Any help would be appreciated
This is not a problem I've had, but the mounts do come loose because the plastic spacers don't seem to lock them well enough to the bulkheads, and the lack of thread engagment in the bulkheads(bolts to short). I have cured the issue (so far)by using the 3 dot mounts (shortest) in the "A" position (lowest).This will lower the roll centre .533mm from the 0mm R/C that the 0B mounts give. I have also replaced the plastic spacers with Bulkhead Shims from the RC12R5 (not my idea all the pro's seem to do this), replaced the 16-12mm BHC's with 18mm sockethead caps (may need 20mm for the rear/rear depending on the the amount of rear TOE IN) and used nylock nuts inside the bulkheads......this really locks the mounts. Two practice days and 2 race days and they have not moved.
The slightly lower R/C seems better.
