Product Details

Koni Sport Yellows are the benchmark adjustable shock for street and track on the 2004-2009 Mazda Mazdaspeed3. Each damper offers externally adjustable rebound that lets you dial body control without sacrificing daily comfort — the right answer for owners running stock or lowering springs who want sharper turn-in and confidence on canyon roads.

Rebound is adjustable at the shock body across the full damping range, so you can soften for daily duty and stiffen for autocross or trackday weekends. Each Koni Sport shock is rebuildable and revalvable — this is suspension hardware you keep for the life of the car.

Features

  • Externally adjustable rebound damping — tune body control without changing springs
  • Twin-tube hydraulic design with hardened chrome rod for daily-driver durability
  • Pairs perfectly with stock or lowering springs (drop up to ~35 mm typical)
  • Rebuildable and revalvable construction — a lifetime suspension investment
  • Made in the Netherlands by Koni's OE shock division
  • Backed by Koni's lifetime workmanship warranty
