The Kartboy endlinks are some of the most popular first modifications among Subaru enthusiasts. For the price you cannot beat the bang for your buck value in terms of handling. The factory end links can soften over time. These Kartboy endlinks are made from a solid design, CNC cut and hard anodized 6061-T6 aluminum with stiff urethane bushings for the proper amount of dynamic flex. Basically a solid way of say yeah, your car is going to handle a lot better.
