AV1804 series of 1mm Offset Insert Bushings allow for a new range of tuning using your kit supplied suspension mounts.    After hours of testing, the AVID team is offering up this simple solution to allow racers to customize their suspension to get lower rear roll centers and adjust rear toe-in to 1,2,3, 4 or 5 degrees as well as being able to move all of the other pivots on the chassis.  The combinations are practically endless, but as we find out new setups they will be posted on the AV1804 product page at:  http://www.avidrc.com/product/5/accesories/435/RC82-1mm-Offset-Insert-1-Dot-AV1804-1DOT-accesories.html
