Schrick Valve Spring - E30 M3, E36 M3 Euro S50

Dual valve spring (inner + outer) designed specifically for S14 and Euro S50 race applications. This spring can accommodate valve lift up to 13.0mm whereas the factory Motorsport springs are designed for stock/Evo cams and stock valves. Having the correct height spring is just as important as a capable rate.

When using Schrick race cams (308, 320), different retainers, seats, keepers, tappets, and valves are called for (in addition to these springs). Race cams should only be used as a complete engine build with all of the parts engineered to work together. Call or email us for the complete list and pricing on the full Schrick valve package.
