Special Saenz conrods have been produced specifically for use with these pistons (see conrods for details).
Due to supply problems, we have now replaced the Cosworth pistons with a new even better design by Omega. A bespoke forging tool has been made to allow a no compromise race piston to be produced. This low deck height piston is even lighter (240gms complete), stronger & fitted with ultra low friction 2 ring pack/18mm pins it must be the ultimate race piston for the A Series engine.
These are available in .020" & 73.5mm, flat top or dished (to order). See new pics.
Please note these are not suitable for road engines.
Pictures of the old Cosworth pistons (green coating) are retained for comparison.
