Wisefab Rear Suspension Drop Knuckle Kit, Toyota Supra JZA80 MK4 (WF180)

Rear suspension kit for the MK4 Supra that corrects the geometry once the car is lowered. It brings the roll centre back up, cuts camber gain, and switches the factory negative anti-squat to slightly positive so the rear stays settled under power. Wisefab pitches it for drift, drag and circuit use.

Fits

• Toyota Supra (JZA80)

Before you order

• Coilovers required. Designed around a ride height of about 80 mm from the front subframe to the ground, with the rear set to match.
• Minimum wheel size is 17 in. Wisefab tested 9.5x18 ET35 wheels and tires up to 265/35R18; inner wheel wells may need light trimming depending on wheel width and offset.
• Hub-to-hub track stays the same as factory because it is set by the halfshaft length.
• Wisefab notes the kit also fits a Toyota Soarer once a MK4 Supra rear subframe is installed.

Highlights

• Higher rear roll centre on a lowered car for more roll stiffness
• Reduced camber gain compared with the factory setup, which already gains a lot when lowered
• Anti-squat changed from negative to slightly positive for a more stable rear under acceleration
• Three shock positions on the arm change motion ratio, so you can tune stiffness without new springs or resetting ride height
• Links come pre-set from Wisefab: after installation and a toe alignment the car is ready to drive.

In the kit

• Pre-set suspension control arms
• Knuckles with hardware
• Installation guide
