Default G/C Koni Setup EF9, Rear sitting uneven, what to do.

Car: 1991 Civic Si Hatchback
suspension: Ground Control Koni Yellow's with off the shelf spring rates
Wheels: 14x7 +27 Front +32 Rear

So here's the situation..
I recently adjusted the height of all four corners of the car because the front was rubbing on to the fenders and the rear was just too high up. After raising the car in the front (by adjusting the collar on each perch on the front two corners) and putting the car back down the car sits even in the front with equal gaps between the tire and the fender. HOWEVER when I had adjusted the back two corners EVENLY and put the car back down, I found that the right rear was perfect, where I wanted it , with about 1.5 CM gap.. BUT the left rear was tucking and the tire was very close to the fender, enough to rub going over any bump...


What is causing this unevenness? I know it could be chassis flex because this car 21 years old, or I've read somewhere that maybe the alignment is off causing the illusion that it's tucked on one side and a 1 1/2 cm gap on the other...

What should I do? Can I just raise the left side more than I have the right so that the car will appear to have equal gaps on both sides? If alignment will fix this I worry that if I raise the left rear more than the right rear to compensate then after alignment is done my car will be off again?

either how I need help..

Cliffs: height adjustable G/C Koni Setup, rear left and rear right adjustments made on the collar/perch are identical but car sits uneven in rear. Should I raise left side to compensate? I want to get alignment but I really want to have the perfect ride height before I go and get it so I won't have to make adjustments after the alignment....

You're making it harder than you need to. Adjust each corner as needed.

adjust the perches to get equal gap, just because they're sitting in the same position doesn't mean your car will...

easy peasy lemon squeezy

but why is that? when the stock suspension is on there its not like the spring lengths are different to compensate for gaps... if everything is sitting in the same position shouldn't the car? minus chasis flex minus alignment issues minus possible incorrect install of said suspension
