Supertech valve spring kit SPRK-MC56BE
Set of valve springs MINI
29,48kg/33,6mm (65 @33,6)
Mini Cooper R56 Set of valve springs 29,48kg/33,6mm / Ratio: 4,76kg / mm (spring does only fit for OEM retainers)
With the help of Supertech valve springs & titanium valve spring retainers, higher RPM's can be run. It also eliminates valve flutter at high RPM's. At high RPM's, the rocker arms can break and the valve springs can jam. This can lead to engine damage! The Supertech valve springs have an extra adjusted spring rate.
Advantages:
- The valve train becomes lighter thanks to the titanium valve spring retainers
- The motor revs up faster
- Higher motor RPM's can be run
- The valve train becomes more stable during power increases
Likewise, we offer the full range of Supertech:
Valve keepers, mechanical tappets (rigid tappets) with matching shims and forged pistons.
