		The theory is not the same as the real world in LR's case.
 I run 2 Red/Red OR 2 Red/Green, a mix of both causes the lean.
The Red/Red increases the vehicle lift by about 10mm. 
Currently I have a pair of red/green, sits level and is a good height :)

		By the kings website KRRS-02 is front and KLRS-04 is rear standard height springs for a 1985 110 county station wagon with load leveler.
Shopping around, the KRRS-02 is easy to find, it's the same as the rear spring on range rover classic 150lb/in.
KLRS-04, not so easy, as of today when I called king springs, KLRS-04 for county rear with load leveler is no longer produced... He said 220lb/in spring rate on these and they have nothing similar.
KLRS-05 which is for models without load leveler, is 470lb/in he says.
They do still sell KLRR-05 which is the 470 spring rate, but raised.
Side note: OEM spec is 330lb/in for NRC6389 and NRC6904 (this would explain getting a bumpy ride changing from OEM to kings rears)
Fortunately NRC6389 and NRC7000 are available from the usual land rover suppliers and show 180lb/in spring rate, which is a lot less than that 470, so hopefully my 110 rides like a range rover ha ha. [biggrin]
I did check dobinsons and lovells catalogs, same deal, no one here makes the standard height rear coil in softie spec.
Maybe I will quickly find out why [bighmmm]

		150lb in the front is pretty light. Assuming it's a V8 With no bullbar etc????
I run kings front, dobo rear. 210lb front, 318lb rear, isuzu, f&r bars etc..about 30-40mm lift though

		Good point, I just took that 150 from red90 website.
I'm not certain which RRC coil is used in 110 front, do you know which one was used here?
I got info from Kings today, KRRS-02 is a 230lb/in spring rate, free height l/h 405mm r/h 415mm
