Can I use these parts off my OpenRC Truggy for the OpenRC Formula car?

Can I use these parts off my OpenRC Truggy for the OpenRC Formula car?

Below is a list of the electronics I used for my Truggy:

Motor and ESC: http://www.hobbyking.com/hobbyking/store/__25138__Turnigy_TrackStar_Waterproof_1_10_Brushless_Power_System_4000KV_80A.html
Battery: http://www.hobbyking.com/hobbyking/store/__10301__Turnigy_4000mAh_2S_40C_Lipo_Pack.html
Servo: http://www.hobbyking.com/hobbyking/store/__8776__BMS_620MG_High_Torque_Servo_Metal_Gear_9_1kg_15sec_50g.html

I will probably need a smaller battery.

Any idea if this will work?
