Product Details

These Yellow Speed Inverted Pro Street coilovers fit the 2011-2015 Kia Optima FWD (TF). They deliver a high-performance street suspension upgrade with inverted front strut technology for increased rigidity and reduced unsprung weight. Featuring 1-way damping adjustment, this system allows drivers to fine-tune ride quality and handling characteristics for both daily driving and spirited street use.

The inverted strut design places the larger-diameter tube at the bottom, closer to the wheel, providing improved lateral stiffness and more precise steering response. Full-length ride height adjustment via the lower bracket allows stance and weight distribution tuning without compromising suspension travel.

Each Yellow Speed Racing Inverted Pro Street coilover system is built to order, ensuring precise assembly and quality control for every application.

Features

  • 1-way damping adjustment with 16 clicks of rebound control
  • Inverted front strut design for increased rigidity and reduced flex
  • Full-length ride height adjustment via lower bracket
  • Monotube internal design with 52mm shock body (MacPherson strut type)
  • High-rigidity SAE9254 steel springs for long-term durability
  • Spring bearing top for smoother handling response and reduced spring noise
  • Electroplated shock body for corrosion resistance
  • Built to order for precise fitment and quality assurance
