The PSM rear knuckles are designed to fit Z32 two piston calipers but can also be fitted with Wilwood and other popular calipers with optional adaptor brackets. The rear knuckles eliminate the need for backing plate-type secondary caliper brackets and offer a simpler and much stronger way to mount your drift brake. The knuckles can also accommodate the z32 drum style parking brake.
The PSM knuckles come with pressed in spherical bearings that eliminate squishy rubber bushings that allow flex that can compromise your alignment settings and cause unpredictable handling.
Toe-out, neutral toe and two levels of toe-in curves can be set depending on what hole location is chosen on the knuckle and toe rod on the bracket. The ability to adjust toe curves quickly is a huge advantage for both drifting and grip driving, as it greatly affects how the car reacts to on and off throttle input.
We would not hesitate to use these rear knuckles on a grip car at all.
Many other drifting angle kits simply remove the swaybar, but this is detrimental to handling. The bracket kit can remove up to 38mm off the sway bar width which also stiffens the sway bar torsionally.
