Restore Steering Feel on Your Miata or RX-8
Worn front lower inner control arm bushings let the whole front end shift under braking and hard cornering, dulling steering feedback and speeding up tire wear. The Whiteline W53413 replaces the soft factory rubber with a synthetic elastomer bushing kit that locks the control arm in place for sharper turn-in and more predictable front-end response.
Key Features
- Synthetic elastomer bushings replace worn factory rubber at the front lower inner mounting point
- Sharper steering response and reduced deflection under hard cornering and braking
- Slows uneven front tire wear caused by bushing play
- Built for daily driving, autocross, and track use
- Backed by a Whiteline Limited Lifetime Warranty
