Clunk noise from BC racing coilovers

[BGrade]

I installed a brand new set of BC Racing br series coilovers about 2 weeks ago. Since then I have a clunk in the right rear and now some in the front right as well. I have made sure the spring is seated in the cup in the rear. Added more spring preload all the way around. I’ve but and bolted everything. I can’t figure it out. Anybody have some feedback?

Check your rear swaybar links for the rear. Did you tighten down the adjustable collars on all 4 corners?

I will check the links tomorrow. Yes, I checked and tightened all of the collars.

FYI update, the rear rubber isolators that come with the BC Racing coilovers are a different size. You have to remove the rubber isolator from the rear lower control arms and install the supplied ones. Clunk noise gone.

No the round rubber piece that goes in the rear lower control arm below the spring.

The rear oem strut mount bolts are marked. Mine has blue marks. Make sure they are aligned when you tourqe them to spec.
