We are just a couple of gear heads who love spending our time building Datsuns. Everything we do with JBC is driven by the desires we have for our personal projects. JBC materialized from our common interests in these cars as well as our desire to share the designs and knowledge we develop along the way. Time is our biggest limitation, we have a ton of components we plan to build however life, family, day jobs and the mentioned personal projects often make the development pace a lot slower than we wish. We hope to provide our Datsun friends with fun parts for years to come.

Lately, we have been auto crossing and endurance racing our 510s.  As all of you are aware the loose steering box in the 510 is less than desirable.  Over four years ago we set out a task to draw the Datsun 510 front suspension in CAD and from that model make a new cross member for rack and pinion that is perfect for everything from a rally car to a slammed street car with just a few adjustments. Simple right?  

After modeling, prototyping, modifying and endless testing we came to the conclusion that to get proper geometry we would need to decide on one suspension setup and design it for those parameters.  Since we both love daily driving our cars and auto crossing, we decided to build the suspension to be enjoyable on the streets as well as perform well on the track, then if anyone shares the same interests they can pick one up and enjoy our design.  

There is a comprehensive document in the technical info. section for those of you who want to geek out on all the math, physics, and proper race car etiquette, which then gets ruined with slip angles and component deflection.  

Happy Racing.
