fitting a large pinion into this car with the stock motor mount is a bitch.
i ended up having to take both spur mounts off the chassis as well as the motor mount just to get the pinion on.
not to mention the challenge of actually mounting the motor and pinion and setting mesh.
i also had to dremel out some of the inside of the rear part of the upper deck so it would clear the pinion shaft.
3racing didnt give much thought to small spur / large pinion combinations.
i ended up using this combo..
