Hey Gav, no worries! I'm with you! I'm looking into doing a lift, and NOW I find out I've got to be concerned with "scrub radius"! :?: :?:
I'm just glad for the willingness of the members of Mud Club to help me become a better educated Land Rover owner.

--- Quote from: "birdy" ---I Put a 2"lift on the old 200 and handling was ok.
Then put qt's on front and back no change to handling.
Then went to a 3" lift no change to handling.
Now running it at 5" rear 4" front handling still ok
as for the panard rod i put a laser light from front to back wheels and they are about 8mm out.
And still running standard front prop!! just got spacers on both.
yet a mate fitted a 2" lift with qt's and the handling was terrible
that bad he took it all off and went for a body lift.
And disco was same year /model. :?:
How can two disco's be so different. :?:

it's all to do with biuld tolerance mate ,ie the way they get thrown together,some are spot on some are well "that looks ok "quality ..hence some can accept 3 degrees alteration and others wont..mine didn't :cry:
Range Rover Blues:
Tyres, wheels particulalry make a difference too. If you change the offset, wheels or spacers then even without a lift the castor angle will be wrong anyway.
I don't get it, Why?
Because the trail (caused by the castor angle) and the scrub radius are balanced to an extent, they go hand in hand.
Now I don't have a mechanical degree so be gentle and use small words mate.
I'll try
I don't understand how spacers (body spacers yes, wheel spacers no)or different off-set wheels can change anything, surely these are acting at right angles to the axle and therefore have no effect?
I can see what you are getting at, the effects os scrub radius would cancel out, LHS/RHS but a larger scrub radius can make the car more twitchy and also alter the self-centring effect when off-centre.
As for bigger/smaller wheels or tyres as you have simply lifted or raised the entire vehicle and not rotated the axle as you would with a lift kit the angle itself has not changed?
True, the angle has not changed, but the amount of trail has, by the same ratio that your tyres are bigger than they were, approx 105 in my case.
I just like to understand what I've done and and what effect it has on the vehicle.
As I often say design is a compramise. The guys who designed the car had a set of values and targets it had to meet.
You have a different set of "wants" from your car to the original marketing guys, so your compramise will be different to the original.
Essentially you only have to please yourself :wink: So if your happy with it then that's 100 customer satisfaction, job done.
As for steering/suspension geometry that's something to discuss over a few beers sometime :wink:
Lyndsey731:
OK, thats the confusion over.
I understand that the trail will increase or decrease and I assume that this is directly proportional to the size of tyre fitted. It was how the castor angle itself would be effected that had me baffled, which we've cleared up.
As for steering suspension geometry, Guinness, extra cold.

Well to make my life easier I'm going to fit, standard height heavy duty springs as the guy in Bearmach says that these will lift the body about 1" and will not require any other modification. I'm not looking to go extreme lifting so this'll do for me, unless you know better and I need to do this and that :shock: :lol: :lol:
Do gas shocks make a difference, I don't do much off roading, mainly going to be the odd greenlane here and there, I was going to get the oil filled armstrongs :?:
