C4 Reference Library

Welcome to our new C4 Reference Library.  With the changes we've made to our business there are many more options for buying the C4 rear suspension kits.  As such, we wanted to make sure that our customers had all they information they needed to complete a successful installation.


If you check out our C4 suspension order center you'll see that almost everything can be added as an option to a base set of trailing arms or camber rods.  A customer can now buy as little as the suspension links themselves and make their own spacer and re-use the OE hardware or can add on spacers and new mounting bolts to reduce the amount of parts that need to be fabricated.


A similar thing exists for the camber rod adapter plates.  These are now an option to buy, or if you would like to make your own you can see guidelines for doing that as well.


So with all of that said we now have a number of documents that outline how to make spacers, camber rod adapter plates and the shims necessary if you use the optional BMS tapered spacer kit.  There are also installation instructions for the trailing arms and camber rods.


Use the links below to find & download what you need and if you have any questions please don't hesitate to contact us.
