Adjustable short-type main lower arm

Product Description:

THE high precision upper arm with bearings for the GRK5 is now available as a premium option.

• Support with integrated bearings: combines high rigidity with optimal adaptation to variations in the road surface.

• Reduction of installation clearances: minimizes vibration and geometry changes related to inputs and movements.

• Improved performance: provides precise tracking in the front and improves traction in the rear.

• GRK5 (standard part).

• GRK4 (Under certain conditions, see remarks below).

• GRK Global Series (RWD version) (Under certain conditions, see remarks below).

Compatibility Notes:

1. Front side:

• Not compatible if it interferes with the innermost mounting point.

• Not compatible with vehicles equipped with a resin nose cone.

2. Rear side:

• Not compatible if it interferes with the innermost mounting point.

3. Replacement on GRK Global Series:

• Requires a D-cut type upper shaft (e.g. S001/S012) and an M3 fixing screw for installation.

• 2 pieces

Ce composant est une pièce optionnelle destinée aux châssis Shibata R31House équipés du système Adjustable Geometry.

Non utilisable seul — nécessite les pièces R31S322 ou R31S315 pour être monté.

• Increased rigidity: thanks to the bearing support, reducing deformation under stress.

• Vibration reduction: offers stable and consistent geometry in drift conditions.

• Adaptability: designed to meet the needs of demanding RWD drivers.
