I think I used vice grips and another person to undo the top mounts. Much easier with a second set of hands. Also used a really good 7mm Allen key - its about 200mm long with a nice grippy handle
Keep at it. It will move!!

On another note my KW v1 coilovers rocked up yesterday. Gonna see what happens with my wheel plans before fitting.
Question about wheels. If I have 18's will I not need to lower it much as I would have to with 17's to achieve a decent stance? Et31 up front and et 21 in the rear with 7.5" if all goes to plan
