After nearly 2 years in development, countless prototypes and revisions GKTech has a lightweight yet strong drop knuckle for the R32 chassis Nissan's. 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, bumpsteer, cambergain 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 1.57'' (40mm) - optimized for cars 1.57'' (40mm) 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 bumpsteer 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
  • Light weight sheet metal design optimized using finite element analyses for ultimate strength - fully dressed weight (bearings, spacers, circlips) 4.1kg (standard knuckle is 5.1kg)
  • Clearance for larger GTR drive shafts

Installation notes:

  • To be mounted with bearing mounting holes perpendicular to the ground in static height (extended LCA's that push the wheel out to the rear of the wheel arch will NOT work well, or at all if extended too far out). Note that our rear LCA's adjust perpendicular to the center line of the car, which makes sense.
  • Will fit all R chassis' with the use of an S chassis style lower coilover mounting, S13/R32/Z32 and to get the most out of the kinematics improvements, an R33/R34 rear subframe is suggested. Alternatively the lower control arm front pivot point can be moved up.
  • Will clear 17" rims (and even 16" rims with low offsets) and all 18" rims but please note that the closer the rim sits in the wheel-well, the greater the chance that the toe arm mount will come close to hitting. A 17x10.5 +22 Enkei RPF1 wheel was tested and still has around 0.19'' (5mm) of clearance (ample)
  • Aftermarket camber, toe and traction rods ARE required and MUST have heim joints as the suspension mounting points on the knuckle are in significantly altered and rubber or similar wouldn't have enough misalignment to work. Lower control arms can be OEM or aftermarket and do not need to be changed. OEM bushings in lower control arms will produce different bumpsteer curves
  • The Wilwood dual caliper bracket that we offer do NOT fit on these knuckles
