Tamiya David Jun Pro-Module Rear suspension
 

Forgot I had this, it came out originally in 2005 I believe.

Info from Tamiya:

The Pro-Module Rear Suspension incorporates the upper link and wheel hub as part of the dampening system as apposed to a conventional design. This effectively creates a linkage system (cantilever) with no additional moving parts. The result is a reactive and exponential dampening geometry to enhance control and drivability.
Both the arms and hubs are machined aluminum finished with a bold anodized plating. Hubs feature 0 deg. of toe.

I will have a look to see if i still have the springs.

I have no idea what this is worth so open to offers...

Thanks
