Replaced my struts with new Tein coilovers. I don't have a torque wrench but all bolts seem firm. Test drive after installation has a near constant thumping noise from the rear regardless of bumps in the road. I still need wheel alignment so only topped at 15mph. Cluncking after new coilovers appears prevalent but this sounds more like it's hitting something. Maybe the end links?
The dampers have 16 clicks. I adjusted it 5 down from hardest.
