Uneven Ride Height

[shyr33]

Hey guys

I'm a little stumped on how this happened so I though I'd get some suggestions. I did a search and found differing ride heights on other skylines but mainly due to old springs sagging.

I recently fitted some new (second hand shocks) and new TEIN S.TECH springs on the car and everything was fine. It lowered the car about 20mm ( the maximum rated is Front:32mm, Rear 30mm drop). I measured the heights at the fronts and they were the same and both rear heights were the same as each other.

Whereas now about 2-3 weeks after I measured the ride heights (measuring from centre of wheel to guard) and I get these

Front Left: 355mm

Front Right (drivers side): 348mm

Right Rear: 353mm

Left Rear: 348mm

Now these might be 1 or 2 mm out, but you get the idea . The front left and right rear are a bit higher than the others (and yes the concrete was flat). And considering when I measured them after the install they were fine.

The only thing I can think of was I gave the car to PEDDERS and they did a wheel alignment and put some pineapples in the rear. Now I don't think that could change the ride height could it?

Thanks in advance

Just different weight distribution matey,

Only way to get it perfect is with adjustable suspension and corner scales.

It's not that bigger deal anyway and not noticable. What do you think happens when you get in the car?

did u fit these springs yourself?

due to the camber of the road the driver side of the car should sit a little lower then the passenger side

so u may have the rear springs in the wrong sides

really? i'm not going to straight out call bullshit, but i have my suspicions..

not all roads have a large enough crossfall to warrant jacking every car up on the right hand side

[jaypea]

its definitely not bullshit, hardly call a few millimetres difference as being 'jacked up'

common trap for people installing lowered springs, need to remember shorter ones always go in the drivers side

Hey guys, thanks for the replies

Ye I did put them in myself, but from memory I couldn't remember seeing anything on the rear springs indicating a Left or Right side. And looking at the two they didnt seem different lengths, but I guess a few mm is hard to see.

I know that the front drivers side sometimes gets a little bit lower over time due to the weight of the driver but its just strange that it was fine for like 2 weeks and then now it becomes all uneven. Unfortunately I have damper adjustable shocks but not height!

So does anyone else have any ideas? Or did it just take a while for the suspension to adjust to the different weight distribution on the car?

You might have a bit of pre-load on the sway bars. Try disconnecting one link on each of front and rear bars, and re-measure the ride heights.
