A15 pistons use a shorter piston than the A12/A12A/A13/A14, but can be fitted to the other A-series engines with longer-than-stock connecting rods or by shaving the top of the block. A-series engine performance increases with longer connecting rods, if your racing rules allow!  If A15 racing pistons are used with an A12/A12A/A13/A14 engine setup, without longer con rods or shaving the block, the pistons will sit below the deck face by approximately 5mm.
