All New RX28 Steel Chassis for your RX28G2 Plate Cars.  This new chassis allow for fore and aft movement of 20mm wide batteries as well as making it compatible with our new 400mah batteries that are 24mm wide.  This new chassis kit comes with lateral CF braces to locate the battery side to side, but also to stiffen the front to back structure of the car for more precise handling and higher corner speeds.  The kit is finished off with a new forward center shock mount that incorporates a band-less battery hold down that is more reliable and easier to use.
