Had local shop install new IAP red springs and Koni red shocks all the way around. Shocks rear full soft and front ¼ turn hard. Also a new tyranny mount bushing with poly upgrade. Replaced rubber bushings (2) and bearings (4) on rear sway bar. Left in both factory Aluminum spring spacers’ front and rear. Below are measured at the center of the fender well.

Before:
25” | 4-3/4” | 25”

24” | | 24-3/4”

After:
24-1/4 | 4” | 24-1/4”

23” | | 23-1/4”

So after the install front is DOWN ~3/4” and the rear is also DOWN (?) anywhere from 1” to 1-1/2”. The rear before the install already had a bad ¾” lean to the driver’s side. The front sump guard is now only 4” off the ground. In the photos the front is clearly HIGH and the rear is too LOW (?).
1) What would cause the rear lean to the drivers side?
2) The front came DOWN as expected but now looks like its too high.
3) I expected the rear to rise a bit but it is clearly riding too LOW.
Before and after photos:

Has the trim been reset with ballast in the car and shims put to use? (what it looks like when sitting with no~one in it is meaningless)

Conversely, if shims were present with the old stuff, did you just pop them back in right where they were without consideration for the potential changes that new springs might create? (the old shims were for the old springs with thier old, probably original, trim setting so they aren't neccisarily going to be right with new springs of different rate and height)

Did you get the proper front spring pan on the correct side? (the deeper one goes on the passenger side)

Did the rubber end cones on the old rear springs find there way onto the new springs?

Were you aware ahead of time that the performance springs are meant to lower the ride height? (some of the handling changes comes from the whole chassis being lower to the ground in general and the weight shift involved with getting the rear lower than the front along with that also has an effect)

'Course it looks like you're parked on a grade too, which might cause things to seem like they're leaning backwards or forwards depending on which way the car is pointed.

My S4 kind of looked like it was sagging in the rear left. I had new springs put on it. It still kind of looks like it's sagging in the rear left. Maybe it's a fuel tank thing, I dunno.

Almost everyone here who's tried the yellow poly insert for the transmission bushing has ended up removing it due to nasty vibrations, BTW. It appears to be one location where stock is better.

Yup.
Still good to use the fat washers that come with the poly kit though as they do a much better job of keeping the tail of the trans on center and give a bit of anti~torsional support to compared to the cheese~o~matic uber thin stock washers that go there.

The front coming down evenly 3/4" should be just fine, even with the sump guard 4" above the ground. That said, you are going to need to make some adjustments with shims to the rear. That is not unusual, and there is no reason why you (or the shop) will not be able to get the car leveled. If you need shims they are available from the usual suppliers.

Best regards,
