bumper and ep9)
On the rear I'm using X-Eng's X-Springs instead of relocators and these work extremely well at giving extra articulation and traction. To fit these I turned the spring cups round and fitted RR rubber isolators to top of spring.
Just need to move the TD5 fuel filter forward by a couple of inches, so that I can finish it off and fit the rear Gwyn Lewis mounts and the rear Rough Country shocks.
Hope this helps

Yeah special tracks are much better offroad, not really the same sort of tyre. KLs are a quality tyre with compromise for off and on road where as ITST are aggressive remould, cheap but designed to work well offroad. KLs may perform better on rock though and the increased size is a benefit.
Have front challenge kit bought from Llama on my bobtail, its good stuff and well priced.
Bear in mind when looking at springs that standard 90 is 175lbs front and 225lbs rear.
There is a lot of stuff been said about this in the past so you might want to try doing a search.
