Thank you WRXTC, Turbonium, and Burlap for the info. I will surely order them from my hobby shop this week.
On another note, I cannot believe how well this car drives. The stability is amazing with the stock setup.
I also forgot to mention these problems and observations I had last night while racing.
1. For the rear pulley, where the 2 belts meet, I noticed there's no "seperator" to seperate the two belts if they should ever meet. Is this a problem with some cars?
2. While racing, my rear belt "flipped" somehow. I'm pretty sure I have the proper tension, not too tight, not too loose. It still remained tight enough so it could turn the rear diff without slipping.
