Rebuilding front end+back to stock height=29.75" WTF?
I am in the process of rebuilding my front end and taking the car back to stock height (coming from Stranos). Right now the car is back together minus steering rack and front swaybar connected, but here are the measurements:
FL: 29 3\4
FR: 29
RL: 28 7/8
RR: 28 1/4
Here's all the parts I've used:
Front:
Koni Str.t
ACDELCO 45H0233 springs (marked for 00-02 Camaro SS on Rock Auto)
MOOG K6490 front lower control arm bushings (horizontal and vertical bushings)
MOOG K6689 both upper control arm bushings
MOOG K6462 upper ball joint
MOOG K6145T lower ball joint
MOOG K6517 and MOOG K6516 top strut mounts
MOOG K6573 upper control arm body isolator
MOOG K80927 spring seat (sanded to fit in Str.t perch)
Rear:
Heater hose mod (due to MWC 9")
Koni SA
ACDELCO 45H3025 springs
Stock control arms
MWC poly pahhard bar
BMR panhard relocator
Things I've tried:
-Used GM service manual for disassembly\reassembly and torque specs.
-All LCA bushings and panhard were tightened with the suspension loaded to prevent bind. I even tried loosening the bolts but there was no change.
-I jumped up and down on the front/rear; no change.
-Front springs are indexed in both the lower and upper seat.
-Rotated the RL coil in 90* increments; no change.
-No type of weight savings in front (other than !AIR).
-Stock 275/40/17 tires all around
Honestly if I could get the front close to 28" I'd be happy but damn it looks like the engine is missing! I've been searching on here it it appears there's a connection with Koni Str.t and height issues. I went from Strano+DeCarbons and got exactly 1.25 drop. 2-3 years ago I moved to Strano+Str.t+Moog strut mounts+Moog spring seats, which caused the Strano drop to be cut in half.
Brainstorm time:
-Spring perch on Str.t sit higher than stock?
-Anyone know how high Koni SA's spring perch sits vs Str.t?
-**** Str.t, get SAs with lower perch?
-Moog parts are not to factory specs, taller? Anyone have stock version of K6517 to measure?
-Remove Moog K80927 spring seat and do heater hose mod (seems like a bad idea)
-Drive and allow springs to settle (I highly doubt front will drop 1-2")
-Hire\acquire heavy midget and hide in front bumper?
-Anyone have ideas?

I'm not sure about that as when I added Str.t and Moog strut components my Strano springs drop went from 1.25" to .75". Unless I'm not torquing the shock screw all the way, I torqued it down enough to see the Moog strut mount start to compress. I totally might have installed something wrong however.
There are similar threads about Moog and Str.t components causing ride height issues, here's one:

Just bought Koni SA and complete strut assemblies from a 2002 WS6. My goal is to pop in the strut assembly and see how the car sits. If it sits fine I'll swap the DeCarbons for SAs and see if anything changes. I'll also get measurements on shocks and strut mounts to see how Moog and Str.t compares to OEM.

So I finally got the full stock strut assemblies from 2002 WS6. I half-assed installed them and the front sat about 28". I swapped the DeCarbons for Koni SAs, kept all other stock stuff (spring seat, isolator, ect.), used the SA's top perch and now I have:
FL: 27.25"
FR: 27"
Still need to get an alignment and tires look low on air so those numbers might move a little, however I'm very happy with the outcome! I have some rear WS6 springs on the way too that I'll swap in and see what happens. Hopefully Rock Auto takes back at least the front springs I ordered, because those are horrible!
