Wossner Forged Piston Mini R55 R56 Cooper S JCW Gen 2

BMW Mini Cooper S R56 1.6 16v (Turbocharged 2007-Present) Wossner Forged Piston Kit.

W?ssner are regarded by Europe?s leading motor sport engine builders as being the piston of choice when building an engine not only to perform, but to withstand the stresses and duress?s of competition life. W?ssner pistons feature a unique Moly coating on the skirts and a grade of 4032 Alloy (T6) which allows the engine builder to run a closer piston to bore tolerance then he might do on another make of piston. This helps remove the slapping noise during cold start, common place among engines running forged pistons due to larger then OE bore clearances. The crowns of the pistons are also mirror polished to better resist detonation on a high performance engine. Mirror polishing allows a more even spread of heat inside the chamber which will help prevent ?hot spots? on piston crowns. Price includes all piston rings and gudgeon pins.
