We've got Whiteline solid droplink kits in stock, not particularly cheap but they do a good job... ... £95 for a pair, i.e. a pair of fronts, or a pair of rears.
Will have to compare them to a price for the standard nissan bits i think. Would i feel much of / any difference with these on a car with coilovers but no other suspension mods?
They do make the function of the ARB MUCH tighter, for example on BMWs stock ARBs with solid links is massively, massively better than the rubbish rubbery stock links.
