Uneven ride height

I was just reading the thread about Koni's on FD's and I remember reading last summer about how FD's are known to sit low on the driver's front side.

When I installed the Koni sport shocks and Eibach springs (from Pettit)
I did notice that when sitting level the gap between the fender and the top of the tire was greater on the passenger side then the drivers side. It was a clear difference! I even called Koni but they said that my install was correct.

I have since put on 17" and moved all the lower perch mounting locations to the middle position and had an alignment. I still notice a difference but not as much.

Can anyone confirm if this height difference is a fact of the car's geometry or special cases of suspension wear.

Just wondering...

I have the same problem.
Installed H&R lowering springs on my 93.
My rears are even, left to right, but my
left front is 1/2 " lower than the RF.
I switched all the mounting rubbers
from left to right (except springs) and
it's the same. It has to be a variation
in the springs.

I've done the same thing (except brand new rubber pillow ball mounts and rubber sheets) with same springs, with the same resulting problem. Only way around this design quirk is ride-height adjustable coil-overs.

I've got the Koni's on their full drop, and mine is and was the same way before the struts... about 1/4" to 1/2" lower on driver side... I was told it's not a big deal, that many cars vary about that much. That, or we're all getting fat!

I've noticed the difference too on my totally stock, low mileage '95. It's not a problem as the car feels perfectly balanced, and the difference isn't noticeable visually, only when you measure it.

Here's a theory, and it's only a shot in the dark, but do you think the difference has anything to do with the car being designed in Japan? Could the designers have set it up to ride a little higher on our passenger side because in Japan that side carries the driver and the extra weight of the steering column and some other things? Like I say, it's only a theory.
