GKTech - Z33 350Z/Z34 370Z REAR KNUCKLES WITH ALL NEW KINEMATICS (Z334-KNCK)

After spending a combined 8 years of product development and selling over 1,000 pairs of our S Chassis knuckles we naturally progressed towards the Z's. We have developed a lightweight yet strong drop knuckle. They come with dual caliper brackets as standard, high-quality PTFE lined spherical bearings throughout and have all new kinematics to drastically improve anti-squat, bump steer, camber gain curves and raised roll center height. 

- Ability to run dual caliper without spacing the rotor out
- Ability to run drum brake in standard position with dual calipers (or single caliper) installed
- The drop is 40 mm - optimized for cars 40 mm lower than factory ride height (more drop would have required proprietary arms)
- High-quality PTFE lined spherical bearings throughout as standard, common bearing size so replacements are easy to get and affordable (QA1/FK part #COM10T)
- All new kinematics to significantly increase grip over regular drop knuckles
- Optimized camber curve for more even tire wear
- Optimized bump steer for toe-in under compression without OEM arms' elastokinematics 
- Increased anti-squat for more rear weight transfer and traction
- Raised roll center height for better handling
- Lightweight sheet metal design optimized using finite element analyses for ultimate strength - fully dressed weight (bearings, spacers, circlips) 3.9kg (standard knuckle is 5.1kg)


Vehicle Compatibility:
- Nissan Z33 350z
- Infiniti G35
- Nissan Z34 370z
- Infiniti G37

INSTALLATION NOTES:

- Aftermarket toe and traction rods ARE required and MUST have rose joints as the suspension mounting points on the knuckle are significantly altered and rubber or similar wouldn't have enough misalignment to work. Lower camber arms and upper camber arms can be OEM or aftermarket and do not need to be changed. OEM bushings in lower control arms will produce different bump steer curves

- For optimal results our upper camber arms and our anti squat relocation kit.
