VAC Motorsports Valve Springs

What makes our springs the unequivocal choice for the performance and racing BMW owner? Read on...
VAC's High Performance Valve Springs are a dual-spring interference design that is made from pure H-11 alloy. Each spring is wound to meet our rate requirements and is shot-peened for stress relief. The proprietary interference fit used helps to control harmonic resonance that naturally occurs in springs across the entire rev range. With the dual-spring configuration, should something happen to one spring, the other can prevent the valve from dropping and causing catastrophic engine damage. VAC springs are ready to be set to the ideal seat pressure for performance camshafts from Cat, VAC, Schrick and others. You may adjust spring seat thickness to adjust seat pressure.

These springs are fully compatible with both the OEM retainers or VAC Light weight Steel-alloy or Titanium retainers, found below With precise specs and consistent quality, these springs are physically capable of revving to bursts of nearly 11,000 RPM for added peace of mind and maximum performance.

VAC springs have been used in VAC's World Challenge Touring Car, GT3 car, C-Mod E36 'Silver bullet', E46 BMW CCA 4dr, and E46 M3 raceer, as well as in thousands of race engines for years with excellent results. Designed with the aid of a BMW Formula-1 engineer; these springs are guaranteed to out perform the competitions valve springs at any price.
