Wossner 3.2L 86.75mm 12.3:1 Pistons BMW M3 E36 (Euro) 1996-1999

Wossner are the innovative specialists for high performance pistons and connecting rods. Their products can be found in engines operating at the highest levels of motorsport, in competition and, of course, in everyday use. In fact, anywhere where longevity and operational noise are important factors. Wossner products are the source of superior power behind the success of well known motorsport teams at national and international race meets.

Extreme racing conditions demand the strength and toughness that only forged pistons can offer. Compared to cast pistons, forgings are tougher and more durable, and will stand up to the abuse that high performance motorsport applications require. Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Forgings have condensed grain that is aligned to the features of the part, which produces higher mechanical properties, and resistance to impact and fatigue.

Each forging is designed to optimize the strength-to-weight ratio, and maximize performance.
