Installed stock springs on koni lower perch and somehow car is higher?
#22
As mentioned above, the only things I can imagine that would cause this is if the spring was not properly compressed when the upper mount was installed, or if some goof at the shop failed to thread the spring ends fully into the grooves on the upper mount and lower insulator.
I have stock springs on the lower perch and it was a definite 3/4" drop.

Well i went ahead and fixed the way the springs were aligned and after initially putting it back on the ground the front was extremely high and measured in at 28.5 inches. Drive around a little and it lowered some but its still sitting at 27.5 inches which is what it was at before when the springs weren't aligned right. Hopefully if i drive it around for a little while longer it will drop some more. Ideally it should be between 26.75 and 27 inches if it lowers about 3/4 of an inch

Had something kinda similar. But it was my sway bar causing issues. My links were installed wrong and over TQ. But it was causing my passenger side front to sit high. I'm on Koni SA on the lower perch with stock spring.

Have you replaced anything else, like strut mounts? I'm wondering if Moog parts are a little taller.

I'm having a similar issue except with Str.t shocks (https://ls1tech.com/forums/suspensio...29-75-wtf.html)

It was sitting about 3/4" higher on the passenger side front. I chased everything. Went from Strano's to Factory springs, and the passenger side still sat higher. Last option was the sway bar, and yup that was the issue. Almost a torsion bar effect on the the lower control arm. I did new links and torqued to 18 ft lbs. Now I am 26 1/2" on both fronts, w/ Factory Spring, Koni SA lower perch. I cut one coil out of rear factory spring, install with spring isolator. And the rear measures 27" both side.

in one of the above posts i did mention that i think it could be that the springs are just higher then my stock ones were...unfortunately for me to test out that theory i would have to find another set of stock springs to put on my car. I would use mine however i discovered one of them was actually broken when I removed my stock shocks. So for now just trying to eliminate other things it could possibly be.

Well i went ahead and removed my endlinks and made sure to install them on ramps with the suspension loaded and then drove it around real quick and it still looks to be the same height. Gonna ride around on them for a while to see if somehow they settle more or something and if they dont gonna buy some different springs, will probably try another set of stockers

The top and lower spring mount are molded and have a recessed area that the end of the spring is supposed to sit nicely into. When you tighten the upper nut down and release tension on the spring, the top mount only has one way it's supposed to go to fit in the car, so you adjust the spring to match that upper mount and adjust the lower mount to match the bottom of the spring. It's not that hard but if the shop just put it together and released tension on the spring without paying attention to that, then yes, your car would sit slightly higher.
Any photos of your spring/shock assembly?

Well there's the issue. Aftermarket springs like Moog and TRW are always really tall.

yup that seems to be the trend however i did talk to one person that bought the moog 60114 springs and he said his car is at stock height. I think the 60116 springs they sell are the ones everyone is having issues with but i would rather not risk it which is why i bought some used somewhat low mileage stockers for now.

Point being they weren't stock, which is the impression I got, and I think everyone else. You found your issue.
And it's why I do not sell those springs.

yeah i wouldn't either. I actually contacted moog and told them there are numerous people who used their springs and had issues with the height being drastically off and their reply was just that the factory springs were probably sagging and that their springs are made to factory specs. However as you already know their springs throw the height off by like an inch
