finally got round to fitting a spax kit to my e30 at the weekend and it immediately blew the top mount out of it housing so it was just sitting up through the boot. Reckoned it might be an age issue so put a new top mount on this morning and the same thing has happened. any ideas? same nearside rear wheels so im guessing it because thats the one running through all the holes in the road but still i made it about 4 miles before the new one blew up 
any help greatly appreciated.

any help greatly appreciated.
