The TLR Race Team has done extensive testing over the summer running multiple different lengths of prototype chassis to determine which offers the best performance for the 22 2.0. Needless to say, the chassis testing resulted in optimal performance from the -2.5mm length prototype, and TLR has now brought this to market. The -2.5mm wheelbase helps the 22 2.0 enter the turn a little quicker, rotate quicker and have better drive off the turn, which improves the overall balance and feel, especially in mid-motor. This setup improvement helped Dakotah Phend win the 2014 ROAR Nationals with Ryan Maifield winning A3 for a TLR A-Main Sweep.
The chassis also keeps the competitive stock racers in mind, having additional pockets milled throughout to lighten the chassis by 15-17g each. This lighter chassis makes it even easier to get the 22 2.0 down to the ROAR minimum weight, but has shown no signs of being less durable than the stock chassis. The -2.5mm chassis is a direct fit part that will replace the stock 22 and 22 2.0 chassis with no other modifications required.
