Only 20mm wide and is going to look subtle like OEM.

Why only 20mm??? Well here's an explanation from the GT4OC.
"There are several major benefits to this, for many people the main benefit would be fatter looks - but thats not the only thing. In stock form the rear arches have space to take much wider or bigger offset wheels than the fronts, with a 4wd system you really want to run the same width wheels all round so most people resort to running spacers on the rear to make it look better with the deep rear arches. The problem with this is that the rear track width is deliberately narrower than the front on the GT4 in order to help counter understeer, by making the rear track wider without similar increases on the front you will be increasing the car's understeer tendencies. This might not be noticeable on the road to many but if you start pushing it hard on track it can be seen alot more. Also there is the added benefit of removing a little weight from the heavy front end of the car (every little helps!), and replacing your rusty and dinged original wings with mint new ones.

Obviously the other great benefit is it will means a whole load more choice of wheels becomes available, so anyone with dreams of 10" deep dish JDM bling could be in luck."

So here's how we being.
First off we make a template using replica arches fixed exactly 20mide from the top edge of the arches.
Notice how these replica arches have the lines to retain continuity.





As you can see it's very subtle yet significant


Next off after I've sealed the arches with masking tape to ensure no leaks I'll start with the expanding foam.
