Springs and shocks

I want to replace the springs and shocks on my Series 3, but can't decide what to go for. It's mainly used for greenlaning, and I'd like to have a go at an RTV next year.
Would parabolics and extended shocks, such as procomps be best. Or would normal springs and shocks be good enough?

do not buy britpart stuff,been there done that had the refunds
try here
Leaf Springs from GME Springs UK
or here
Jones Springs Ltd - Repairs I Resets I Replacements

I looked at a few options, either "british springs" direct from the factory or the rocky mountain options, i put british springs on, i think the rocky are a little softer, think i would choose them 2nd time round but the British are ok and either is better than the original

Got to aggree with Mr Dripper. I too have been there and had the refund on the Britpart paras. Never before have I seen such a bag of w*nk! Now got Rockys . You will get a ride close to a coil sprung landy with paras fitted rather that the standard "oooow owwwww oooooooow! have I got any suspension on this thing?" Its nice to keep em standard but Its also nice to have teeth in your head after green laning. Makes It a more enjoyable beast to drive but im sure that theres people on here that swear by leafers rather than swear at em. Its all down to personal preference.... I choose to keep my teeth

hi
i have had good results using std hd springgs on the front and green or blue parabolics (ex paddocks) on the rear. better ride , but corners flatter on the road. yes and every time i do it they say you should not mix the two types.
works for me and they sit well on the road.
