GSC P-D Single Beehive Spring Kit Titanium Retainers/Chromoly Seats 13-15 Scion FR-S / BRZ FA20

If you're looking to get more out of your FA20 engine in your 2013-2017 Subaru BRZ or 2013-2016 Scion FR-S, this GSC Power Division single beehive spring kit is a solid option. This kit is designed to handle higher RPMs and more aggressive camshaft profiles, which is common when rebuilding the top end of these popular sports cars. The beehive shape helps reduce retainer weight and allows for a smaller, lighter spring seat, contributing to overall valve train stability at high speeds.

What sets this kit apart is the use of lightweight titanium retainers. Titanium is significantly lighter than steel, which reduces the mass that the valve spring has to control. This means less stress on the spring and improved valve control, especially as you push the engine harder. The springs themselves are well-built single beehive springs, and the kit includes chromoly steel spring seats for a solid foundation. This combination is a popular choice for enthusiasts looking for improved valve train reliability and performance.

When installing this kit, remember that it's part of a larger engine build. You'll want to ensure all other components in your valve train are in good condition and compatible with the increased spring pressure. Refer to the manufacturer's installation instructions for specific details on proper setup and any required tools.
