That servo is not even close to the amount of torque you need. Don't skimp on servos. Servos are worth the price because you'll have them a long time. Cars eventually wear out, but the electronics just get transplanted into the next car.

You'll want something with at least 250oz of torque.

I would also save up your money for the Castle system. The Novak HV systems are not up to the task of moving 1/8 scale truggies. I've personally witnessed one catch fire down the straight away.
