GSC Power-Division Beehive Spring Kit with Titanium Retainers for the Subaru 2015 WRX, BRZ and Toyota GT86 includes 16 titanium retainers, 16 beehive valve springs, and 16 spring seats. Our beehive spring utilizes advanced material heat treatment methods for superior load loss capabilities. These springs have the highest level of spring load retention while still maintaining good fatigue throughout the life of the spring. Beehive springs allow for the use of a smaller, lighter retainer allowing for higher RPM and more valve control. This is absolutely the most lightweight, strongest spring kit for the FA20 platform
