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 provide you with stronger rear wheel bearings/hubs! 

Why did we go to a V2 version of our drop knuckle? We wanted to offer a new product that hasn't ever been offered on the market before. If you have owned a Miata for some time and had to do the wheel bearings, I'm sure you can understand why we went this route! However, we didn't design the V2 drop knuckle with only serviceability in mind, but also strength. the wheel hub flange on our V2 drop knuckles is now 12MM (.4750) Thick! vs the factory 3MM (.3925) flange. The flange thickness was a huge benefit to us as our shop LS3 Miata has torn off stock flange Miata hubs! 

Zerek Fab V2 Miata drop knuckles were originally designed 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 +3 degrees more of camber.

KEY FEATURES

1.5” of roll center correction, (front and rear roll center correction should be even for a balanced roll center throughout the car.)

Adjustable camber by use of rod end 

H-beam design allows us to keep the weight down while adding superior strength.

Dual caliper mounting brackets, factory sport brake calipers or any factory sport fit aftermarket calipers can be used, while now using a larger 280mm rotor without any adapters!

Factory bolt on wheel bearing and hub with 12mm flange for extra strength!

(Optional) Stainless steel extended brake line kit for dual caliper optional add-on
