Default Installed new struts on front.

Got kyb struts reused springs don't know if it was like this before. But the left side without me in it is lower than the right. I figured the springs are old so order new OEM springs and had them put on. Now the car is even lower on both sides. Got new strut and springs. Same thing. I can't figure it out.

The LS does not sit evenly. The 45# battery makes the left front sit about 1/2-3/4" lower than the right. That skewed weight also has the right rear higher by about the same.

From CelsiorN1 build thread, this post shows a scaled four corner weighting:

Nose heavy, but impressive cross balance. Color me surprised.

3400 pounds for a full sized sedan... cars have gained so much weight in the last 20 years. Though safety equipment does account for a lot of that.

All these years I never knew that. Like I always say, "Even as I get older I learn something new every day". That's how my 94 is sitting now and I thought something was wrong.
Maybe the conversion shocks were actually good on my 93 when I changed over from air. Eh, oh well, whatcha gonna do?

Oh yea, the air suspension kept it level and straight. Just what it's supposed to do, if it's working right. Damn I loved that air suspension, til it broke.

i've stated this in another ride height thread of a person complaining of uneven height especially after a suspension install. i found that most folks forget to load the suspension to normal ride height before fully torquing down the suspension bits. if you tighten the rubber bushings while the car is still in the air, they will add unnecessary tension on the suspension and usually end up with a higher than normal ride height! this could be another factor for the OP.

I wonder if this is the case for Celsiors? since they're RHD and have steering components, pedals, MC and the driver would sit there, maybe adding more weight to the RR corner and balancing out the LF corner

There might be some slight weight differences with the JDM Celsiors. The battery is in the same location on those too. One of the members way back installed a spacer on the shock mount to take up some of the height difference.

I was considering a spacer. What size and where to find one?

He made it from 1/4" 6061-T6 aluminum. I'd just leave it though. More work then necessary to even out the wheel to fender gap. A jig saw and drill are all that is necessary if you want to pursue making them. Aluminum sheet is commonly available in 1/8", 1/4", 3/8" + type increments. The shock mount bolts are typically long enough to accommodate a 1/4" spacer.
