T Sportline's Radius Arm Double Offset Bushing or Hybrid Bearing Kits are designed to improve cornering grip and Tesla Model 3 / Y straight line stability. These kits are supplied with either a dual offset bushing (street use) or a hybrid bearing (track use) encased in poly bushings to give greater steering feel, more steering weight, greater precision all through increased static caster and dynamic negative camber gain. In addition, T Sportline bushings and hybrid bearings provide improved braking performance, and less under load alignment change.

Our Double Offset Bushings and Hybrid Bearings are crafted by Tesla enthusiast drivers for Tesla enthusiast drivers looking to improve road feel and handling.  Bushings are perfect for street-focused enthusiasts while our Hybrid Bearings is intended for weekend warrior and full-race applications. Each kit is built to heavy-duty specifications, and both are compatible with stock radius arms (press-in installation).  We do not recommend the hybrid bearing for street-use-focused cars; the hybrid bearing is intended for mostly track use.
