Whiteline 11+ Subaru STi Front Race anti-dive caster kit

If you're looking to fine-tune your 2015-2025 Subaru WRX's suspension geometry for track or spirited driving, this anti-dive caster kit from Whiteline is a solid option. It specifically replaces the rear vertically mounted bushing on the front lower control arm, a key area for managing how your car handles during cornering and braking. This kit is designed to give you more control over your car's alignment, especially under the demands of motorsport.

What makes this kit stand out is its ability to adjust your car's caster angle. By changing the orientation of the high-performance bearings, you can achieve positive static caster gains. This helps keep your tires planted firmly on the ground during hard cornering, improving your turn-in response and making the car feel more stable when you're going straight. The lightweight aluminum housing is anodized for corrosion resistance and a clean look, and the low-compliance bearings are formulated to resist oil, grease, and weathering, ensuring they hold up under tough conditions. You can even tune the geometry from anti-lift to anti-dive using included spacers, tailoring the handling to your specific needs.

This kit comes with an installation guide to help you through the process. It's a well-built component aimed at drivers who want to extract more performance and predictable handling from their WRX STI.
