D1SPEC Rear Knuckle Pillow & Collar Set (SR Series)

With genuine rubber bushings, the case and rubber are fixed together, resulting in an unstable pivot point due to twisting, bending, and compression, limiting the range of motion and causing constant alignment fluctuations. Furthermore, the constant rebound force of the rubber continuously affects the suspension's movement while driving. By replacing these rubber bushings with pillow ball bushings, twisting, bending, and compression are eliminated, the pivot point remains constant, and alignment changes are eliminated. The suspension moves smoothly without being subjected to load, virtually eliminating changes in behavior during drifting, and allowing the vehicle to perform at its full potential even in situations where traction was previously lacking.
