My Olds is sitting like really high in the back. I figured out, that it has moog springs installed that sit about 1" higher than original Delta88 springs. I want to replace them and might consider choosing a spring that even sits lower than original ride height. Found several moog springs that would fit, but which one would give me a lower ride height (1-1,5" drop)?

 

I moved your post to a new thread. Hopefully you will get more replies. Here's a good thread you should read:

@ Olds64: Thanks! Did not want to create a new thread so I just posted into a existing.



Some more questions that could help me what to buy:

Who has moog springs mounted in an 80s Delta88? (or other box B-Body?)
Which Moog Part No?
What ride height did it result in? / What is the distance hub to fender?


From the Impala Forum I learned that it should be easy to calculate ride height if you have:
Unsprung masses of an 80s Olds Delta88 for each axle/ (or sprung masses and total curb weight)
+ Spring rate and free height of a original Olds spring (or at least one comparable).

Then you would have all needed data on the Moog website to choose exactly the spring for your desired ride height and comfort level. I even created a small excel sheet to help with calculation.

Just to let you know why all this trouble: As I live in germany moog springs are the easiest to get shipped overseas. Also I'd rather do it right the first time cause I guess you can imagine shipping and taxes dies make ordering parts quite expensive :-/

 

I updated the thread title per the OP's request.

Be aware that any new springs you get will raise the ride height unless you specifically get lowering springs (or cut a coil off of the OE springs). Good luck in your search.

 

Cutting springs is not an option for me.

And yes, thats why I would data from people that have Moog springs installed ind their Delta88s. With this data it would be easy to calculate the "real" ride high based on spring rate and spring height. Or at least an pretty good estimation. In another forum someone created a chart for this and I would like to adapt it for the Delta88.

Those values are currently not correct, but it should look like this in the end:



By this you could choose the correct spring for the desired ride height.
