Default Slight Vibration at idle after BC Coil install
My car is getting a slight vibration when its in Reverse or Drive now.

Also im getting a bit of it in the pedal from 0-20s.

I tried searching and didnt find much info.

Read somewhere that it is related to the front diff?

Mine's like that, not sure if its normal but its definitely common. Plus the slight wobble between 10-20mph is common.

Alignment shouldnt be an issue since we didnt touch anything related to it.

We didnt even remove the C clamp for the front shocks. Just unbolted it so it could slide over and used a flex socket to zip off the bolt for the shock.


I do plan on getting an alignment check in a month or so when everything has settled down.

Probably from the use of the top plates since there metal with no sort of rubber bushing like the stock units. This will help with road feedback but you probably will feel more vibration because of this.

Alignment should not have anything to do with this but you do need to get it aligned asap since i'm sure your toe and camber are off.

Alignment is always an issue when lowering a car. Whenever you touch the coils to raise or lower, you have to get an alignment. Camber and Toe will be changed from lowering it.

What are you tweaking? Did you find the root of the problem?

Ill prolly be the first one to buy the fix lol.

I dont notice it with the bass in my car but its a problem that needs to be fixed.
