Authentic GKTECH rear Drop Knuckles w/ Kinematics 2013-2022 BRZ / 2013-2016 FRS / 2017-2021 86 / 2022-2024 GR86

Bringing a combined 8 years of development and selling over 1,000 pairs ofS and Z chassis knuckles, we bring you our FR-R/GR86 / BRZ rear drop knuckle providing a range of features that will transform your driving experience. The 40mm drop knuckle is specifically designed to accommodate lowered cars, including 25mm of roll center correction; this ensures optimal suspension geometry and improved handling. An optimized camber curve ensures even tire wear along with optimized bump steer which when used with our relocated traction arm results in toe-in under both compression and extension, providing you with increased corner exit grip and more consistent handling.
Includes a provision for dual calipers to run a hydraulic e-brake and whether you have Brembo, GT, or GTS calipers, our knuckle is fully compatible. We understand the importance of retaining the OEM e-brake assembly and ABS system, which is why our knuckle is designed to seamlessly integrate with them without any compromises.Crafted from high-strength 4130 chromoly steel using a sheet metal design, our knuckle offers unrivaled strength and durability. Extensive finite element analyses have been conducted to optimize its lightweight construction, resulting in a fully dressed weight of just 8.6lb, significantly lighter than standard knuckles at 15.2lb.
This reduces unsprung weight, improves handling, and increases overall performance. These knuckles utilise common sized high quality PTFE lined bearings which reduce OEM bushing elastokinematics and are easily replaceable and affordable (QA1/FK part #COM10T)
