Description:

• These small aluminum rings make a night & day difference in the way your Kia Optima or Hyundai Sonata feels when doing day to day driving
• Used to correct the chassis's basic geometry by filling the gap between the subframe bolts, subframe, and the car's chassis bolt holes
• The vehicle's engine, transmission, suspension, and the uni-body are mounted on the subframe and when installed, these work by correcting the geometry setup
• By eliminating the gap, vibration through the chassis is greatly reduced improving driver feedback
• Helps to protect & prolong the vehicle's undercarriage parts lifespan. Eg: Steering rack, lower control arms, etc
• Stiff Ring chassis collars are made of a special grade of aluminum alloy
• Your vehicle's handling will be improved significantly with these installed
