Nissan S13 Rear Kit

Revised kinematics, not just dropped knuckle.

Dropped knuckles are good  to maintain factory kinematics on lowered car, but still factory kinematics is more designed for everyday streetcar. If maximum grip is the keyword and combination of good roll centre position, camber gain, antisquat and bumpsteer are required, then dropped knuckle is not good enough. That is the reason why we totally revised the kinematics.

More than 10kg of weight reduction over original components and still maintaining required strength and stiffness

All the metal components on Wisefab S-Chassis knuckle are from high strenght steel, including sheetmetal components, tubes, tube ends and rod end housings. Good materials with design optimization has lead into major weight reduction. The knuckle weighs ~2,7kg and at the same time can hold 5-6G of loadpeak at tire contact patch on 1100kg car. Also for weight reduction purposes most of  the suspension links are designed straight and tubular. All the joints are rod ends or spherical bearings, no rubber bushings.

Other components

Hub to hub length (track) is the same as original, as this is defined by halfshaft lengths.
This kit assumes coilovers to adjust ride height

Minimum rim size is 17“
