Does my car look like it sits kinda high for stock, do you guys think it looks like it has some sort of lift spring in it, like it was on big wheels before? What lowering spring would be recommended, I’ve seen a lot of people running eibachs but they don’t seem to be consistent, some cars are slammed on eibachs and some look perfect. Opinions? Thanks.

Yes, it's definitely high. Probably higher than a stock 9C1, and that was the highest. There are so many choices for springs, I'll some of the Moog experts jump in with suggestions.

Go by the factory service manual numbers.

From the 1996 manual:

The measured FRONT height "spec" (Dimension P on the illustration), through the centerline of the wheel hub of a 9C1 (RPO 7B3 suspension), from the edge of the wheel opening vertically down to the surface the wheel/tire is resting on, regardless of OE tire size, is 28.6" or 726mm.

Stock tire sizes with 7B3 vehicles were 215-75, 225-70, and 235-70 R15.

The same measurement for an Impala SS/WX3 (RPO FE4 suspension) is 27.8" or 706mm.

Stock tire size with FE4 was 255-50 ZR17.

The measured REAR height spec (Dimension R) measured vertically through the centerline of the wheel hub of a 9C1/7B3 vehicle is 28.8" or 732mm.

For the WX3/FE4 rear, at wheel opening, the measurement is 27.3" or 693mm.

You have to remember that the manual specifies:

taking measurements on a validated flat surface

fuel load

spare tire properly mounted in trunk

no other items in car (including people)

tires inflated to door label specs

And, of course, the measurements are based on using the OE tire sizes. Navy Lifer

Ride height stock for 9C1 vs SS

Anyone know where I can find the measurements for a stock ride height on a 9C1 and a SS? I'm considering new springs and don't want to be disappointed. I guess anyone with an SS can measure from the ground to the top of the wheel well and I can compare that with mine. (Depending on tire/wheel...

This is a case where words are better that a thousand pictures.

Yeah, that's not stock SS. The gap looks about right with the smaller diameter wheels on a 9c1. But Z's measurements can confirm. Someone might have gotten 'replacements' from autozone or caprice HD moog replacements in there. Or possibly a clone SS on a 9c1

Thank you for the help, I’m probably going to either find some stock ss springs or go either eibach pro-kit or hotchkis lowering springs. Thanks again.
