Lucky 8’s Project P38

Can you do center of the wheel? Please

 

[R-Overland]

Mine measures 23" front and rear to the center of the wheel.
The standard ride height is 19.25-19.5"
This is the accepted measurement from wheel center to fender lip.

 

[Fivespddisco]

Thank you sir. Were did you find that official measurement of 19.5?

 

[R-Overland]

some wise guy gave me a speech about the proper ride height once.
I thought , what a prick... normal height fluctuates by only a quarter inch?
it kind of stuck with me

The ride is good. The springs are linear.

What did you want to see in the picture?

I had same idea, progressive springs front and rear.
But everyone discouraged me, that will ride very hard, will lose good articulation of Land Rover.
Photos, when show installation of arches, then you will see spring. I soon I did this exercise with installation of arches.

........ it nice project, share more photos if it.:beer:

I can't measure mine as my ride height is no longer stock and I do not have calibration blocks to get the suspension exactly back to OEM specs.

Paradigm, are you sure on those 19"? This actually sounds a bit high for OEM standard ride height - it sounds closer to OEM off road height.

The stock tires are 29" in diameter - so half of that (center wheel) would be 14.5". The height measured from the ground to the arch is 790mm=31.1". So OEM standard ride height should be somewhere around 31.1"-14.5"=16.6" center wheel to body. 19" even sounds a bit high for off road height (40mm over standard in OEM settings or 1.6").

I'm sure these measurments are posted somewhere on Rangerovers.net...

 

[R-Overland]

Like I said, I didn't measure it myself and since I always had springs, had no way to confirm or disconfirm that statement.

OK, did some more quick checking:
"According to Atlantic British, the height of a P38 in standard ride height with stock tires measured from the ground to the top of the wheel well is 31-3/4” in the front, and 32” in the rear."

The values I gave above are from http://www.landywiki.co.uk/index.php?title=P38A_Suspension but do not take into account the difference between front and rear (5mm according to LR)

The official method of calibrating the P38 EAS involves removing the bump stops and inserting calibration blocks which are 100mm for the front and 105mm for the rear. So the best method of determining how much lift you have is to measure the distance between the bump stop mount and the axle pad and compare.

I found a set of blocks. Now I just need to get my hands on them.

 

[Fivespddisco]

One of my dealer friends just went out and measured a truck on the lot and this is what he had.
17.5 front
18 rear

 

[R-Overland]

so that narrows it down a lot... the measurement should be a figure between 15 and 21" simple as that.

 

[Fivespddisco]

I should be able to get the blocks tomorrow and hopefully put an end of this early next week

I wander if ill have any issues putting those nitto's on my stock 18s

order my springs today from lucky 8 ready to get started .....sure wish i could get one of the luck 8 decals for my rig so i can represent LOL:wings:
