What This Product Does:
- Holding the torsion bar end and anchoring it to the chassis or suspension structure.
- Providing a mounting surface for the torsion bar to twist against, effectively managing the rear spring action (torsional stiffness).
- The adjustable aspect allows you to change preload, camber, or ride height for tuning the rear suspension setup to your desired performance balance (road or track)
- Helping maintain correct geometry as suspension moves, ensuring better tire contact, handling, and responsiveness.
- Rust / corrosion / fatigue: The old plates may be rusty or weakened, especially in classic cars.
- Sagging or misalignment: Rear ride height may fall, or camber might drift under load.
- Uneven tire wear: Because geometry is off or not held firmly, the tires may wear more on one edge.
- Poor rear handling / unpredictable grip: The rear may feel loose under cornering or shift unpredictably under load.
- Difficulty setting or maintaining geometry: Without adjustability, it’s harder to dial in suspension tweaks, especially for track use or changed setups (wider tires, stiffer suspension, etc.).
Factory spring plates offer limited adjustment. This RS-style sports version allows quick and accurate tuning of ride height, preload, and camber, giving sharper handling and better tire contact for both road and track.
