Product Description

The Eibach E40-72-008-01-11 is a complete front-and-rear anti-roll bar upgrade for the 987-chassis Porsche Cayman and Boxster, engineered to sharpen turn-in and reduce body roll without requiring a spring or damper change. The two bars aren't identical in construction - the front is a solid bar with 2-way adjustment, while the rear is tubular with 3-way adjustment - giving more granular tuning range at the rear where fine-tuning handling balance matters most.

Because both bars are independently adjustable, this kit lets an owner dial in the front-to-rear roll stiffness balance to suit their driving style or setup - stiffening the rear relative to the front tends to sharpen rotation into corners, while the reverse leans toward more stable, predictable handling at the limit.

Eibach designed this kit to work with both factory suspension and performance setups, so it's a reasonable standalone handling upgrade on a stock Cayman or Boxster, or a complementary piece alongside Eibach's own lowering springs and dampers for a more complete suspension package.
