Had to cut around pedal box and scuttle panel. Would not fit in 1 piece? To be glued in place later.

Now to join up the holes. Must make sure it is the right holes so placed tape on to show clearly

Done, now to clean up the holes

Does it fit? Mark up top edge ready to trim to fit perfectly

And trim line where the sill protector is. Sill will be internal not over hanging.

Checking fit against the front edge.

Trail fitting of side skin.

Kevlar / foam composite crash protection

It will absorb more energy and sharp impacts are less likely to penetrate through. With Aluminium honeycombe energy is transferred from one surface to the other, with this special foam, designed for the job, localised absorbtion is the key.

Cross section of the sandwich crash protection. Lighter than the aluminium honeycomb.

With the added 1.3 - 1.4 mm thick laminate on each side these panels are lighter and should be more efficient than other alternatives.
