The loss of the OEM rubber isolators would certainly contribute to sending some impact vibration directly into the cabin. I might reinstall the OEM parts in order evaluate how much they contribute to this situation." "I am hoping its the hard point connections because everything else about using TT Shocks on NA springs w/ ST bars feels just the way I want it to feel. The look and stance are just right. Compression and rebound rates of the springs and shocks feel like they are working well together (as they should). The chassis is firm but compliant. The tire's contact patch is always grounded, and there is no skating or skipping around corners under power. Everything seems dialed in except for an occasional initial harsh impact when hitting a pothole or raised roadway edge. Then its a jarring crash before things settle down."
