Manufactured from a far superior aluminium than most high performance pistons, it contains a much higher silicon content. Using advanced heat treatments, a more heat-stable piston is created. This dramatically reduces expansion under combustion/running conditions. Consequently lower piston to bore clearances are required, maximising piston stability in the bore, and therefore better piston ring sealing. Extremely robust.

Extensively tested in race use for over 1,000 miles, including the 2025 6 hours Le mans Classic, they performed faultlessly.

Flat top as standard, a reasonably big capacity dish can be machined in to the crowns if required.

Piston weight - 0.356 grams
Assembly weight - 0.471 grams
Crown thickness - 0.292"
Minimum crown thickness recommended when machining in dishes - 0.180" race, 0.160" road with moderate CR.
Ring pack - NPR, 1,0mm top ring, 1,2mm 2nd ring, 2,75mm oil control ring.
