Hi, I have recently purchased a 2019 360S, 8k miles, which has standard suspension at the rear, i.e. no Watts Linkage. I am experiencing a knocking noise coming from somewhere at the rear of my car when driving over bumpy roads. I have checked under the rear to look for witness marks and cannot see anywhere that could be causing the noise. I have secured the brake cables as best I can and secured the wooden boot floor, which I thought could be jumping up when hitting bumps, but I am still getting a knock on the most severe bumps or dips in the road. I have had a few Caterhams' over the years and the suspension on this model does seem a lot softer than I am used to. Has anyone experienced similar issues? Thanks
