Product Details

These Yellow Speed Premium Competition coilovers fit the 2005-2011 Mercedes-Benz SLK-Class. They deliver race-ready performance for track day enthusiasts, weekend racers, and club-level competitors without sacrificing daily drivability. Featuring inverted front strut technology for increased rigidity and reduced flex, this 1-way damping adjustable system gives drivers precise control over chassis behavior across varied driving conditions.

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 Premium Comp coilover system is built to order, ensuring precise assembly and quality control for every application.

Features

  • 1-way damping adjustment with 33 levels of combined rebound and compression 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
