You mean, besides getting the IS350 to begin with right? LOL!

OP, so you are saying that the noise ONLY concurs when hitting a bump? I'd first check for rubbing/tires on the wheel well liner. Next would be tighten up the adjustable collars with the provided spanner wrenches.

GL!

 

Something is Probably loose. Check all bushings, nuts, swaybars, mounts etc.

 

Best decision suspension wise, 2nd runner up is F-Sport Sway bars. They go well together like Chicken and Waffles do (man I can use some right now..).

Back to topic, I haven't had any problems with these coilovers. Try switching the left coilover with the right, try to isolate the problem. If it's a faulty coilover, it will squeek on the opposite side now.

 

everything is fine from the dealer. the sound went away though...so idk what is going on. ill report back if the issue comes back

 

I had a serious issue with my BCR Coils cause the douche installed them wrong...the guy didnt tighten the screw properly and my rear swing arm screw fell out...and id hear that noise like a clunking...make sure all ur screws r there...

 

I hear a rubbing sound in the front of the car when I'm starting to drive around 0-5mph and when I come to a rolling stop without the brakes applied. I don't hear a a rubbing sound when I press on the brakes coming to a stop but when I let off I hear a rubbing/clicking sound. Anyone else have this issue? After 5-10mph the sound goes away or maybe I can't hear it cause getting louder as I drive. I'm not that low on coils and just recently started hearing this noise after I had the radio off.

 

We all can't have those smooth socal roads like you man! haha.

NY roads are harsh. Glad your noise is gone but i would plan snugging everthing up every so often.
