Lift if you want to fit tyres bigger than 33 inch,
I have fitted Red/White RRC HD springs all aorund on my 90 its technically a 3 inch taller springs than std 90 however as the springs are a softer rate 175lbs inch opposed to 215lbs an inch fitted to a std defender setup it actually settles about 1.5- 1 inch higher. REMEMBER these springs are softer and all the same height whereas std 90 or any other LR springs are all different heights in each corner. Fitting a kift "kit" is never good because a cheap one is not actually a comprehensive kit and will affect handling etc. I use std shocks at £12 each you can't go wrong my rears have been fitted for 3 years no problems. I have driven 90's 110's discos and RRC and they all handle that bit horrible when lifted. If you just rebush every suspension link, fit new trac rod ends the A frame balljoint aswell as LR intended you will have yourself a very nice handling LR fart superior to 99% of the lifted landys out there. Most old ****ters or old buses handle ****e before a lift kit because they are worn out and feels sloppy fitting a lift kit tightens it up but if it was sorted before hand then the difference is more than noticable.
Offroad Red/Whites were the triallers choice for may years as they are very cheap softer and longer (Like Andrex). now days terrifirma and others make rated springs for motors and have taken president however at performance vs cost red whites are just fine. If you intend on carring any weight look at std springs or indeed HD springs (find out exactly the Lbs per inch before parting with any cash). Be careful how the "lift" is achieved and pay particular attention (if looking at kits) to articulation people pay alot of money for atriculation. However save the dosh and buy a axle locker and you will get as far as these guys with show suspension droop if you can drive half decent. P.s If you get into it join an offroad club thats associated with Association of land rover owners. No bull****e no bling tricked up tat just stuff that works tried and tested.
Buy a Rope not a strop! come back in 10 years and tell noobies the rightous path. Avoid noobies becoming the lifting strop donning, wrecked discovery driving a pay and play hack shouting about how great a lift kit is that cost him £400 quid spinning up diff centres while stuick in a wee puddle blowing them apart with noo chunky tyres. You will then understand that a £350 difflock in the rear and std height /red/whites setup will be just fine driving around past these pretend "extreme" wannabes. Sitting in your warm comfortble defender driving past while the muppets are dragging half a rotten disco out of the mire! screaming that the diffs are weak and that his snorkle fell off and now his engine os fooked again. You can sit back and enjoy because some of us that know and have seen people come and go over many years are here offering you advice to help you avoid falling into that dark place.
Happy Xmas!
