Wiseco pistons are a high quality forged stock replacement piston.  These pistons can be used with stock or aftermarket connecting rods (but not with the Carrillo rods without machine work to the rods).  These come in the standard 8.5:1 compression ratio for they MINI, and have the bore options of  standard (77mm) and 0.020in over bore (77.5mm).  They are forged, so they'll handle any amount of boost you can throw at them, but lightweight so all that power gets to the ground.  Sold in sets of 4 and include pistons, rings and wrist pins.
