Purchase VAC S14 High Performance Valve Spring & Retainer Kit, E30 M3
Our Spring Kits feature a custom dual spring capable of turning 12,000 RPM for that added piece of mind (Over-rev/Mis-shift). Our springs are shot-peened for stress relief and interference fit to control harmonic resonance across the rev range. Also in the dual spring configuration, should something happen to one spring, the other prevents the valve from dropping and causing catastrophic damage. Our springs are also capable of handling much higher lift to handle even the most aggressive of cams like the Schrick 320 degree cams. These springs have been compatible with every camshaft we have ever installed. After rigorous testing in our 2.5L Stroker Engine for 4 years, these Valve Springs still tests within 2% of their original rate. We believe they are the best spring available for your BMW anywhere.
This kit includes:
- 16 High Performance Dual Valve Springs
- 16 Steel or Titanium Valve Retainers
- Shims
- All Parts are MADE IN USA
*Note: Due to the nature of titanium retainers, while they are suitable for a street car, it is only recommended they be installed in a valve train that will be inspected from time to time. Steel is still a great choice for a street or track oriented car or you can chose our shim-under kit for the lightest weight, highest performance, and reliable valve train.*
