Subaru BRZ Valve Spring Kit - GSC Power Division - Single Beehive Titanium Retainers/Chromoly Seats - 13-15. This GSC P-D single beehive valve spring kit is a direct-fit upgrade for 2013–2015 BRZ/Scion FR-S (FA20) engines, replacing stock springs and hardware with lighter, stronger components.

The kit reduces reciprocating mass and improves valve control compared with stock components, making it a suitable choice for enthusiasts running higher RPMs, mild to aggressive cams, or planning further tuning. GSC Power Division’s single beehive springs are designed to provide stable spring pressure through the valve’s lift range while titanium retainers cut weight at the top end and chromoly seats offer durable contact surfaces. This package keeps installation straightforward while upgrading the critical components of the valvetrain.
