Spoox Motorsport only supply the finest forged pistons available in Europe. Wössner 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. Wössner 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.
Imported from Sweden these Con-rods have been designed, manufactured and tested to the highest levels of scrutiny before being released to the trade and the public alike. These lightweight, H-beam section connecting rods are forged from AISI 4340 (En24) steel. Heat treated to HRC 35-38 and fully shot-peened for higher fatigue strength.
