Wafflet runs a t4 chassis and I tried it for a short time. I didnt like it. It made the car feel dead. Turned like a limo. But I was running on a right indoor track. I would give it a try if I were you, but go all the way. Dont make it a half and half. put your v2's on with the b4 towers and arms. you will need turnbuckles also. As far as setup, your can start with the current b4 setups and use a v2 shock package, but I would tun a shorty. You might want to try and run it without and lead accept from the 1/2 oz to balance the receiver and esc, or maybe even center line the electronics to make it more responsive.
