Description
Whiteline 09+ Ford Fiesta / 09+ Mazda 2DE Front Caster Correction C / A L / I Rear Bushing — For a performance alignment, caster is a dynamic tool: it changes how the outside front tire is presented to the road as steering angle increases.
Caster affects steering feel and dynamic camber as steering angle builds, while anti-lift/anti-dive geometry influences how the chassis manages longitudinal load. The exact change depends on the Whiteline SKU and vehicle, so final setup should be verified with a proper alignment.
Technical Overview
- Position: Front & Rear
- Whiteline part number: KCA426
Who This Is For
Best for alignment-focused street, autocross or track builds where front-end geometry and dynamic tire behavior matter more than retaining completely stock suspension compliance.
Installation & Setup
Perform a professional alignment after installation and evaluate caster together with camber and toe rather than as an isolated number.
