I just put VITAVON shock towers on my DBXL-E , and found that there is a big space under the front bulkhead that has been collecting and packing dirt n rocks in there , it was like cement , and was prying up on mounting screws , if you haven't had your bulkhead off recently or at all , it's worth a investigative gander at least , but hey !! Those titanium shock towers don't care at all !
