SR - Stiff Ring® Chassis Stability

What is Stiff Ring® (SR)?
SR is used to correct a vehicle's geometry setup. This is done by filling the gaps between the subframe bolts, subframe and vehicle body bolt holes. SR is manufactured using premium grade T6 automotive compliance alloy providing high corrosion resistance. 
How does SR work?
The gaps from oversized bolt holes when a vehicle is produced from factory causes shocks, vibrations and harshness. Furthermore, the uneven contact surface between the chassis and subframe produces a "spring" effect, leading to compromised vehicle handling. 
Installing SR eliminates the gaps that causes the subframe and body to misalign. 
Benefits of SR:
  • Improved handling
  • Improved steering response
  • Precise turning angle
  • Reduction of NVH level (noise, vibration and harshness)
  • Increased cabin comfort
  • Prolong lifespan of undercarriage parts
