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.\u003cbr\u003e\u003cbr\u003eIncludes 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. \u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eCrafted 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. \u003cbr\u003e\u003cbr\u003eThis reduces unsprung weight, improves handling, and increases overall performance.
