Knocking noise on suspension

[Charliessmith]

I have a Seat Cupra 290 MK3 with KW DDC Coilovers, I've recently had SuperPro top mounts and ARB and droplinks fitted and now there is a knocking noise on rebound.
Any ideas what it could be?

What did you torque the coilover top nut top?

Not sure the garage did it, what should it be. I can ask them.

I had a similar issue after having mine lowered. The anti roll bar bolts had come loose. Owner of the garage said they usually recommend people come back for a visual inspection a week or so later but I’ve never heard that before when having a car lowered.
