A question for PJB perhaps. The Mulfab steering roller bearing conversion and spring set comes with different springs dependent on the model (90 lb for 4/4 I think, heavier for +8 etc) which seemed logical. Does the Suplex kit come with just the one type of spring for all cars, in which case does the ride quality vary between light and heavy cars, or is that dealt with by the ridd height adjuster? Also the dampers are presumably just one "strength"? If I am displaying my ignorance, apologies. I am thinking of having this fitted soon to my 2005 4/4. Nigel
