Xtreme Rotaries, in collaboration with Racecast, is proud to release the 20B Cast Centre Plate — the result of years of research, development, and extensive real-world testing. Designed specifically for high-performance rotary applications, this centre plate delivers maximum durability, reliability, and versatility for professional engine builders.

 

 

Key Features:

  • Enhanced Structural Strength
