Subaru Impreza is good performance car designed for rally. Because of its good performance it’s more and more used for grip racing as well. Lowering the car will give more grip and better handling, but then the factory designed kinematics won’t work as they are supposed to. Wisefab Subaru Impreza uprights / knuckles bring the roll center, bumpsteer, anti-squat and camber curve back to normal range, provide better roll stiffness, handling and grip.
- -1 kg lighter over OEM knuckle / upright
But still maintaining required strength and stiffness
- Roll center correction
-50mm drop from the knuckle / upright
- 2000 - 2007 WRX/STI 72x42x52 wheel bearing needs to be used
Either 5x100 hub (28462FE001) or 5x114,3 hub (28462FE011) can be used. Both are for STI/WRX 72x42x52 wheel bearing
- Brake caliper tabs moved to upright / knuckle
In OEM solution the rear brake caliper attached to the dust shield. Wisefab solution provides higher stiffness for brake caliper
- OEM handbrake fitment
OEM handbrake can be used, but the brake caliper tabs need to be removed for clearance
- CrMo sphericals
Traction link bushing replaced with spherical bearing
- Knuckles with hardware
- Installation guide
- Can be used with OEM shock and spring, but bigger benefit can be achieved with lower springs or aftermarket coilovers.
- Original wheel speed sensor can be used
- This knuckle can be used on GC, GD Impreza and SF, SG Foresters.
