Don't do it!!!
ET35 if for Escorts and Pumas and the like.
You need a MINIMUM of ET42 (so ET42 or higher).......standard Ford alloys are around the ET52 mark to give you an idea, they are tucked right into the arches!
If you fit really low offset wheels then you really run the risk of the catching on teh inner lips of the front AND rear arches and, because of the extra distance between the tyre tread and the hubs, you will probably foul the inner arch liners on full lock, which is an instant MoT failure as well as being bad for tyres and arch liners!
