Car bouncing w/ Stance coils

[240ingthe240er]

Okay, its really kind of tough to explain but I'll do my best.

After installing Stance GR+, I've been having a ton of bouncing under acceleration and braking between 35-55mph in the front of the car. I understand what stiffness feels like from riding in my friend's cars with coilovers. This is nothing like that.

The front end of the car is shaking like crazy and it's very scary. So for the mean time its sitting in the garage.

This is what I've done so far:Increase/Lower StiffnessBalance WheelsRotate WheelsSwap TiresAlignment

What I haven't done:Adjust spring load

Also, the installation instructions that came with the coilovers are terrible and don't include any specs. Is there solid documentation out there to follow? I've tried emailing StanceUSA but never received a response.

My bushings don't look that bad either so I'm 90% sure that's not the issue, though please correct me if I'm wrong.

Anyone know what I can do to fix this problem? Tie rods? Tension rods? FLCA?

If anyone has had a problem like this or knows how to fix this, please help me out! I'd appreciate it very much!

what size wheels and tires are you running?

my stance coilovers did this also for about the first 500 miles. it went away after that, it also helps to put them on the softest setting.

When you adjust the ride height, both side wheels(pass/driver) need to be up. Did you do it that way?
