I had the tech at Dyno Comp check the coilovers twice in the same day. I remember when we had the wheels off there a 2-3 mm gap between the bushing and the sway bar. The tech took it off , greased them, and reinstalled and the knocking actually got a little worse. I think its because to remove the bushing you can to bend it open to get it off. So I think the tech inadvertently increased the gap between the bar and the bushing. I am hoping a set of new bushing will take of it. I will go back to stock bars if needed. I want the car to be perfect. I don't want to "live with it". I demand perfection

I took it to the dealership today and they said they are going to order some new F Sport sway bar bushings and said they will insulate them when they install them

hey guys just wanted to post on the noise fix. I took it to the dealer for a check and they found that the sway bar bushing was the culprit of the knocking. They ordered 2 new sway bar bushings and they said that the rattle has completely disappeared. My service rep said that the new sway bar pushing have exactly the same dimension as the original ones that came with the sway bars but he states that they feel much softer. He said the old ones were very hard.

I just wanted to post that the knock was 100% the sway bars. I picked up my car and drove it a bit and have found that the new bushings resolved the issue 100%. I wanted to make sure that all who saw this would still feel that Tein products are solid and well built. It wasn't the coilovers. Just the F sport sway bars
