105/115 series engine compartment strengthening panels. These panels fit in the area behind where the steering box and idler mount on the outside of the inner wing. Providing extra support and strengthening whilst also cutting down on unwanted body flex. The design of these particular panels is far superior to others on the market as they have a 90 degree return panel which welds to the chassis as well - providing lateral bracing in addition to just extra material thickness. They are also a stamped panel not simply a laser cut flat sheet - so they fit into the inner wing profile.
