Just installed the +8 chassis. WOW! what a difference, the car isnt twitchy at all, can be thrown into corners a stock version of the car would have a s***fit over. Such an improvement, it is by far now the best handling car I have ever driven and I have driven them all, on par now with a decked out Kyosho RB5 with the Big Bores and all that jazz. Changed nothing about my setup other then not putting the weight I used to run with the standard chassis, the car simply doesnt need it anymore.
