Tribute Automotive is on a distinguished road
Default Stage 4

As the new GRP rear section, and hence the replacement wheels, will be wider than the original MX5 it is necessary to "roll out" the lip of the rear wheel arches to provided tyre clearance.

Jack up the rear of the car, support on axles stands, and remove the rear wheels.

Using a pair of Mole grips bend the inner lip down as shown.

Work your my around the arch from where the rear bumper would be, until you are about 150mm above the sill.

Next push the Mole grips as far over the edge of the arch as possible, as shown, and bend upwards until the lip is at 90 degrees. Work around the whole arch as before.

You will need to use a pair of hammers to push the arch into it's finished shape (unfinished arch shown below).
