I just had some bmr lowering springs and koni str shocks installed today. I brought the car home and took it to the store. When I wanted around the car I could see the passanger's rear is lower. I measured the drivers rear and I got 26 7/8 inches. I did the same to the passanger's rear and got 26 inches flat. I measured from the ground to the middle of the wheel well. Do you guys think I got a bad spring? The car was leaned like this before far at I know.

^This. Also double check you have the pigtails of the springs facing the same direction and make sure the top of your spring is seated correctly on the spring isolator up at the top of the springs

 

Just looked at the springs where they mount on the axel and the pig tail on the drivers side ends on the drivers side. The pigtail on the passanger's side ends toward the passanger's side of the car.

 

The very end of the pigtail on both springs should be facing forward (front of car).
Indexing the springs correctly might or might not help with correcting the ride height variation, but this is what GM recommends in their service manual.

 

i will try that, but that could possibly fix almost 1" of difference?

 

Did the car have the lean before? This is a notorious issue among these cars. I would check the isolators as mentioned. The actual reference of the spring to the car does not matter, just the orientation of the spring tail to the isolator does however. Also, chekc to make sure the front is sitting on the isolator correctly. It has a pigtail on the top that must be correctly referenced. I have seen issues like this show up in the rear more than the front due to the difference in spring rates.

 

I have never noticed it before as far as I know the Rea has always been the same height or higher than the front of the car. Now that is lowered the passengers side rear, as I stated is now lower. Is there anything else I should look for and anything that can be done to fix it if it is not what was said. Also will the problem be only that passengers rear spring is not seated correctly?

 

it sounds more like the drivers side spring is not seated correctly and is holding that side up. The passenger side is most likely sitting where it should be. Also, do you still have stock lower control arms? Sometimes after the suspension has been jacked up and such, the bushings will change their orientation and be bound up once the load is re-applied. If this is the case, you can loosen and re-torque the arms with it loaded

 

I did some research and I pulled the spare tire and jack and wow that helped. It is now between 1/4-1/2 inch difference.

 

I have your relocation brackets and non adjustable lower control arms.

 

Ok. Bushing bind shouldn't be an issue. I would still check out that driver's rear isolator and make sure it is seated correctly

 

Thank you guys for the help. I will check it as soon as I can and will update the thread. The car handles and takes off so much better than factory!!!

 

Did you have an adjustable pan hard bar installed as well? If not then maybe that would help a bit

 

Yes I do have an adjustable pan hard bar.
