German brand PSM have introduced the innovative battery positioning system for the Team Associated B6 and B6.1. This battery positioning system is designed to hold the battery securely in place while maintaining the option to move it forward and backwards. PSM have added the feature to hold it down with the included industrial o-rings to achieve an incredible clean look and super quick battery changes.

The braceless design will allow a greater amount of linear torsion around the center area, this means the car can develop more overall traction. PSM recommend this system for 17.5T or stock drivers in general. It will work for modified as well, but may feel a little twitchy at higher speeds / fast sweeping corners due to the amount of torsion. However, depending on your personal preference or driving style it may feel just right.
