I treated the edition 30 to an anti lift kit, unfortunately my repayment was in the form of a snapped bolt. Brilliant.
Nearly been there. They are steel (one use stretch bolts) in alloy and the bolt end thread protrudes though the top of the subframe. So it’s a great idea to clean that bit of the thread off with a wire brush and a bit off WD40 before even attempting them. If they pick up on the thread and start to go tighter don’t force them, back off 1/4 turn and then try 1/2 turn, repeat.
I took 45 mins to get 1 bolt out and another half hour for another. 1 wasn’t playing ball so I wound it back in and replaced just the bush in situ. All of this doesn’t help you but maybe will someone reviewing this thread in the future.
Knowing how tight that would have been to cause the bolt to snap, it’s not coming out easily. Maybe you could get a bolt welded to the protruding end above the subframe and wind it through the other way? Good luck and please let us know your solution.
