Ferrea Valve Springs - Mini Cooper
For ALL racing environments!

Developed from high strength alloys
Springs are heat treated and stress relieved = increase in spring's life!
Provide stability needed for high lift and high RPM.
Minimizes load loss for today's aggressive valvetrain combo's.

"Harmonics or high frequency fatigue is present in ALL racing engines and will usually destroy the valvetrain if not controlled! Properly designed valve springs will control the dominant harmonics, provide the needed stability, and reduce valvetrain component wear."

IMPORTANT: All Valve Springs require Retainers and Spring Seat Locators. See requirements listed under Part #'s.
