Why you should do the relay mod
 

I can give you a couple reasons to do the relay mod to your car.Even if you use the stock motor and drive around for fun in the kitchen.
#1 you get more power to motor and the car is faster.
#2 The steering on your car will react faster and stronger because the relay is by passing the circuit board when giving power to the motor.
#3 you don't get a loss of power when you make turns.
#4 your car will run better over all:D :D :D :D :D :D :D :D :D
That's what it is all about.

heh i will oneday do the relay mods.but i dont want to order them..id rather just buy it at radioshack or what not...

You can't beat $2.00 for a pre wired relay mod from tinracers.com and then you only have to solder a few wires:D
