Shock absorbers Bilstein or OLD MAN EMU

Yes B4's should help.

Drader has swapped for B6s in the rear of his Alltrack so has 1st hand experience with it's effects.

I went with B6 rear shocks and slightly bigger RSB. Was super happy with the balance until I added air bags (Air Lift) in the rear. They are great when the car is loaded with camping gear & bikes (prevents sagging but), but when empty, the handling is pretty unbalanced between front and rear (even when AirLift bags are at their minimum PSI).

I believe Bilstein has a B4 version that will fit front and back and also a B6 rear inset. Probably the best option for OP. Rebound damping on stock shocks is the biggest issue.

Took a few trips to the dealer but finally got it sorted under warranty. First they changed the rear end links. Then replaced the front shocks, bearings, mounts, and end links. OEM shocks failed on Boston roads at 25-30k miles. If you are out of warranty, consider replacing with Bilsteins.

New Bilstein Rear Shocks

Love the B8s! Great combo with the lowering springs

If you can swing it, you're better off with new springs and shocks (Old Man Emu kit, or OME springs with Bilstein 5100 shocks), even if you have to save up.

I've had the chance to daily Billstein shocks w/Eibach springs...with stock shocks w/HR drop springs...The Bill and KW setups had/have Meyle HD front bushings and R32 control arm bushings.

My car is out of alignment too (neuspeed sport springs/bilstein shocks/17" rims). From what I am told, after having the car aligned 3 times, the only way I can get it back into alignment is to reinstall the stock springs / shocks.
