R1WURKS (B84 Series) Aluminum LRC Rear Arm Mount Set
These arm mounts provide a lowered range of rear pivot adjustments with a lowered pill position, offering additional low roll center options. A lower roll center can improve traction on mid to low-grip tracks by allowing the suspension to better manage weight transfer.
Potential performance benefits or handling advantages when using LRC:
- Improved Traction During Acceleration
- Gentler Load Transfer in Corners
- Enhanced Cornering Stability
- Better Bump Compliance
- More Predictable Handling
Features and Specifications:
- Lightweight: 6.7 g per pair
- High-strength: 7075-T6 aluminum alloy
- Sleek anodized black finish with laser etching
Note:
- Using these blocks may require additional suspension adjustments to optimize performance, including slightly stiffer springs and anti-roll bar settings, depending on track conditions and grip levels.
- If you decide not to install the rear bumper, use M3×18 mm screws to mount the LRC D-Block.
