I have had this car for a little over a year now and have been dealing with suspension noise the whole time. Everything about this car is great but the suspension is louder than the exhaust. The noise is mostly in the rear and sounds like each bump is 5x bigger than it really is. It is like a “clunk clunk” sound over bumps especially at low speed. I have replaced the shocks(Koni orange), the end links, rear sway bar bushing, and strut mounts with almost no help. I am thinking about throwing it on BC Coilovers to help the build and the suspension but don’t wanna drop all that money for no fix. I know this is a common problem on these cars and am wondering what you think it is? I can answer any questions to help solve it. Would love to get this fixed and make the car feel new again!

I'm going to purchase a bobspeed stage 1 engine but I'm wondering what else I should get to go along with this, I'm thinking about a slightly bigger turbo and fmic what other supporting mods should I get? Power goal will be about 450hp

Sound started earlier today. Not sure as to what it would be. Sounds kinda similar to when my timing chain was slapping my valve cover but I had my vvt redone around 10k miles ago.
