So.... Went to change the DBM... Found that my existing mount had a rather large crack and chunk missing Plus snapped both bolts into the subframe! Luckily I'd bought new bolts from Sere Motors and GSF had a mount in stock. So some quick work with the grinder had the old one off and I got the new one with the Poly bushes fitted. Old mount after removal. New mount and bush fitted. I would defiantly advise buying replacement bolts before doing this job, both my friends with a Leon had snapped bolts too. Also fitted my quick shift, surprisingly easy to do and feels great!
