Porsche 2.8 RSR arch fitment

Since steel 2.8 RSR (or 2.5ST) wings are not available we need to modify standard wings, using a pressed steel arch panel.

Firstly the lower section of the wing is cut away to allow proper alignment of the new arch

The front of the arch is clamped in place and the original wing strengthener reshaped to match the profile

The rest of the original arch is cut away

And the new arch clamped in place


The front is spotwelded

And the rear folded over the inner filet as original

The remainder is tacked in place and the clamps removed

Before being fully welded

And then ground back

To give a near invisible join
