2005-2012 Porsche Boxster / Cayman 987 Traction Plus Ultra Coilovers

Enhance the precision and composure of your 2005-2012 Porsche Boxster / Cayman 987 with Riaction Traction Plus Ultra coilovers. Designed for mid-engine performance platforms, the TPU system sharpens steering feedback, reduces body roll, and delivers improved balance through high-speed corners without compromising chassis refinement.

At the core of Traction Plus Ultra is our new digressive piston design, engineered to provide firm low-speed damping for improved front-end response and roll control while maintaining compliance over surface irregularities. On the 987 chassis, this results in more stable braking zones, smoother weight transfer, and increased confidence during spirited driving or track sessions.

Each kit features a nickel-coated shock body for enhanced corrosion resistance and long-term durability. The hex screw preload collar locking system secures spring preload under repeated load cycles, while our signature orange coating on non-MacPherson components adds both protection and a distinctive performance appearance. Pillowball upper mounts are included where applicable to maximize steering precision and suspension articulation.

Every Traction Plus Ultra system is backed by our 2-year factory warranty.
