So I'm out of ideas on why my ride quality is pure garbage and hoping you guys can help me out...
Here is my setup:
- BR series BC Coilovers (NON true rear) - Dampers set to FULL SOFT
- Swift coilover springs in the fronts at 10k (same rate as the default springs on the coilover kit)
- Hotchkis Front Sway bar
- NO rear sway (have hotchkis installed but currently not connected to one endlink)
- Z1 rear camber arms
- 20mm Z1 hub centric spacers in the rear
- Only lowered enough to eliminate the wheel gaps, but not tucking at all and only had visible negative camber in the rear before my alignment.
I can't imagine the ride quality im experiencing is normal. I've got the dampers set to full soft and im not running stiffer springs than what the kit comes with (10k Front/8k rear on the divorced spring). Spring preload is separate from ride height on this kit, and was installed properly.
Before my alignment I was getting bad darting/tramlining from the rear toe being off pretty bad. As you can see, the camber is still not in spec, but only out of spec by .3 degrees in the rear and .8 degrees in the front. Even with the adjustable camber arms installed, toe can't be dialed in if camber is, and vice versa, so I obviously opted for toe to be in spec for now.
The car doesn't dart around *as much* anymore but I still feel a ton of instability when going over certain bumps at certain speeds. Nothing crazy, just regular street driving.
I know coilovers are naturally stiffer than stock struts, but I'm still feeling a lot of energy transfer into the body of the car and its borderline unbearable.
Before the coilovers, I had swift lowering springs with stock struts and it pretty much felt identical to stock ride quality if not better. I'm about to pull the trigger and just revert back to that setup but I'm still unsure if the there's a different culprit here. Could the amount of negative camber be the entire reason for the instability over most uneven surfaces? If it is, do I just need to get adjustable traction arms to let them get BOTH the rear camber and toe in spec?
The car feels fine when going over forgiving larger bumps, but its the smaller jagged divots and pot hole type imperfections that it absolutely hates.
Here are the final Alignment Specs:
