Just installed the coilovers today and felt the vibration at a stop with foot on the brake, vibration would go away once you release the brake.

WHAT'S UP WITH THAT?

That is what BCR experienced with their initial tests. They said after about a week or so of driving and settling in the vibration went away completely.

CMS,

Did they say what caused the vibration in the first place? I really hope it will eventually go away...

try raising your car up too see if it goes away at a certain hieght. like it been said before some people get it some dont, some feel it and some dont.

so this is happening on the 2is awd aswell? it seems to be an ongoing battle with awd, we are fighting the same battle with the 3gs'.

BCR first had slight vibrations when on the brake in drive. They raised the car slightly, and after about a week of driving it completely went away. Most likely from the suspension settling in.

The problem obviously isn't with the coilovers, but with the design of the stock suspension geometry and axles. It most likely has to do with the angle of the axles in relation to the suspension and the driveline itself. I am not sure if the rear needs to be level, lower, or high than the front to be ideal for the driveline angle.

If you are experiencing slight vibrations I would drive around for 1-3 weeks and see if it goes away after the suspension settles. If that doesn't do it then try raising the car up all around. Then try raising the rear more than the front, or vice-versa. Sometimes when installing aftermarket stuff on a unique vehicle a little trial and error needs to be done.

You also have to remember, aftermarket coilovers will result in a little more NVH. I think a little more noise, road feel, vibration is ok for a nice set of coilovers and a drop. But If you can't deal with a little more NVH and aren't satisfied we will do what we can to make you satisifed.

It def. Doesnt go away. Atleast it didnt for me. We all should agree the reason to get coilovers is to lower and even out the car more than just lowering spring. And of course the damping advantage. So it kinda sucks that you cant really take full advantage of them on AWD by having to lower/raise rear higher than front, or vice versa so the car doesnt vibrate at sitting still in drive. It definitely should be looked into because its not right. And its not worth buying them if they cause this problem.

I have an 06 GS3 AWD.

I can deal with the vibrations at stop. I just can't take the vibrations i get between 10-20 mph during acceleration and deceleration. It drives me crazy during traffic or driving through the neighborhood.

Are IS AWDs getting those type of vibrations?

For the record - I had these issue before the BC Coilovers while dropped on Tanabe DF210s.

Nope, vibrations only at a stop. Once I let go the brake the vibration is gone.

Vibration at stop only when foot is on the brake? Affected by engine rpm, manual/auto, with or not with parking brake?
But not when rolling?
Now that sounds like a real "machine" to me!

Us 350 guys are going to get jealous.

I guess the only good thing about the crappy F sport drop is no vibrations

There has to be some small thing that is being overlooked during installation.

If anyone is near Orlando, FL , or feels like taking a drive, let us know and we can arrange a visit to BCR headquarters.

I wonder if the C connection on the front strut assembly has somthing to do with it... I think you can put them on in either direction and it will go back together. Maybe thats the problem.
