Miata Drop Knuckles - Rear

Zerek Fabrication Miata rear drop knuckles give you the most amount of suspension geometry correction over any other knuckle on the market. From drift to grip, the use of a drop knuckle will lower your center of gravity and reduce dynamic bumpsteer.

Zerek Fab Miata drop knuckles were originally designed in Solidworks, off a full 3D scan of the Miata suspension. This allows us to fine tune specs and pinpoint exactly where we need to adjust geometry at a lowered ride height, while also giving roll correction and higher steering angle. Once the design was finalized, rigorous FEA (Finite Element Analysis) testing was completed at 4 times the weight of the vehicle per corner. This ensures the strength and integrity of our product's performance. We recommend the use of our front drop knuckle in conjunction with the rear to keep proper geometry consistent throughout the entire car.

 

Zerek Fab rear drop knuckles are the only knuckle that will allow you to adjust camber by the rod end design! Every half turn is equal to .25 degrees of camber. This enables you to run -2 degrees more or +3 degrees more of camber.
