Topline Yokomo RD/SD V2 Lightweight High-Traction Rear Suspension Arms
For RD/SD drivers looking to sharpen their car's behavior at every corner of the track, these V2 rear suspension arms from Topline offer a meaningful step up from stock. Machined from Delrin, the arms strike a balance between structural integrity and low mass — keeping unsprung weight down to improve acceleration response and overall agility without sacrificing the durability needed for consistent performance. High-traction surface geometry translates to better grip and a more confident throttle kick-off out of corners. A symmetrical design means each arm can be flipped to run on either side, which not only simplifies installation but distributes wear evenly to extend the lifespan of the parts. Available in 42mm and 45mm lengths to suit different setup preferences.
Features:
- Machined Delrin construction for a combination of durability and smooth, precise movement
- Lightweight build reduces unsprung weight and sharpens acceleration response
- High-traction surface design improves grip and throttle kick-off feel
- Enhances steering precision and cornering stability
- Symmetrical, reversible fitment — installs on left or right side interchangeably
