2. Paint stripping + Reinforcement of the body shell
Via hydro-blasting dirt, varnish and undercoating is being removed. Working on the bare metal we strengthen the body at critical points through welding seams, as factory-provided welding spots do not provide sufficient firmness for increased engine performance. Back in the days this was accounted for by Porsche by building homologation cars for racing (RS types) which were rewelded in the factory. >>Link<<
Frequently, customers ask for the installation of a roll cage or a bolted cage and to ensure the necessary strength, the respective reference points are reinforced accordingly (this also applies to the attachment points of optionally installed 6 point girth).
Cages are welded and certified according to DMSB / FIA guidelines made of ST52 steel 45x3mm. (NHRA, SBF, MSA, FHRA, NDCD have the same guidelines) Each body is then provided with a strength report at the TÜV. >>Link<<
3. Corrosion protection
For Porsche vehicles since the model year 1976, the bodies are fully galvanized (then with 6 years warranty) and therefore we also choose the method of water-based paint stripping (hydro-blasting), because the galvanizing as a corrosion protection layer is not damaged. The welded parts (or replaced body components) are galvanized accordingly. Of course, other corrosion protection measures (especially in older models) are possible, such as the KTL immersion coating in which a corrosion protection varnish with a layer thickness between 10 and 40 μ is applied.
4. Body structure
For the completion of the body usually the original parts which have been also stripped, tested (if necessary, repaired) or replaced by new parts with the same parts number are used. On customer's request, it is of course possible to replace standard parts, such as roofs, hoods, spoilers or doors (but only with simultaneous installation of a cage) by considerably lighter carbon parts.
