car's sitting lower on one corner.why?

Just looking for ideas or things to check.
my r33 gtr is sitting lower on the o/s/r by about 2cm.
I've got tein coilovers which have been on for a good few years which are adjusted to the same height.
I did have them off a month or so ago to remove rust and paint. Fairly sure it was fine after that, but just in case I swapped them over yesterday with no change.
I also removed the sway bar as I had snapped a drop link undoing it and was replacing them but still lower on the one side.
all the arms look straight and the same either side.
when both wheels are off the floor the gap is the same either side.
any ideas at all welcome

Check anti roll bar drop link length.
Undo both ends of anti roll bar and check if car is level.

Check all shocks for gas pressure.
Check all springs.
Loosen all suspension bolts with wheels on ground and re-torque.

thanks for the reply,
I removed the anti roll bar completely and it was still uneven and refitted with new drop links
I've changed the shocks over left for right and still low on same side, fronts seem fine
I've not tried loosen the bolts while on the floor, will give that a go today, not sure i'll be able to with the wheels on, guess could jack up on the lower ball joint to preload?

anyone know the torque for the suspension bolts?
had a search and found 132nm for the upper arms, is that right?

Thanks again

Do your coilovers have height adjustment separate to the spring pre-load?

didn't think they did but a quick search says they do, they're tein super street.
don't think it's the shocks though as I've swapped them over, left for right etc and the same corner is still lower.
Guess I could adjust the one side so it's the same height just doesn't seem right.

Are your coilovers similar to these? Adjustable spring pre-load and adjustable height?

If so you can adjust the height on each corner of the car without upsetting the pre-load.
I have these, and my car was slightly low R/O, about 10mm. Never new why.
Once I'd adjusted each coilover the car was totally level.

mine aren't like that, pre-load and height must be set together, think I read teins site wrong or it's written wrong..

might try and get it up on a ramp at the weekend and try and see what's going on.

thanks for the help
