    Does the RS4 RTR come stock with a 2 speed transmission? Does anyone know (and can maybe explain) what spur gears it has (and what the heck they do)?

    I'm just lost on the actual "gear setup"... I don't have the vocabulary to ask what I want to know. Basically I want to smoke my tires with one setup and have a second setup that I can hit the best top end. What are some examples of what I'd need to do/buy to get this done?

    And I'm pretty sure I've got the T-15 engine in it. I don't know if that's the same as the one you named.

    Yea , I know you have the t-.15, as far the gearing drop a couple teeth on the pinion gear thats the clutch bell . What is it now 15,16 teeth. The .12 was the RS4 3.
