adjustable coilover kits, and adjustable suspension arms intended to increase steering angle, lower ride height, and refine handling behavior. E-Factory Performance supplies these parts as hardware upgrades suited to grassroots drifting, track-day use, and modified street cars that require precise alignment and chassis adjustment. The company also offers related components such as offset steering rack bushings, rear traction arms, and upper control arms for additional geometry tuning. In addition to parts, E-Factory Performance provides a knuckle core service that prepares knuckles for coilover installation. Products are sold through an online storefront that also carries branded apparel.
