Hey up Steve , Removed all the bolts gave the centre of the wheel a tap with a rubber mallet to split the wheel cleaned the bolts with wire brush and reused them.
Took the wheels to the wheel refurb garage , but who ever does your wheels make sure they cover the threads on your wheel when sand blasting them and powder coating them. As the garage who did mine did not cover mine so when i got them home to reassemble them the bolts would not screw back in , so i had to re-tap them all which took ages .
when i had done this i did use loctite to make sure they weren't coming lose.
Hope this helps.
cheers Dunk
