Associated B4 +8mm conversion kit

Team Associated debuted the new +8mm chassis in prototype form at the 2011 IFMAR Worlds, taking the World Championship title, TQ honors and the top two steps on the podium. Now, racers world-wide can upgrade their B4 or B4.1 to the latest specs with the new B4 +8mm Conversion Kit. The additional 8mm of added wheelbase helps make the B4 easier to drive and more stable without sacrificing the critical traction needed for lower-grip tracks. Fits B4 FT, B4.1 FT and B4 RS RTR. Some bodies may fit the longer chassis with little or no modification. Racers can purchase a +8mm B4 body from racing partners Pro-Line and JConcepts.
