Hi guys,
Got a problem.
Iv changed my rears to koni adjustables and have the soft setting or hard setting now one of the shocks wont lock into place in the hard setting.. it keeps rotating? Is this faulty?
Also i was coming of my drive and this is happening.. Iv got uprated standard ride height springs and this is the faulty shock side

Send it back mate. I would hazzard a guess that the valve inside has become unscrewed which is why it's not holding fluid like it should.
There are little plates inside with holes of various sizes to let more/less fluid through to stiffen/soften the ride which has probably got stuck in the fully opened position

As above, ride height is set by the spring surely. If you take the shocks off the ride height shouldn't change. Do you have a mismatched pair of springs in there? Or a broken spring?
It must be something obvious when you pull it apart.

Nope same springs.. The springs have been custom made as i had this issue with ahmed spec springs.. Ahmed springs use a 13.5mm wire these are 16mm and are 5mm taller than standard height.
Its taken on my driveway so im sure all the weight is on the one side thus causing it to "bog down" but isit supposed to be that bad?

Looks like your springs are too soft - which as the steel bar is thicker would be a surprise.
Is one side much worse than the other or is it just that you have much more travel at each rear corner than you would expect?
I would whip out the springs and go back to the Ahmed ones to compare. Feel free to remove the shocks while you check the springs.
Or you could take a custom spring and an Ahmed spring and put them side by side. Press down with your hands and see how they compare. Is the custom spring supposed to be stiffer than the Ahmed spring?
From the pics you have posted the ride height looks below standard, not higher than standard.
I'm guessing that your custom springs are much too soft and your shocks are fine. New Konis shouldn't fail so I would suspect springs. I assume you haven't driven it on the road yet so you don't know if it squats.
What spring rates did you ask for when you ordered the springs?

I have driven it on the road on the Ahmends and it was squatting and catching the body kit all over, I had the same problem with them when geting out my driveway it was catching the body kit and pretty much wedging the tyre aginst the body. The custom spring is about 7mm taller than the Ahmed one and i was told the ahmed ones were upgraded standard height springs?
The reason im suspecting the shock is because when i compress it ad lock the white button in to make it stiffer its not locking into place as on the passanger side it locks into place and i cant turn it no more but the driver side rotates freely.
Theres no way i can compress the custom spring by hand mate theres very little movment in the ahmed ones.
Im not sure what spring rate mate i took the springs to the suspensions guys and told them my problem they took the measurments and did the rate test etc and just ordered them which should of stoped this issue as the coil is 16mm compared to 13.5mm (ahmed)
Iv also tried some saph AVO rear springs which were 14mm thickness and 10mm taller than the Ahmed ones and still had the exact same issue.

Its not sitting lower on one side mate..Thats on a slanted surface so all the weight is on that rear corner.. My question was should it be doing that to that extent?

if your springs are hard enough, no it shouldn't move to that extent, springs are rated by pundage, ie it takes a certain amount of downward pressure(weight) to compress the spring 1 inch. So driving onto and off your drive at slow speeds it should not move at all.
It sounds like a combination of failed shock and spring issues mate.

ok so you have 3 sets of springs, AVO (reputable manufacturer), Ahmed (reputable manufacturer) and a custom supplier(probably reputable) lol , if all 3 manufacturers result in the same result i say something is really wrong with your car, i would start looking at the trailing arm or turret top to see if there is any damage or deformation.

also check to see if the beam is secure to the chassis as they have a habit of rusting, and are you experiencing a huge amount of rearward beam movement due to the beam moving backwards.
