Ok, I need your assessments on the situation. I had previously asked in a thread about why my right rear was so much taller than the left.

Some suggested that it was due to my car having 62k miles and with typically only one person that the springs were worn on the driver's side. Makes sense.

So, per advice, I installed a lowering kit on the right side. I lowered the new rear bolt almost to the very bottom. The car then sat pretty even, with the left side still being about 3/8" lower. Not enough to bother me really.

I noticed today that the right side is back up to about where it was previously, maybe a little more than an inch higher than the left. What could be the cause of this? Should I replace the shocks? Could they have anything to do with it? Or should I replace the springs?

Come on Vette-heads, there's a lot of know how on this forum, help a guy out.

Also, with the the right side extended bolt almost to the stop, should that have lowered it substantially? The top of the tire is 3" for the fender arch. 3" my not sound like much, but it looks it to me.

Update, I had noticed this after arriving home. I just went out to messure again and the left side has settled a bit and there is now a 1/2" difference in the two sides. Is this due to the shocks?

 

i think its indeed due to the schocks !

 

raise the low side and keep the high side dropped! if that is not enough , buy new shocks!

 

Not sure if this helps but check the condition and tightness of the bushings and control arms.
A performance shop I was used to work at did a lot of suspension upgrades on cars and a new mechanic had just got done installing a complete moton suspension on a porsche. When we went to sit the car back on the ground it was considerably higher than factory. After messing with it for several hours we figured out he had tightened the suspension while the car was raised and therefore putting pre-load on the bushings and not allowing everything to move properly.

 

It;s not the shocks, it's the fiberglass springs, they rebound differently depending on how long the load is off. I've had my car up in the air a lot this year and I noticed everytime I jacked it up for a few days and put it back down, it settled in a different level even when I didn't touch the suspension. In the past, I kept lowering the rear on the bolt but the body just kept going up. Eventually it will settle down but it seems to take several months. I took half an inch out of the bolt and spacers 6 months ago and the rear is still slightly higher than it was before I took the space out.
